Three–dimensional mathematical modeling aerodynamics of the burner

Universal ecological energy–efficient burner was described. The burner allows burning different types of coal and lignite without the use of fuel oil for kindling the boiler. Efficiency assessment tools of the introduction of the burner for combustion of coal in modern thermal power plants were given.

Modern methods of preparation and combustion of coal in thermal power plants don’t completely meet the current requirements of reliability, environmental safety and economic efficiency of the boilers.

This fact raises the need to develop high–technology energy use of coal, aimed at a comprehensive solution to the problems of burning coals in a modern thermal power plant, namely the exclusion of the use of expensive fuel oil, fuel oil, reducing the nitrogen oxides reduction in slagging of heating surfaces of the boiler.

 The work deals with the aerodynamics of the universal energy–efficient burner device installed on the boiler BKZ–420–140 Krasnoyarsk RHPP–2. Applying the methods of three–dimensional mathematical modeling, studied coal particle separation process of various sizes in a muffle of the universal burner device and allowed the development of technical proposals to improve the efficiency of the burner.
