The formation mechanism of nitrogen oxides in the combustion process of porous ceramic gas premix was discussed. The reason of low NOx emission during the combustion process was analyzed. Based on the temperature field of the mixed gas in the hole, the amount of nitrogen oxides generated in the combustion process was calculated by numerical method. At the same time, the nitrogen oxide emissions from the porous ceramic gas burner were obtained by experimental means and compared with the numerical results.
