Adaptive Fuzzy PID Control Applied in Boiler System

The boiler system in power plant consists mainly of a steam-water system and combustion system, which produce a high-pressure superheated steam to drive a generator in order to produce power. The steam temperature control of the boiler system is a critical operational consideration. Parameters of boiler producing process must be controlled strictly.

Effect of Coordinated Air Pollution Control Devices in

2017-7-20·An arsenic emission study was performed at nine coal-fired power plants in China and the U.S. that are equipped with various air pollution control devices (APCDs). On average, over 90% of arsenic in the flue gas is captured by the dry particulate matter collection system. Less than 3% of arsenic remains in the boiler slag, and 3% is captured by the desulfurization system.
