Abstract: The soot formation and slagging characteristics of the heating surface of the boiler in garbage power plants were introduced, and the common soot cleaning mode and its application were described. Aiming at the problem of soot formation and slagging of the boiler heating surface in a garbage power plant in the Shenzhen, which causes the plant can not operate continuously in longer period, a technical reformation using the mechanical shaking combined with shock wave technology was carried out. The difficult problems of soot formation and slagging on the waste heat boiler heating surface tube platen of the plant and tube cracking caused by shaking, which puzzled the power plant for long time, were solved, and good reformation effect was obtained.

Key words: garbage power generation, heating surface of boiler, soot formation, slagging, soot cleaning device
