The purpose of the work is to improve the environmental characteristics of boilers of heat power plants, powerful boiler houses and industrial furnaces and to monitor their environmental conditions by: developing methods and measures to reduce the emission of nitrogen oxides by improving the thermo-gas dynamics of the combustion of pulverized coal and introducing an amine-containing reagent reductant; the use of eco-energy-efficient stabilizing burner devices; development of the scientific foundations of building computerized information-measuring systems and the creation of methods for remote monitoring of polluting substances of power plants. For a TPP 312 pulverized-coal boiler, typical of Ukraine's power system, using mathematical modeling methods, an estimate of the possibility of reducing nitrogen oxide emissions using thermo-gas-dynamic control of the coal combustion process and the reduction of nitrogen oxides using a chemical reagent was made and the corresponding recommendations were developed. The results of a comparative analysis of different options for staging the air supply are obtained and it is shown that the supply of secondary air through separate nozzles above the main burners reduces the generation of nitrogen oxides to 17%. The possibilities of using non-catalytic recovery of nitrogen oxides to improve the environmental characteristics of the TPP-312 boiler are investigated. For stabilizing burner devices with asymmetric fuel supply, oriented to use under conditions of relatively high values of the coefficient of excess air, the basic patterns of the flow of the various components of their working processes - flow, mixture formation of fuel and oxidizer, are established heat state of the combustion zone and fuel burnout. The effectiveness of applying various methods of influencing the characteristics of the proposed burners, such as the ratio of primary and secondary air flow rates, the location of the secondary air supply point, the geometric parameters of the fuel distribution system, etc. Scientific and practical principles for monitoring harmful emissions from heat power plants are developed, in particular, a method for predicting environmental parameters using a discrete Fourier transform is developed, which allows to increase the accuracy of measuring and predicting atmospheric air concentration by 3 times. Prototypes of modules for monitoring the air pollution monitoring system based on wireless sensor networks (mesh networks) with remote sensors and remote data transmission have been developed and tested.
