Abstract

The invention relates to the field of fuel gas shock wave soot blowing, and discloses an oxyhydrogen shock wave soot blowing system capable of controlling soot blowing intensity. According to the relationship between the soot formation degree of soot formation heating surface and the surface temperature of the soot formation heating surface of a boiler, the ratio of oxyhydrogen in the mixed fuel gas and the opening and closing degree of a shock wave shoot jet orifice are regulated by utilizing a control device, thus the intensity of shock wave soot blowing is regulated, the operation of the shock wave soot blowing system is realized according to the actual soot formation degree of the heating surface, and the waste of oxyhydrogen fuel gas is avoided as well as the soot blowing effect is ensured.

Description

technical field [0001] The invention relates to the field of gas shock wave soot blowing, in particular to a hydrogen-oxygen shock wave soot blowing system capable of controlling the intensity of soot blowing. Background technique [0002] Sootblower is an indispensable and important auxiliary equipment for various waste heat boilers and power plant boilers. It plays a vital role in improving the heat exchange efficiency of each heating surface of the boiler, that is, increasing the output of the boiler. There are many types of soot blowers, such as steam soot blowers, sonic soot blowers, air shock wave soot blowers and gas shock wave soot blowers. Different types of soot blowers have different characteristics and scope of application, but among them The gas shock wave sootblower has many advantages that other types of sootblowers do not have, such as lower operating cost, greater sootblowing energy, stable sootblowing operation, less maintenance, and a wide range of applica...
