Study on Heating ESP Ash Hopper with Hot Air from Air Preheater

The paper has designed a new method of hot air from air preheater heating electrical precipitator ash hopper. Firstly, the connection method of air preheater and ash hopper interlining has been drawn in design sketches. Then, through finding out the optimal design parameters such as diameter, flow velocity and temperature, the optimal scheme has been determined. It came to the conclusion that the new type of heating method has good feasibility and value of promotion.
