Discussion on the Importance of Water Vapor Chemical Supervision in Thermal Power Plant

Abstract

Water vapor chemical supervision is an important means to ensure the safe and economic operation of the unit, and is an important guarantee to ensure the qualified water quality of the power plant thermal system and the safe and economic operation of the unit. The water vapor system of the thermal power plant is very unstable, and it is easy to generate all kinds of oxides, sulfides, hydroxide and other solid impurities in the equipment, which will seriously affect the safe and economic operation of the unit. Therefore, strict chemical supervision of water vapor system is an important means to ensure the safety and economic operation of boiler and thermal equipment. In the power station boiler and thermal system, water and steam are heat exchange media. Due to the chemical reaction of water and steam in the thermal system, the metal equipment in the thermal system is corroded, so it is necessary to ensure the quality of water and steam through chemical supervision. Therefore, it is of great significance to establish a perfect water vapor chemical supervision system for the safe and economic operation of the power plant.
