When traditional burners are not in use, external dust and debris can easily enter the burner through the openings on the combustion chamber, affecting the oxygen inlet holes on the inner wall of the burner, thereby affecting the effect of ultra-low nitrogen combustion in the burner. The soot generated during the ultra-low nitrogen combustion process will be adsorbed on the inner wall of the burner. If the dust is not cleaned in time, it will accumulate too much over a long period of time and easily erode and damage the inner wall of the burner, thereby affecting the service life of the inner wall of the burner.
