Abstract
Universal ecological energy-efficient burner was described. The burner allows to burn 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 do not 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 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 boiler [1].Fig. 1 shows a sketch of a universal ecological energy-efficient burner
Coal dust is supplied in the burner device; it is gasified at the excess air coefficient which is significantly less than unity
Summary
Modern methods of preparation and combustion of coal in thermal power plants do not completely meet the current requirements of reliability, environmental safety and economic efficiency of the boilers.
