Common auxiliary steam pressure control: Here the steam header pressure is measured in one of two modes and compared with a fixed set point. The deviation this creates is used to drive a PI controller. The output of the controller, through two sets of A/M stations and I/P converters, can regulate the pressure-reducing valves in MS and CRH lines to maintain constant pressure at the common

Coal-fired power station - Wikipedia

A coal-fired power station is a type of fossil fuel power station.The coal is usually pulverized and then burned in a pulverized coal-fired boiler.The furnace heat converts boiler water to steam, which is then used to spin turbines that turn generators.Thus chemical energy stored in coal is converted successively into thermal energy, mechanical energy and, finally, electrical energy.

Steam power stations with pressure-fired boilers (Journal

Steam power stations with pressure-fired boilers are suitable for medium-load and base-load installations. Their advantage over conventional steam power stations lies in the small amount of space required, the lower boiler losses and the more favorable price. Authors: Pfenninger, H; Yannakopoulos, G.
