In order to ensure the safe and economical operation of the unit,the air leakage rate of the air preheater is controlled at a low level by proposing effective prevention and control methods.The engineering feasibility of the bimetallic self-compensating sealing technology scheme was analyzed from the aspects of working characteristics,modeling simulation and experimental verification,economic and social benefits.The results show that the scheme can effectively compensate for the triangular air leakage area caused by the"mushroom-shaped"deformation of the rotor of the air preheater,and provide a reference for the air leakage transformation of the air preheater.
