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. An offshore pump produces 1200 units of water per second, which is enough for 116.4 MW. 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? In a vanilla game that's. what, 1k science a minute? 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. The optimal ratio of accumulators per solar panel relies on many values in the game. 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. (Except that you can potentially turn 8 gigajoules of uranium fuel cell into 40 gigajoules of heat. The heat exchanger exchanges heat between a heat connection and water to produce steam . 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. Now you have 0 waste of fuel. Change fluidbox height and base level of boiler, steam engine and pump to improve fluid flow. Community-run subreddit for the game Factorio made by Wube Software. It takes 200J to heat 1 unit of water by 1C. One exchanger 3 storage tanks plus inf heat. 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). Each turbine consume 60 water/s so 1200/60=20 turbines. 1 Answer. u/asdjfsjhfkdjs calculated the convergents of 500:291, and found that 7 : 4 and 55 : 32 are both fairly accurate approximations. Doubled the heat capacity of water from 0.1kJ per degree per liter to 0.2kJ. Each boiler is capable of producing enough 165C steam for two steam generators. Refer to Francis John play through video on YouTube on nuclear power. 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. This layout produces 40 MW output ( 1 SRE ). Steam engines have two ports, allowing excess steam to flow through. 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. However you did warn me: Save often and reload if necessary during landfilling. -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. 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. Valve Corporation. 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. A heat exchanger produces 10 MJ a second, therefore it produces 10MJ / 0.097MJ = 103.0927835 steam per second. by Honktown Mon Dec 02, 2019 1:56 pm, Post A compendium of the most common Factorio game facts, such as build ratios, tips/tricks, . Stuck in a mission? This page was last edited on 13 September 2019, at 23:48. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. It produces 1200 units of water per second. Factorio version: 1.1 Downloaded by: 1.88K users WHAT IS OFFSHORE P.U.M.P.S.? A steam turbine consumes 60 units of steam per second, which is 5.82 MW. What does clicking on an item's icon in the "Factory" tab do? Looking for efficient setups? 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. So a heat exchanger generated 103 steam per second is 103 water per second I need from my offshore pump. 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. Is there any info about how much water per second Heat Exchangers use? One pump can supply up to 20 boilers. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. you should have a 2 by X rectangle with one reactor dangling off the end. The offshore pump produces water from a lake or ocean. 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. 4 Heat Exchangers boil 412.36 Water to Steam per second (103.09 per Heat Exchanger ). This means a single unit of 500C steam has 5.82MW / (60/s) = 0.097 MJ of energy. 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. Cookie Notice 9.89 gigawatts is a lot. Get some landfill to straighten the edge youre gonna use. Does the game consider 1 water = 1 steam (just a different temperature?) chrisgbk 6 yr. ago Technically the HX consumes the water and outputs an equal amount of steam. All trademarks are property of their respective owners in the US and other countries. Build the reactor over a lake, with careful placement of landfill you can have pumps directly feeding each end of the heat exchanger line. Each turbine consume 60 water/s so 1200/60=20 turbines. This page was last edited on 16 February 2022, at 11:27. 1 offshore pump: 20 Steam Turbines. 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. where game_day is the number of seconds in the game day which is 25000/60 s by default. by Honktown Fri Jan 03, 2020 8:34 pm, Post However I want to do a different configuration and want to plan out how many of each type of component I need. fox hill country club membership cost. 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 lake under the oil field looks like a nice place, letting you place offshore pumps near the center, with the turbines extending to land. Any experiences/suggestions/comments are welcome. 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 produces the 1:20:40 ratio. The heat exchanger exchanges heat between a heat connection and water to produce steam. Calculator for the Nuclear Reactor. I found the cheatsheet and wiki which have been quite helpful. Don't know how to use a machine? https://wiki.factorio.com/index.php?title=Heat_exchanger&oldid=175988. At full 10 MW load this is 103.096 water per second. factorio offshore pump heat exchanger ratio Exchanger outputs to 2 tanks. 412.36 Water requires 1 ( 0.34) Offshore Pumps (1200 per Offshore Pump ). 15 - Factorio Factorio Forums View topic - 0.

In vanilla factorio, without mods which change any of these values, the optimal ratio will be the same. Designed for supporting scaled up machines from "Schall Machine Scaling" mod. by astroshak Wed Jan 08, 2020 11:15 am, Post Yes, there is also a maximum throughput for water that depends on the distance the . 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. What I can't find is how much water a heat exchanger *consumes* to produce the 103ish steam per second. Place some pipes or a tank at the end to see if there is really water coming through. The steam produced is exactly 500C hot, even if the exchanger is hotter. Steam engines are the most basic electricity generator, available to the player at the start of the game. 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). Reddit and its partners use cookies and similar technologies to provide you with a better experience. A heat exchanger consumes 10 MW. You may also use this to rectify brownouts/blackouts. turbines, exchangers and reactor ratios will vary due to neighbor bonuses. by Bauer Wed Jan 08, 2020 3:04 pm, Post Optimal ratio is 1 offshore pump for every 20 steam turbines; or, 25 offshore pumps for every 291 heat exchangers. Each heat exchanger converts 103 water to 103 steam, feeding 1.72 turbines. Since steam is produced from water in a 1:1 ratio, this also means that 103 units of water are consumed per second. Additional comment actions. (Except that you can potentially turn 8 gigajoules of uranium fuel cell into 40 gigajoules of heat. It's recommended to build them near or on bodies of water, as that lets you place offshore pumps where ever you want. Heat exchangers have different dynamics to actual pipes. Someone already mentioned the normal "build on a lake" strategy. 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). 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. 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. When producing power, the steam engine will display a working animation: https://wiki.factorio.com/index.php?title=Steam_engine&oldid=188232. 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. Heat exchangers have a heat capacity of 1 MJ/C. by steinio Fri Jan 03, 2020 4:52 pm, Post 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 Amarula Fri Nov 29, 2019 3:09 pm, Post The flow between pipes and heat exchangers is also different to pump to heat exchangers. 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. I think it is easiest to just have an abundance of storage tanks for the steam. A heat exchanger produces 10 MJ a second, therefore it produces 10MJ / 0.097MJ = 103.0927835 steam per second. Heat exchangers will not produce steam until they reach 500C. This means the energy that was put into the steam to heat it to a higher temperature is wasted. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Final ratio: 25 offshore pumps : 291 heat exchangers : 500 steam turbines. This can be extended as far as you want; every additional 2 reactors will provide an additional 320 megawatts of heat output. Is the factory producing enough fuel (coal, solid fuel, uranium fuel cells)? by Amarula Fri Jan 03, 2020 4:45 pm, Post For more information, please see our This is taken from Accumulator / Solar Panel Ratio (which calculates this in an impressive mathematical way!) by eradicator Fri Nov 29, 2019 4:43 pm, Post by Honktown Tue Jan 07, 2020 10:30 pm, Post See also the applied power math tutorial to answer the question how much coal do I need? This link for calculations. Nuclear power plants mostly need a lot of water. by azesmbog Fri Nov 29, 2019 4:19 pm, Post I wasn't sure if Heat exchanger converts 1 water into 1 steam and there is nothing written in its tooltip. Privacy Policy. Press J to jump to the feed. Since heat exchangers consume 103.1 water each, a few dozen seems reasonable if . Valve Corporation. Press question mark to learn the rest of the keyboard shortcuts. Additional comment actions. #footer_privacy_policy | #footer . One offshore pump can supply 20 boilers and 40 steam engines. Includes pipe, pipe to ground, pump, offshore pump, heat pipe. The maximum length of heat pipe you can use depends on the combined distance of your heat exchangers from your reactors. Press J to jump to the feed. Heat exchangers will not produce steam until they reach 500C.
