Abstract
This study is aimed at improving environmental efficiency by establishing the dependence of the parameters of optimal combustion of liquid hydrocarbon fuels (diesel fuel, crude oil, fuel oil, kerosene, waste oil) on their physical properties using steam atomization with superheated steam. The methodology includes the construction of regime maps of CO concentration with approximation by radial basis functions and smoothing by a median filter. During the study, a statistically significant linear relationship between the angular coefficients of the optimal regime equations and the Laplace number (r = 0.834, R2 = 0.7) was established. Based on the obtained dependences, an equation is proposed to calculate the optimal flow rate of superheated steam depending on the Laplace number for the optimal combustion mode of liquid hydrocarbon fuels in an atmospheric burner with steam atomization and a gasification chamber to reduce emissions of harmful substances.
