Turbine Steam-Consumption Calculator is a program that will calculate the steam consumption for a turbine of known power and efficiency. The program will determine the specific and actual steam consumption and the outlet steam enthalpy, entropy, temperature and quality.
Is there a rule of thumb that dictates how many steam turbines you need to successfully harvest all of the energy of any magma volcano submerged in water?
I am in a pretty poor environment in terms of means to obtain energy so I need igneous rock to feed hatches for coal and volcanoes for power.
I made one of these setups to work as a desalination station and I'm supplying 5 in-line turbines with steam. They produce over 500w each. I haven't tried it yet but you can also do a series-parallel combo and you can potentially increase to another row (so perhaps 10 turbines).
I think that's not entirely true. Only 2 turbines could be used, if the turbines should produce all the time. You used the wrong value for the calculation (Wrong: "Per Eruption Cycle" Right: "Per Activity Cycle"). And i think 2 turbines are only correct, if you don't bringt the condensed water back in the steam-camber. Otherwise the number of turbines should be a bit lower then 2.
The thing with submerging the volcanoes in water is that at some point the water will boil. Submerging is not really a long term solution. The current designs make use of the heat of the volcano, be it magma or metal volcano. For the metal volcano you can use just a bit of water and delete the heat with a steam turbine. It's a very easy and efficient setup.
As I was priming the system, I was down to running the dupes on hamster wheels just to keep oxygen production going! I know you may think it was stupid not to just harvest the oil for petroleum power, but it would require me to establish an infrastructure 3x as large just to get rid of the gasses that would be produced!
Noob tip: Make sure the steam turbines are fully enclosed in tiles before you go digging around them. The stuff in the oil biome is very hot and will choke them out until those printed lazybones remove the debris!
Thank god. I spend 60% percent time of playing GT experimenting how many X i need to supply an Y. Hum. Its an idea to make calculator. Ok. How much EU in the coal and coal coke if using basic steam generator? I think coal coke was nerfed in last updates of 5th. Also is the bronze boiler is the most efficent of 4?

Many people wonder why steam exiting a turbine must be condensed back to water instead of being transported directly back to the boiler, thus creating the need for cooling towers or other means of cooling. Although doing so would create piping difficulties, the main reason relates to efficiency. Consider the simple system shown in Figure 1 on parge 106 with a turbine that has no frictional, heat or other losses, meaning no entropy change (isentropic).
Now think about this example from a physical perspective. Calculations indicate that the steam quality at the turbine exhaust (at 1 psia condenser pressure) is 82 percent. This means 18 percent of the steam has condensed to water. However, the remaining steam takes up a specific volume of 274.9 ft3/lbm. The corresponding volume of water in the condenser hotwell is 0.016136 ft3/lbm. Thus, the condensation process reduces the fluid volume more than 17,000 times. The condensing steam generates the strong vacuum in the condenser, which actually acts as a driving force to pull steam through the turbine.
Thermodynamics show that work and efficiency of a steam generator improve with increased pressure. But consider a situation where steam pressure in increased to 2,000 psia from Example 2, in which the condenser pressure was 1 psia. (Note this as Example 4.) The main steam enthalpy becomes 1,474.1 Btu/lbm and the turbine exhaust enthalpy is 871.0 Btu/lbm. The turbine work output rises to 603.1 Btu/lbm (176.7 MW at 1,000,000 lb/hr steam flow) and the efficiency increases from 40.6 percent to 42.9 percent. (The primary reason why supercritical [>3208 psia steam pressures] have become popular for modern coal-fired boilers is to achieve gains in efficiency through higher pressure.)
But at 2,000 psia, the turbine exit steam quality is only 77 percent. This means 23 percent of the fluid exits as condensed water droplets. Such high moisture content can damage low-pressure turbine blades. A rule of thumb suggests 10 percent moisture at the turbine exhaust as an upper limit. Reheating the steam helps alleviate this difficulty. Figure 2 on page 110 shows a steam generator and turbine with a reheat system.
Main steam is at 2,000 psia, 1,000 F, and has an enthalpy of 1474.1 Btu/lbm. The steam extraction (cold reheat) pressure is 300 psia, which equates (isentropically) to a cold reheat temperature of 485 F and enthalpy of 1248.1 Btu/lbm. Assume no pressure drop through the reheater and a hot reheat temperature of 1,000 F, producing reheated steam with an enthalpy of 1526.5 Btu/lbm. Calculations show that the reheating process improves the turbine exhaust steam quality from 77 percent to 90 percent. Because the steam quality increases, the turbine exhaust enthalpy increases slightly to 1,003.9 Btu/lbm.
Calculation of the work output, boiler heat input and efficiency of this example becomes slightly more complicated, as in this case where work is done by two separate steam feeds to the turbine and heat is added to two, separate steam systems in the boiler. The unit work equation is:
The values outlined in these examples are greater than normal because allowances were not made for heat losses in the boiler, inefficiencies in the turbine, frictional losses in the piping and other entropy-related factors. Nonetheless, these examples illustrate the fundamental principles and importance behind the operation of several important steam-generating components or subsystems. Numerous instances exist where power engineers have been involved with condenser performance improvement projects that have resulted in net savings of $500,000 to $1.5 million annually at just one plant.
