Reasons and Solutions for Air Preheater Blockage in 300 MW Coal-fired Power Plant
With the proposal of the"dual carbon"goal,peak shaving of thermal power plants in the power grid has become particularly important.Air preheater is one of the main equipment of boilers in thermal power plants,and the load capacity and stability of the unit largely depend on the stability of air preheater.The blockage of air preheater causing a high primary air pressure difference will directly affect the safe and stable operation of the boiler.This paper focuses on analyzing the phenomenon of blockage in the air preheater of a power plant,which is caused by the scaling of ammonium bisulfate and the measures taken to solve the problem of blockage in the air preheater.
