factors that affect steam power plant boilers and turbines

Auxiliary Boiler - an overview | ScienceDirect Topics

Eric Jeffs, in Generating Power At High Efficiency, 2008. Mitsubishi uses an auxiliary boiler to provide cooling steam for the gas turbine start-up and there is therefore no change from air to steam cooling as the gas turbine runs up. The company has also experimented with steam-cooled rotor components and has tested rotors on their Takasago test plant, but the general view is that it is not

STEAM TURBINE - Thermopedia

The steam turbine is a turbine in which the potential energy of heated and compressed steam produced in a special device, a steam generator, or steam of natural origin (for example, from geothermal springs) is converted into kinetic energy (when the steam expands in the turbine blade cascades) and then into mechanical work on the rotating shaft.
