4 Heat Exchangers boil 412.36 Water to Steam per second (103.09 per Heat Exchanger ). If you run an odd number of reactors, you should have a 2 by X rectangle with one reactor dangling off the end. Introduction Troubled by pipes having low flow rates? 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. 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). 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. Nuclear power plants mostly need a lot of water. 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. Each turbine consume 60 water/s so 1200/60=20 turbines. 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. The ideal ratio is 4 Reactors, 48 Heat Exchangers, 83 Steam Turbines and 5 Water pumps. The steam produced is exactly 500C hot, even if the exchanger is hotter. (Low quality because reddit wouldn't let me upload the full png) redditads Promoted. The true maximally efficient layout is a 2 by X rectangle; this gives you access to every reactor. Post So a heat exchanger generated 103 steam per second is 103 water per second I need from my offshore pump. 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. by Honktown Fri Jan 03, 2020 8:34 pm, Post This page was last edited on 27 October 2020, at 13:19. turbines, exchangers and reactor ratios will vary due to neighbor bonuses. A heat exchanger consumes 10 MW. Since steam is produced from water in a 1:1 ratio, this also means that 103 units of water are consumed per second. So we know that one offshore pump can supply 20 boilers but is that the same for heat exchangers? 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. Your other big concern is fluid flow, and the main constraint is the heat flow along heat pipes. Reddit and its partners use cookies and similar technologies to provide you with a better experience. For each 100% neighbor bonus, the reactor needs 4 more heat exchangers. Don't know how to use a machine? Each heat exchanger converts 103 water to 103 steam, feeding 1.72 turbines. Stuck in a mission? Final ratio: 25 offshore pumps : 291 heat exchangers : 500 steam turbines. One exchanger 3 storage tanks plus inf heat. 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. All trademarks are property of their respective owners in the US and other countries. A steam turbine consumes 60 units of steam per second, which is 5.82 MW. All rights reserved. Exchanger outputs to 2 tanks. You can sideload water for a 1.1 GW plant. (100% neighbor bonus per adjacent reactor). 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? can you post a screenshot/blueprint? by mrvn Wed Jan 08, 2020 3:45 pm, Powered by phpBB Forum Software phpBB Limited. All trademarks are property of their respective owners in the US and other countries. What does clicking on an item's icon in the "Factory" tab do? by Honktown Mon Dec 02, 2019 1:56 pm, Post The heat exchanger exchanges heat between a heat connection and water to produce steam . One boiler consumes 1. (Except that you can potentially turn 8 gigajoules of uranium fuel cell into 40 gigajoules of heat. by leitk Mon Dec 02, 2019 4:29 am, Post Valve Corporation. 20. https://wiki.factorio.com/index.php?title=Heat_exchanger&oldid=175988. This means the energy that was put into the steam to heat it to a higher temperature is wasted. fox hill country club membership cost. A theory without practice is dead, practice without a theory is blind, this quote is attributed to commander Alexander Suvorov. In theory, there is no difference between theory and practice. However I want to do a different configuration and want to plan out how many of each type of component I need. 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. Does the game consider 1 water = 1 steam (just a different temperature?) you should have a 2 by X rectangle with one reactor dangling off the end. Is the factory producing enough fuel (coal, solid fuel, uranium fuel cells)? r/factorio . Until then it is advisable to not use more than one pump per water network. The maximum length of heat pipe you can use depends on the combined distance of your heat exchangers from your reactors. One steam engine consumes 900kW of energy stored in steam, so each boiler can supply 2 steam engines: 1.8MW 0.9MW = 2. I wasn't sure if Heat exchanger converts 1 water into 1 steam and there is nothing written in its tooltip. The current optimal ratio is 1 offshore pump to 20 boilers to 40 steam engines. This page was last edited on 13 September 2019, at 23:48. u/asdjfsjhfkdjs calculated the convergents of 500:291, and found that 7 : 4 and 55 : 32 are both fairly accurate approximations. by disentius Tue Jan 07, 2020 9:36 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. 40 MW of power output is consumed by 4 Heat Exchangers (10MW per Heat Exchanger ). 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. The flow between pipes and heat exchangers is also different to pump to heat exchangers. So you have 10 + 12 = 22 pipes. If the only effect the mod has on the game is it changes the total length of one day, without changing the ratio of dusk: day: dawn: night, then the equation can be simplified as. by Bauer Wed Jan 08, 2020 3:04 pm, Post All trademarks are property of their respective owners in the US and other countries. Looking for efficient setups? The offshore pump produces water from a lake or ocean. That's actually just odd. The throughput of a fluid pipe depends on the length of said pipe, but you can put in pumps to pressurize the pipe and increase the throughput. 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. Sushi Belt question : r/factorio. 75 crafting speed, while the induction furnaces use 3 * 1, so the ratio could be fine tuned a bit. Someone already mentioned the normal "build on a lake" strategy. Each offshore pump outputs 1200 units of water per second. 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. 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. 9.89 gigawatts is a lot. EDIT NOTE: The original version of the post used the wrong output for steam turbines (5.8 MW instead of 5.82). Steam engines are the most basic electricity generator, available to the player at the start of the game. by Honktown Mon Jan 06, 2020 6:52 pm, Post A heat exchanger produces 10 MJ a second, therefore it produces 10MJ / 0.097MJ = 103.0927835 steam per second. One offshore pump can supply 20 boilers and 40 steam engines. At full 10 MW load this is 103.096 water per second. I concur the ratio is 1:1 cerified through testing. Using steam engines for power does not produce pollution, however using boilers to heat up the water does. Heat pipes are used to transfer heat from your nuclear reactors to your heat exchangers. Is steam able to reach all steam engines? By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. I think it is easiest to just have an abundance of storage tanks for the steam. where game_day is the number of seconds in the game day which is 25000/60 s by default. Heat exchangers have different dynamics to actual pipes. Originally posted by Alaskan Glitch: The ratio is one water pump will supply a maximum of 20 boilers with water. Added high graphics quality option for the steam engine. and our Refer to Francis John play through video on YouTube on nuclear power. 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 steam engine consumes 900kW of energy stored in steam, so each boiler can supply 2 steam engines: 1.8MW 0.9MW = 2. A compendium of the most common Factorio game facts, such as build ratios, tips/tricks, . Heat exchangers will not produce steam until they reach 500C. Community-run subreddit for the game Factorio made by Wube Software. Ratio of heat exchangers to turbines is 1:2, don't bother building lots of pipes for 10% les turbines. All rights reserved. Place some pipes or a tank at the end to see if there is really water coming through. Do the numbers in the "beacons" column represent the number of modules or the number of beacons? There are mods that can add landfill tiles to existing blueprints if you're up for modding and using a blueprint rather than making your own reactor, and this design is one of my favourites - not objectively "best" perhaps, but has a certain elegance that I deeply appreciate alongside a decent serving of entirely respectable practicality. by Amarula Fri Jan 03, 2020 4:45 pm, Post Don't ask me how that works.). Pump Ratio ^ 1. So I've run into an issue with water for my Turbines. A reactor without neighbor bonus needs 4 heat exchangers so that all its heat gets consumed. Build the reactor over a lake, with careful placement of landfill you can have pumps directly feeding each end of the heat exchanger line. You may also use this to rectify brownouts/blackouts. Press J to jump to the feed. by mrvn Fri Nov 29, 2019 4:41 pm, Post Doubled the heat capacity of water from 0.1kJ per degree per liter to 0.2kJ. This is taken from Accumulator / Solar Panel Ratio (which calculates this in an impressive mathematical way!) Or so. A reactor produces 40MW, plus another 40MW for each active neighbouring reactor. Hovering the mouse over a steam engine will display their current power production (Performance) and their possible power production (Available Performance), in a display on the right. For more information, please see our Steam engines will automatically adjust their power production and steam usage based on the current demands of the electricity network. Each heat exchanger converts 103 water to 103 steam, feeding 1.72 turbines. by Honktown Tue Jan 07, 2020 10:30 pm, Post Heat exchangers will not produce steam until they reach 500C. Here are the total requirements for certain amounts of reactors, with everything rounded up to guarantee maximum energy production. Create an account to follow your favorite communities and start taking part in conversations. 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. 1 25k tank water disconnected from water input. Tileable Nuclear Reactor Design. and another post in that thread (which calculates the solar panel to megawatt ratio in a different way). by astroshak Wed Jan 08, 2020 11:15 am, Post Reddit and its partners use cookies and similar technologies to provide you with a better experience. 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. 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. 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. 120 MW ^Note: Pumps, Steam Turbines and Power are approximate for easier build ratios. Finally, after 20 hours of work, I present the flowchart for Pyanodon Space Science! (Except that you can potentially turn 8 gigajoules of uranium fuel cell into 40 gigajoules of heat. Heat exchangers produce ~103 steam with a temperature of 500C every second. 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. 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. So a 2x2 block produces 480MW (4*3*40). But the water only gets heated up from 15C to 500C, so by 485C. Do your pipes have water? 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. 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. There are also times between day and night called dusk and dawn which complicate the calculations. If you overbuild reactors, you can end up wasting a lot of fuel cells without realizing it. HolyGarbage . It took me 4 days to figure out the ratios related to nuclear power, so I figured I'd share. 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. Press J to jump to the feed. Each heat exchanger takes a maximum input 10 megawatts of heat and uses it to heat water into steam. It's recommended to build them near or on bodies of water, as that lets you place offshore pumps where ever you want. I get that offshore pumps produce 1200 units of water per second. It takes 200J to heat 1 unit of water by 1C. Press question mark to learn the rest of the keyboard shortcuts. by steinio Fri Jan 03, 2020 4:52 pm, Post 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. Connect water tank to exchanger for exactly 25k units water. 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). One pump can supply up to 20 boilers. This means a single unit of 500C steam has 5.82MW / (60/s) = 0.097 MJ of energy. These fuel cells are then burned in a nuclear reactor to create heat. This allows steam engines to be chained together. Also, the optimal ratio is: 1 offshore pump / 14 boilers / 10 steam engines is that 10 for each boiler? Includes pipe, pipe to ground, pump, offshore pump, heat pipe. 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. Use the lake west of your copper mine. by azesmbog Fri Nov 29, 2019 4:19 pm, Post If you want a ratio that's a little easier to remember, those are probably your best bet. The heat exchanger exchanges heat between a heat connection and water to produce steam. The steam produced is exactly 500C hot, even if the exchanger is hotter. 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. Calculator for the Nuclear Reactor. This link for calculations. Click on an empty cell to place a nuclear power plant. I have been reading all about Nuclear power so I can convert my factory. 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). Press question mark to learn the rest of the keyboard shortcuts. by gGeorg Sat Dec 07, 2019 1:00 am, Post All rights reserved. makes troubleshooting easier. Each boiler is capable of producing enough 165C steam for two steam generators. 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. 1 offshore pump: 20 Steam Turbines. . Cookie Notice Yogi Berra. I've confirmed that the true value is indeed 5.82, and updated everything accordingly. However you did warn me: Save often and reload if necessary during landfilling. Each turbine consume 60 water/s so 1200/60=20 turbines. Now you have 0 waste of fuel. 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. This produces the 1:20:40 ratio. 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. Reddit and its partners use cookies and similar technologies to provide you with a better experience. There is a handy table on the factorio wiki listing the throughput for different lengths of pipe between pumps. If the player uses mods which change the power generation of solar panels, or the energy storage of accumulators, but not the length of days, a simplified version of this equation can be used. P UMPING U NITS M EETING P HYSICS S TANDARDS This mod started off as a project to sustain my most eco-unfriendly excessive water needs by implementing some Higher Tier Offshore Pumps. 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.
