3D visualization of the results of using modern OFA technology on the
example of real boiler

The leading place in the world for environmental protection is currently occupied by the protectionof the air basin. And the main sources of atmospheric pollution are industrial enterprises, motor transport andthermal power plants. Thus, there is an obvious need to increase attention to the problems of the innovationsector, mainly in the areas of technical improvement of heat and power industry enterprises. Therefore, thestudy of the problems of reducing the amount of harmful emissions into the atmosphere, control and regulationof its quality, as well as the study of new various methods of innovative development of thermal power is anurgent task at present, requiring a serious scientific approach. In the proposed work, computer experimentswere carried out in the field of innovative energy production technologies (the use of modern "sharp blast"OFA technology) at a specific thermal power facility of the enterprise of the Republic of Kazakhstan. Duringthe experiment, various ways of supplying additional air through OFA nozzles were investigated: OFA=0%(basic version without additional air supply), OFA=10% and OFA=18%. For these three modes, a comparativeanalysis of the aerodynamics of the furnace part of the boiler was performed according to the obtaineddistributions of the temperature and concentration fields of nitrogen oxide NO over the entire volume of thecombustion chamber. The results obtained were compared with experimental data obtained during experimentsconducted directly at the CHP.
