摘要：

This paper presents an experimental study of diffusion jet combustion of gas at different flow rates of CH4-N-2 and a constant flow rate of coal. Blow-off curves for a diffusion flame for different nozzle diameters are obtained. It is shown that an increase in the the nozzle diameter causes a decrease in the minimum residual flow rate of the fuel gas at which stable combustion is possible. As coal is supplied, the residual flow rate of the fuel gas also becomes slightly lower. The fluorescence of OH, which makes it possible to analyze the position and dynamics of the flame front is recorded.
