Abstract
Currently, ANSYS Fluent software is widely used as an alternative engineering tool for describing the physical processes that occur in boiler furnaces and burners.Studies of the fuel preparation and combustion characteristics in the KVTK-100-150-4 boiler using the ANSYS Fluent program were performed.The characteristics of the combustion process in the combustion chamber were calculated.The analysis of methods for reducing the pollutant formation showed the rationality of using staged combustion to reduce NOx emissions.The performance of the proposed modeling method in MATLAB was demonstrated by using Type I and Type II error functions, followed by higher statistical performance such as error variance and correlation analysis.A comparative analysis was carried out to substantiate the superiority of the proposed modeling technique.
