Analysis of Methods for Predicting Emissions of Harmful Substances in Liquid Hydrocarbon Fuel Combustion

Piecewise linear approximation on the basis of Delaunay triangulation is shown to perform excellently. This method completely eliminates negative concentrations on the resulting surface and shows the most favorable gradient distribution, with only 3.33 $$%$$ of gradients exceeding 75 ppm over the entire cloud surface. These results are significant due to the fact that this approximation method can generate highly reliable and physically accurate combustion maps. These maps are necessary for predicting critical emission levels (such as carbon monoxide (CO) and nitrogen oxides (NOx)) during the combustion of liquid hydrocarbon fuels, enabling the development of efficient burner optimization strategies to minimize environmental impacts and maximize combustion efficiency in practical power installations.
