Abstract

In order to estimate the influence of various parameters of the nozzle on the premixed burner, the main technical parameters of the premixed burner nozzle were investigated by numerical simulation method. The factors including depth of the nozzle, back pressure of mixing chamber, outlet velocity were studied. By analyzing the case, the results show that the gas flow and velocity of different depth nozzles vary greatly, and the nozzle flow rate and the average speed of exit are all reduced with the mixing chamber pressure increased. In addition, the results show that the flow rate calculated by conventional method cannot reflect the actual situation of gas and air mixing.
