power plant boiler start and stop

Cold Starting /Warming Up/ Initial Starting and Stopping

Cold starting means starting off the boiler from a state of comparatively lower temperature and pressure than normal working values. In other way we can say that cold starting is starting the boiler for the first time in its lifespan.

Auxiliary Boiler - an overview | ScienceDirect Topics

One key feature of thermal CSP plants is that they are generally constructed as hybrid units, whereby an auxiliary boiler or other heating unit using natural gas, 1 can be used to heat the working fluid and power the generation system. With a relatively small additional capital expense, CSP plants are, therefore, capable of producing

Boiler (power generation) - Wikipedia

Haycock and wagon top boilers. For the first Newcomen engine of 1712, the boiler was little more than large brewer's kettle installed beneath the power cylinder. Because the engine's power was derived from the vacuum produced by condensation of the steam, the requirement was for large volumes of steam at very low pressure hardly more than 1 psi (6.9 kPa) The whole boiler was set into brickwork
