Steam-electric power station - Wikipedia

The steam-electric power station is a power station in which the electric generator is steam driven. Water is heated, turns into steam and spins a steam turbine which drives an electrical generator. After it passes through the turbine, the steam is condensed in a condenser. The greatest variation in the design of steam-electric power plants is

Reheat Steam Cycle - an overview | ScienceDirect Topics

Eric Jeffs, in Generating Power At High Efficiency, 2008. In a normal three-pressure reheat steam cycle the intermediate-pressure output of the heat recovery boiler joins the returning cold reheat line from the steam turbine and the combined flow goes through the reheater. At low loads, below 20%, there is no steam flow through the transition

The History of the Steam-Generating Boiler and Industry

In response to this need, the package or shop-assembled boilers were developed. A package boiler is a pre-engineered steam-generating boiler that ranges in size and steam capacity (typically from 10,000 to 600,000 lb/hr) built in a shop and shipped by rail or barge. Many companies manufactured these small shop-assembled boilers.
