This work focuses on modeling sections of a subcritical coal-fired power plant and proposes algorithms for fault detection in MATLAB/Simulink. The developed model simulates the process dynamics including steam and feedwater flow regulating valves, drum-boiler, and heat rate on the regulation of pressure, drum level and production of saturated

2020-11-3 · WHAT IS A SUPERCRITICAL BOILER? Supercritical steam generators (also known as Benson boilers) are frequently used for the production of electric power. In contrast to a "subcritical boiler", a supercritical steam generator operates at such a high pressure (over 3,200 psi/22.06 MPa 3,200 psi/220.6 bar that actual boiling ceases to occur, and the

For example, for typical "low-sulphur" coal containing 0.5 per cent of sulphur when fed into the boiler, every tonne of coal will contain 5 kilograms of sulphur. When burnt, this sulphur turns
