Steam Power Stations - Arrangement and Working

Steam is produced in the boiler by utilizing the heat of coal combustion. The steam is then expanded in the prime mover (i.e., steam turbine) and is condensed in a condenser to be fed into the boiler again.. The steam turbine drives the alternator which converts the mechanical energy of the turbine into electrical energy. Although the steam power station simply involves the conversion of the

Combined Heat and Power: A Federal Manager's Resource Guide

Combined Heat and Power Combined Heat and Power (CHP), also known as cogenera-tion, is a system that efficiently generates electricity (or shaft pow-er) and takes advantage of the heat that is normally not used, to pro-duce steam, hot water, and/or chilled water. DOE has estimated that about seven percent of the total electrical power generation in this

generation, steam turbine CHP systems normally generate electricity as a byproduct of heat (steam) generation. A steam turbine requires a separate heat source and does not directly convert fuel to electric energy. The energy is transferred from the boiler to the turbine through high-pressure steam, which in turn powers the turbine and generator

The ratio of usable heat to power in a back-pressure steam turbine CHP plant is typically in the range of 3:1 to 10:1. This makes them unattractive for industries which have a high electricity but low heat demand. Figure 2 Elements of pass-out condensing steam turbine cycle. 1.2 Pass-Out Condensing Steam Turbines

A combined cycle (in which several thermodynamic cycles produce electricity), may also be used to extract heat using a heating system as condenser of the power plant's bottoming cycle.For example, the RU-25 MHD generator in Moscow heated a boiler for a conventional steam powerplant, whose condensate was then used for space heat. A more modern system might use a gas turbine powered …
