the steam turbine is one kind of heat engine machine in which steam's heat energy is converted to mechanical work.the construction of steam turbine is very simple.there is no piston rod,flywheel or slide valves attached to the turbine.so maintenance is quite easy.it consists of a rotor and a set of rotating blades which are attached to a Pellet powered Steam BOILER for home or small business to run your electric meter backwards.Part 1 of a series.Home-PowerSystems.com The First Steam Turbine. The energy is transferred from the boiler to the steam turbine generator by an intermediate medium, typically steam under pressure. Most of U.S. and world electricity generation is from electric power plants that use a turbine to drive electricity generators. The electrical generating efficiency of standard steam turbine power plants varies from a high of 37% HHV4 for large, electric utility plants designed for the highest practical annual capacity factor, to under 10% HHV for small, simple plants which make electricity as a byproduct of delivering steam to processes or district heating systems. The steam turbine generator is the primary power conversion component of the electric power plant. I. This steam spins the blades continuously. the pressure builds and only allows the steam to flow to the od of the part and out the venturies.
