Combined Heat and Power – Technologies
A CHP plant consists essentially of an electrical generator combined with equipment for recovering and using the heat produced by that generator. The generator may be a prime mover such as a gas turbine or a reciprocating engine. Alternatively, it may consist of a steam turbine generating power from high- pressure steam produced in a boiler.
