I been struggling with this too. I beleive that it makes no economic or logical sense to construct a steam powered turbine generator until you hit a minimum of 500kw. The componets needed to run any such unit, steal too much power from the gross output of the unit as you go small scale, example 20kw. It would be great to build a small unit as such that could power and heat your home off of wood, coal, or other combustible materials. But consider the following: you need a furnace(Iduction draft and forced draft fans=negative watts)-boiler-(boiler water circulating pumps) - you need to deal somewhat with water chemistry-you need a condenser; that requires a source of cool water which requires a circulating pump(negative watts)- you need a feedwater pump(negative watts)- oil pumps for the turbine bearings(negative watts)-systems to feed fuel to the furnace(conveyor motors-(negative watts). All things considered you only get about 40% thermal effeciency from a "Rankin Cycle" boiler/furnace. You would burn too much fuel.

Why would you not heat the steam coming out of turbine and feedback to turbine?
becouse this steam is use repetdly for the turbine
How do fossil fuel burning plants work?
Simple breakdown of how Gas station works.Water is taken from a local river, this is then cleaned up, and given a neutral PH level. The gas is burned in what is known as a boiler. There are many tubes within the boiler which all carry the water. The water is heated to such an extent that it turns to steam, and we use this steam to turn what is known as a Turbine. The turbine on a Gas station would be a GT or Gas Turbine. This turbine is attached to what is Known as an AC generator. Similar to a car Alternator, but much larger. A generator turns Mechanical movement into Electricity through Electromagnets.This electricity is then put through a transformer which would step it up to around 132Kv, where it would then be fed to a consumer.WATER BOILER STEAM TURBINE GENERATOR ELECTRICTY
How much does a small steam turbine cost?
That would depend on the type and size of turbine.
What are the last 2 steps in an electrical power plant?
The last two steps are:The steam or gas spins the turbinesthe turbines then turns the electric generators producing elecricity
What are the three main sources of electricity?
My answer would be battery (or chemical), generator, and solar. Not sure what your context is. If you are asking about what's used in power plants, like coal, nuclear, and...I guess oil/natural gas would be the third, those are just different sources of heat to produce steam that turns a steam turbine. In all these cases it's still a generator.
How do geothermal power generate electricity?
Geothermal power plants work in one of two ways.One way is that they drill wells into a geothermal reservoir and extract steam to be used in a turbine. If the reservoir is not quite hot enough, they might have to extract hot water, and flash it into steam by lowering the pressure. In either case, this steam is run through a turbine, which turns a generator to generate electricity. The steam is usually condensed and either used in the plant or reinjected into the ground.The other way some plants work is by using the geothermal steam to heat water contained in a closed loop. This water is turned into steam, and runs the turbine. The steam from the ground would be condensed and reinjected. This has the advantage of keeping the geothermal steam separate from the power plant.Note that other than the source of the steam, a geothermal power plant operates in much the same way most other power plants work. Using steam to turn a turbine, which turns a generator is a very common method. Notable exceptions would be wind farms, solar cells, and hydropower dams, among others.

Where can I buy a steam powered generator?
The best place to purchase a steam powered generator would be online at www.greensteamengine.com. The website is very valuable to show the advantages of going with steam power.
Where are the requirements for steam turbine maintenance jobs?
To find out more about steam turbine maintenance jobs specifications one would be advised to contact specialists from recruitment agencies or job centers.
Where can I get a steam powered generator?
The best place to get a steam powered generator nowadays would be on Amazon.com/.ca. They may be a bit pricey, but they usually are a good investment.
Generator is moving 3000 RPM on 320Mw powerif full load rejected and any protection is not activate generator work as a motor what are damage possible?
depends on many things, including the type of prime mover (what is powering generator?). Presuming a steam turbine (or possibly combustion turbine though that's large for a single CT-gen) at that size and speed. "Rejection" of load is a term often misused. I'll presume correct use in this case, meaning that the generator remains connected to the grid, but for some reason has stopped producing power. If on the other hand what was meant was the generator was disconnected from the grid, it will not "motor". Upon rejection of load with no change in prime mover, the turbine would increase speed to a point where turbine over-speed protection would trip the prime mover to the turbine (fuel or steam), perhaps depending on design there may be some pre-emergency turbine controls to help reduce or control speed to below the trip point (perhaps about 110%, again depending on design). but if there is no controls that operate (including on turbine) turbine-generator unit may speed to point of damage (even destruction) as the centrifugal force of the higher speed exceeds design characteristics of the unit. Back to original question... If the generator rejected load due to loss of its field current, or either an open or short circuit in the generator, it likely will not motor. However, if the generator remains wholly intact and connected to the grid (meaning the reason for rejecting load is the loss or reduction of the prime mover to the driving turbine), the generator will motor. Possible generator damage could occur due to heating or pole piece shifting, depending on how sudden the change of phase angle (power flow) occurred. More likely, is (steam) turbine damage caused by overheating, most often starting with the lower pressure area blading. It is not uncommon to "motor" hydro electric generators operating either as a pump, or as a synchronous condenser for voltage or VAR control. But hydro-turbine-generators operate much slower RPM, with larger mass and damage is not incurred.
How do you make water energy frome eletrical energy?
This is how a Pressurized Water Reactor works. The water is at a high pressure to prevent boiling, and it is then hot enough to produce steam in a secondary circuit, to feed a steam turbine. spelt something wrong lmao =]
