Nuclear power plants mostly need a lot of water. The steam production rate can also be calculated using the energy consumption: 1 Heat exchanger consumes 10MW, so it's putting 10,000,000 joule of energy into heating water/steam per second. factorio offshore pump heat exchanger ratio . If your heat pipe is too long, your reactors will max out at 1000 C before your heat exchangers can reach a steady state of 500 C, and and you'll start to waste heat. by Bauer Wed Jan 08, 2020 3:04 pm, Post Is there any info about how much water per second Heat Exchangers use? by Amarula Fri Nov 29, 2019 3:09 pm, Post and our 1 Answer. All rights reserved. 412.36 Water requires 1 ( 0.34) Offshore Pumps (1200 per Offshore Pump ). I get that offshore pumps produce 1200 units of water per second. Geplaatst op 3 juli 2022 door . And probably how many Offshore Pumps you need for them? By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. The heat can be used to convert water to steam using a heat exchanger and the steam can be consumed by steam turbines to produce power. Includes pipe, pipe to ground, pump, offshore pump, heat pipe. Designed for supporting scaled up machines from "Schall Machine Scaling" mod. A perfect square of reactors has the highest theoretical efficiency, but at 3x3 and above you'll have reactors surrounded on all 4 sides and have no way to load the uranium fuel cells. How do you set up a reactor to get enough water to keep producing steam? Each boiler is capable of producing enough 165C steam for two steam generators. A "close enough" ratio is 20:24:1 accumulators to solar panels to megawatts required (for example, a factory requiring 10 MW can be approximately entirely powered, day and night, by 200 accumulators and 240 solar panels - this approximation differs from optimal only in that it calls for 20 extra solar panels, which is negligible but remember that the difference between the "close enough" ratio and the optimal ratio increases as you add more solar panels). Cookie Notice Press question mark to learn the rest of the keyboard shortcuts. Hence, each water pump can support a maximum of 40 steam generators. A powered nuclear reactor outputs 40 megawatts of heat, plus an additional 40 megawatts for each powered nuclear reactor directly adjacent to it. They produce electricity by consuming steam, using water pumped from an offshore pump that was heated to 165C steam with boilers or to 500C steam with heat exchangers. I think it is easiest to just have an abundance of storage tanks for the steam. Give exchanger max heat you can then let the exchanger turn 25k water into steam. Also iirc tanks limit liquid throuput when it flows through them, so try connecting them on the side and not in-line if you have to at all. One steam engine consumes 30 steam per second, and one offshore pump produces 1200 water per second, so each offshore pump produces enough water to supply 40 steam engines: 1200 unit/s 30 units/s = 40. Neighbor bonuses make nuclear very efficient: 1 reactor = 40MW = 4 exchangers = 7 turbines Don't know how to use a machine? They only work when they're above 500 C, and have a maximum temperature of 1000 C. Temperatures above 500 don't increase efficiency; the exchanger will just store the heat, which it can then use later. fox hill country club membership cost.

Valve Corporation. HolyGarbage . Steam engines have two ports, allowing excess steam to flow through. by leitk Mon Dec 02, 2019 4:29 am, Post Thus, they can buffer 500 MJ of heat energy across their working range of 500C to 1000C, and require 485 MJ of energy to warm up from 15C to 500C when initially placed. (Except that you can potentially turn 8 gigajoules of uranium fuel cell into 40 gigajoules of heat. A reactor without neighbor bonus needs 4 heat exchangers so that all its heat gets consumed. Optimal ratio is 1 offshore pump for every 20 steam turbines; or, 25 offshore pumps for every 291 heat exchangers. At full 10 MW load this is 103.096 water per second. Using steam engines for power does not produce pollution, however using boilers to heat up the water does. In vanilla factorio, without mods which change any of these values, the optimal ratio will be the same. and another post in that thread (which calculates the solar panel to megawatt ratio in a different way). Perfectly optimal solar network (Factorio forums), 1 solar panel produces 42KW after factoring in the night (Factorio forums), https://wiki.factorio.com/index.php?title=Power_production&oldid=182968. The maximum length of heat pipe you can use depends on the combined distance of your heat exchangers from your reactors. Do your pipes have water? All trademarks are property of their respective owners in the US and other countries. Each heat exchanger converts 103 water to 103 steam, feeding 1.72 turbines. Valve Corporation. The current optimal ratio is 1 offshore pump to 20 boilers to 40 steam engines. Reddit and its partners use cookies and similar technologies to provide you with a better experience. Electricity has to be produced before it can be transferred to consumers over the electric system. Ratio of reactors to whatever is 2x2 480MW reactor to 10MW heat exchanger, ratio of reactors to miners is 1:4 iirc, so double that miners. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. I've confirmed that the true value is indeed 5.82, and updated everything accordingly. Do the numbers in the "beacons" column represent the number of modules or the number of beacons? Here are the total requirements for certain amounts of reactors, with everything rounded up to guarantee maximum energy production. Until then it is advisable to not use more than one pump per water network. by Honktown Mon Jan 06, 2020 6:52 pm, Post by steinio Fri Jan 03, 2020 4:52 pm, Post The main thing to remember is that Factorio generally follows the laws of thermodynamics; if your nuclear reactor produces 40 megawatts of heat, you can get a maximum of 40 megawatts of electricity out the other side. Sushi Belt question : r/factorio. Originally posted by Alaskan Glitch: The ratio is one water pump will supply a maximum of 20 boilers with water. The glow of the heat pipes indicates temperature, with left ends being at the upper limit of 1000C. One exchanger 3 storage tanks plus inf heat. One steam engine consumes 900kW of energy stored in steam, so each boiler can supply 2 steam engines: 1.8MW 0.9MW = 2. by mrvn Wed Jan 08, 2020 3:45 pm, Powered by phpBB Forum Software phpBB Limited. This is taken from Accumulator / Solar Panel Ratio (which calculates this in an impressive mathematical way!) To heat up 1 unit of water 1 degree, 200 joules are needed, so the heat exchanger is heating up water by 50,000C in total. Heat exchanger heats 15C water to 500C steam; It takes 0.2 kJ of burner energy to raise 1 water 1C; Steam is consumed by steam turbines at a rate of 60 units per second; (500C - 15C) 0.2 kJ 60 units = 5820 kW, or 5.82 MW. A heat exchanger consumes 10 MW. An offshore pump produces 1200 units of water per second, which is enough for 116.4 MW. 1 offshore pump: 20 Steam Turbines. If not, ensure all. Yogi Berra. Factorio - The Best Nuclear Power Ratio To generate ten fuel cells, you will need one U-235 cell and nineteen U-238 cells. One Offshore pump can fully supply 12 (11.64) . Then you just connect the reactors to exchangers and exchangers to turbines, also you need about 1 water pump per 10 exchangers (in vanilla). One steam engine consumes 900kW of energy stored in steam, so each boiler can supply 2 steam engines: 1.8MW 0.9MW = 2. by eradicator Fri Nov 29, 2019 4:43 pm, Post This means the energy that was put into the steam to heat it to a higher temperature is wasted. Steam engines will automatically adjust their power production and steam usage based on the current demands of the electricity network. using 3 pumps and a tank, you can feed 28 heat exchangers. There's no clear ratio as you need to account for heat bonus from other reactors but it's quite easy to calculate yourself, if you fuel the reactors it will show you produced heat in MW (with bonus) you just sum up all reactors and divide by heat exchanger power (all power/power per 1 hear exchanger) to get the number, then you do the same for turbines (all power/power per 1 turbine). This means a single unit of 500C steam has 5.82MW / (60/s) = 0.097 MJ of energy. by Honktown Mon Dec 02, 2019 1:56 pm, Post Also, before you set it up, make sure you nuke any landfill land to get a little pollution absorption to help manage your Fun fumes cloud. Don't ask me how that works.) 1 25k tank water disconnected from water input. 20. Each heat exchanger takes a maximum input 10 megawatts of heat and uses it to heat water into steam. makes troubleshooting easier. Id probably put it on or next to either of the lakes in the middle north or middle south. 40 MW of power output is consumed by 4 Heat Exchangers (10MW per Heat Exchanger ). A reactor produces 40MW, plus another 40MW for each active neighbouring reactor. 4 Heat Exchangers boil 412.36 Water to Steam per second (103.09 per Heat Exchanger ). Build the reactor over a lake, with careful placement of landfill you can have pumps directly feeding each end of the heat exchanger line. Press question mark to learn the rest of the keyboard shortcuts. Each turbine consume 60 water/s so 1200/60=20 turbines. Heat exchangers are pipes too. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. 75 crafting speed, while the induction furnaces use 3 * 1, so the ratio could be fine tuned a bit. It produces 1200 units of water per second. If you want a ratio that's a little easier to remember, those are probably your best bet. EDIT NOTE: The original version of the post used the wrong output for steam turbines (5.8 MW instead of 5.82). For each 100% neighbor bonus, the reactor needs 4 more heat exchangers. The lake under the oil field looks like a nice place, letting you place offshore pumps near the center, with the turbines extending to land. Heat exchangers will not produce steam until they reach 500C. Is steam able to reach all steam engines? Use the lake west of your copper mine. Press J to jump to the feed. What I can't find is how much water a heat exchanger *consumes* to produce the 103ish steam per second. The offshore pump produces water from a lake or ocean. 120 MW ^Note: Pumps, Steam Turbines and Power are approximate for easier build ratios. I have been reading all about Nuclear power so I can convert my factory. On a lake, very carefully - they consume a monstrous amount of water, and having the multiple required offshore pumps integrated directly into the design is often worth the hassle of wrangling landfill. by gGeorg Sat Dec 07, 2019 1:00 am, Post Heat pipes (also in reactors and heat exchangers) glow with high temperatures. Stuck in a mission? by astroshak Wed Jan 08, 2020 11:15 am, Post (100% neighbor bonus per adjacent reactor). The above ratio can be calculated from information available in-game: One boiler consumes 1.8MW of fuel and produces energy stored in steam at 100% efficiency. It takes 200J to heat 1 unit of water by 1C. In practice, there is. A heat exchanger produces 10 MJ a second, therefore it produces 10MJ / 0.097MJ = 103.0927835 steam per second. I concur the ratio is 1:1 cerified through testing. See also the applied power math tutorial to answer the question how much coal do I need? Heat exchangers have different dynamics to actual pipes. For more information, please see our Each steam turbine take a maximum input of 60 units of 500 C steam per second and outputs 5.82 megawatts of electricity; the 5.8 megawatts listed on the tooltip is rounded. SmartAlec105 having more than 2 steam engines per boiler could do that. by Amarula Fri Jan 03, 2020 4:45 pm, Post The main thing to remember is that Factorio generally follows the laws of thermodynamics; if your nuclear reactor produces 40 megawatts of heat, you can get a maximum of 40 megawatts of electricity out the other side. Water: is a liquid which can be infinitely extracted from water tiles using an offshore pump; Steam: is a gas you can create by heating water in a boiler or heat exchanger; Other Factorio Guides: Boiler to Steam Ratio; Solar Panel Ratio; Console Commands & Cheats by disentius Fri Nov 29, 2019 9:15 pm, Post 6, crafting time is 15s, producing 0. Remember that water in pipes still obeys Factorio physics; if you pipe your water a long distance, you may not get the full 1200/s. Look at the windows in the pipes, hover over the pipes! factorio offshore pump heat exchanger ratio All rights reserved. Are there enough steam generators (boilers, heat exchangers)? Exchanger outputs to 2 tanks. Place some pipes or a tank at the end to see if there is really water coming through. If I know how much energy i'm outputting from my reactors -> figure out how many turbines -> figure out how many heat exchangers -> How many pumps do I need? Introduction Troubled by pipes having low flow rates? If you run an odd number of reactors, you should have a 2 by X rectangle with one reactor dangling off the end. Refer to Francis John play through video on YouTube on nuclear power. All rights reserved. Final ratio: 25 offshore pumps : 291 heat exchangers : 500 steam turbines. This means that you need 1.428 MW of production (of solar panels) and 100MJ of storage to provide 1 MW of power over one day-night cycle. Since steam is produced from water in a 1:1 ratio, this also means that 103 units of water are consumed per second. Create an account to follow your favorite communities and start taking part in conversations. Heat exchangers produce ~103 steam with a temperature of 500C every second. The water calculation has me stumped. The steam produced is exactly 500C hot, even if the exchanger is hotter. You can check the usage on the turbines as well as the production stat on the offshore pump. So the 50,000C are enough to heat up 103 units of steam per second, since 50,000 / 485 = 103.09. Community-run subreddit for the game Factorio made by Wube Software. Then have a simple trigger than turns your nuclear plant on and off based on the storage tank steam levels. Steam that has a higher temperature than the maximum temperature of the steam engine (165C) is consumed at the normal rate (30 units/s), and does not yield more electricity. There are multiple methods to produce electricity: Each steam engine needs 0.5 boilers when running at full capacity. Heat exchangers produce ~103 steam with a temperature of 500C every second. My own personal Factorio super-power - running out of power. All trademarks are property of their respective owners in the US and other countries. you can put 4 heat exchangers at the end of ~135 heat pipes, but you can put 16 heat exchangers only at the end of ~50 heat pipes. Each turbine consume 60 water/s so 1200/60=20 turbines. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. by mrvn Wed Jan 08, 2020 3:42 pm, Post One offshore pump can supply 20 boilers and 40 steam engines. These fuel cells are then burned in a nuclear reactor to create heat. These include the power generation of a solar panel, the energy storage of an accumulator, the length of a day, and the length of a night. However you did warn me: Save often and reload if necessary during landfilling. Pump Ratio ^ 1. In general, nuclear power is produced by the following production chain: Uranium ore is mined and processed to uranium-235 and uranium-238, then uranium fuel cells are created from the two. Not sure where you got those numbers from, but in 0.15, small pumps and offshore pumps pump at exactly the same rate: 1200 fluid/s. But the water only gets heated up from 15C to 500C, so by 485C. I found the cheatsheet and wiki which have been quite helpful. A theory without practice is dead, practice without a theory is blind, this quote is attributed to commander Alexander Suvorov. This equation could also be used to remember the vanilla optimal ratio given its simplicity. The most heat exchangers I've been able to fit on a single length of heat pipe is 30 heat exchangers on 44 heat pipes; any more than that incurs significant heat loss. As each heat exchanger produces 10 MW, the optimal ratio is 500 steam turbines for every 291 heat exchangers. You can also have some steam tanks with additional turbines for power spikes (laser turrets etc) as reactors always work with 100% power tanks will store steam when you're not using it all), Factorio Cheat Sheet - That's all the information you need. Neighbor bonuses make nuclear very efficient: 1 reactor = 40MW = 4 exchangers = 7 turbines, 2 reactor = 160MW = 16 exchangers = 28 turbines, 4 reactor = 480MW = 48 exchangers = 83 turbines.

Espaol - Latinoamrica (Spanish - Latin America), https://wiki.factorio.com/Tutorial:Nuclear_power#Neighbor_bonus. by disentius Tue Jan 07, 2020 9:36 pm, Post by Honktown Fri Jan 03, 2020 8:34 pm, Post Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. This link for calculations. The flow between pipes and heat exchangers is also different to pump to heat exchangers. The heat exchanger exchanges heat between a heat connection and water to produce steam. The above ratio can be calculated from information available in-game: One boiler consumes 1.8MW of fuel and produces energy stored in steam at 100% efficiency. by Amarula Mon Dec 02, 2019 3:51 pm, Post As shown, making the heat pipes thicker allows supporting heat exchangers that are farther away. Is the factory producing enough fuel (coal, solid fuel, uranium fuel cells)? The number of boilers can be derived from the number of steam engines: 40 2 = 20. It takes 200J to heat 1 unit of water by 1C. which, given the default time lengths of: day = 12500/60 s; dawn or dusk = 5000/60 s; night = 2500/60 s, and the default: Solar_power = 60 kW; Accumulator_energy = 5 MJ = 5000 kJ, gives the optimal ratio of 0.84 accumulators per solar panel. Get some landfill to straighten the edge youre gonna use. There are also times between day and night called dusk and dawn which complicate the calculations. So we know that one offshore pump can supply 20 boilers but is that the same for heat exchangers? Any experiences/suggestions/comments are welcome. turbines, exchangers and reactor ratios will vary due to neighbor bonuses. Your other big concern is fluid flow, and the main constraint is the heat flow along heat pipes. can you post a screenshot/blueprint? The optimal ratio of accumulators per solar panel relies on many values in the game. The Factorio devs plan some refactoring for the upcoming version 0.17. A steam turbine consumes 60 units of steam per second, which is 5.82 MW. by astroshak Sat Jan 04, 2020 1:58 am, Post Finally, after 20 hours of work, I present the flowchart for Pyanodon Space Science! Post So far I have built/replaced 3 reactor sectors to be on the lake rather than beside the lake, and I am pretty happy with the results (600 fewer pipes, 800 fewer underground pipes). Does the game consider 1 water = 1 steam (just a different temperature?) A heat exchanger consumes 10 MW. -adding a second off-shore pump to start off with twice as much water (in theory); -putting in more pumps, say one pump for every underground pipe; -putting in a complete second line from off-shore pump to heat exchangers with a pump every 5 underground pipes. by azesmbog Fri Nov 29, 2019 4:19 pm, Post Privacy Policy. So a 2x2 block produces 480MW (4*3*40). Press J to jump to the feed. Thanks. As far as I can tell, the absolute smallest perfect-ratio setup possible is: which would require an input of 1.46 uranium fuel cells per second and output a cool 46.56 gigawatts of electricity.

Fresh water is at 15C while the steam produced by heat exchangers and consumed by steam turbines is at 500C, a difference of 485C, so you need 1 unit of water for each 97kJ, which is roughly 10.3 units per MJ. Now you have 0 waste of fuel. Community-run subreddit for the game Factorio made by Wube Software. What does clicking on an item's icon in the "Factory" tab do? Looking for efficient setups? (Low quality because reddit wouldn't let me upload the full png) redditads Promoted. by Honktown Tue Jan 07, 2020 10:30 pm, Post A heat exchanger produces 10 MJ a second, therefore it produces 10MJ / 0.097MJ = 103.0927835 steam per second. Reddit and its partners use cookies and similar technologies to provide you with a better experience. The steam production rate can also be calculated using the energy consumption: 1 Heat exchanger consumes 10MW, so it's putting 10,000,000 joule of energy into heating water/steam per second. In a vanilla game that's. what, 1k science a minute? The more heat exchangers you want to put on a single length of heat pipe, the shorter that heat pipe has to be to ensure minimal heat loss; e.g. The optimal ratio is 0.84 (21:25) accumulators per solar panel, and 23.8 solar panels per megawatt required by your factory (this ratio accounts for solar panels needed to charge the accumulators). Heat exchangers have a heat capacity of 1 MJ/C. Additional comment actions. Nuclear reactors have a maximum temperature of 1000 C. Unlike boilers, nuclear reactors will not slow or stop their fuel consumption if their output isn't being used; they'll constantly use up fuel cells at the normal rate of 1 fuel cell / 200 seconds. One offshore pump can supply 20 boilers and 40 steam engines. Heat pipes are used to transfer heat from your nuclear reactors to your heat exchangers. Geplaatst op 3 juli 2022 door . It must be placed on a shoreline of a body of water on the map, and connected to a pipe or other object that accepts liquids. Mark IIIs are unable to complete a full cycle without going into meltdown and thus need to be shutdown mid-cycle in order to deal with the high amount of excess heat. It's recommended to build them near or on bodies of water, as that lets you place offshore pumps where ever you want. You may also use this to rectify brownouts/blackouts. Each offshore pump outputs 1200 units of water per second. You can sideload water for a 1.1 GW plant. u/asdjfsjhfkdjs calculated the convergents of 500:291, and found that 7 : 4 and 55 : 32 are both fairly accurate approximations. The technical implementation details of Factorio's pipe system still have some room for improvement. r/factorio . There is a handy table on the factorio wiki listing the throughput for different lengths of pipe between pumps. Create an account to follow your favorite communities and start taking part in conversations. The heat exchanger exchanges heat between a heat connection and water to produce steam . Yes, there is also a maximum throughput for water that depends on the distance the . I wasn't sure if Heat exchanger converts 1 water into 1 steam and there is nothing written in its tooltip. All trademarks are property of their respective owners in the US and other countries. Factorio version: 1.1 Downloaded by: 1.88K users WHAT IS OFFSHORE P.U.M.P.S.? The true value comes from the following facts: It takes 1 kilojoule of thermal energy to raise 5 units of water/steam 1 C, You've heated water from 15 C to 500 C; 500 - 15 = 485, Consuming steam in turbines gives you the same amount of energy back as electricity, Steam is consumed by steam turbines at a rate of 60 units/second. 12. 9.89 gigawatts is a lot. #footer_privacy_policy | #footer . This produces the 1:20:40 ratio. by mrvn Fri Nov 29, 2019 4:41 pm, Post If you overbuild reactors, you can end up wasting a lot of fuel cells without realizing it. The lake under the oil field looks like a nice place, letting you place offshore pumps near the center, with the turbines extending to land. Ratio of reactors to whatever is 2x2 480MW reactor to 10MW heat exchanger, ratio of reactors to miners is 1:4 iirc, so double that miners, You will need 1x2 chunks space near water, so anywhere, maybe next to Oil Field's Uranium patch. Valve Corporation. The ideal ratio is 4 Reactors, 48 Heat Exchangers, 83 Steam Turbines and 5 Water pumps. One pump can supply up to 20 boilers. This allows steam engines to be chained together. Change fluidbox height and base level of boiler, steam engine and pump to improve fluid flow. Don't ask me how that works.). It does not require electricity or fuel to operate. you should have a 2 by X rectangle with one reactor dangling off the end. When producing power, the steam engine will display a working animation: https://wiki.factorio.com/index.php?title=Steam_engine&oldid=188232. Heat exchangers produce 103 steam/second.This can be calculated by relying on steam turbine data: A steam turbine consumes 60 steam/second and produces 5.82MW (assuming 500C steam). This layout produces 40 MW output ( 1 SRE ). Each heat exchanger converts 103 water to 103 steam, feeding 1.72 turbines. If you inexplicably want to go back to a 4 year old build of Factorio then you will need to build 14 boilers in a row (they each used to heat the water up by a little bit), followed by 10 steam engines. Additional comment actions. Someone already mentioned the normal "build on a lake" strategy. 15 - Factorio Factorio Forums View topic - 0. They produce electricity by consuming steam, using water pumped from an offshore pump that was heated to 165C steam with boilers or to 500C steam with heat exchangers.
