Abstract

The method of water decontamination of thermal power plant heating surfaces in the process of slag-forming fuel burning has been considered. The consequences of ash and slag formation, their influence on the boiler unit operation and the methods of elimination have been revealed. The blast by steam and water is the main and the most common cleaning method. Despite a large number of domestic water blowers, the most part of designs has some parameters requiring their technical level improving. In order to increase the technical level of produced blowers, JSC «Krasnoyarsk machine-building plant» studies the design weaknesses based on the comments and suggestions of operation organizations. The research done allow to find out the main design parameters which can determine the reliability and efficiency of long-range water decontamination. The parameters that were defined make it possible to minimize mass, dimensions and energy consumption of the blower. As a result of the research, a new and improved KMZE027 long-range water blower has been developed. In terms of technical specifications, it is a highly competitive machine with a foreign SMART CANNON blower by Clyde-Bergemann. Some calculations have been carried out and influence dependencies of the nozzle device design and pressure on the jet formation have been determined. The new blower is an import-substituting product. The materials and devices of domestic production are used in its design
