The premixed burner null premixed burner in order to execute the manner and this manner in order to raise the hydraulics stability

摘要

PROBLEM TO BE SOLVED: To suppress a wrong movement vortex to form interference pressure vibration structure effectively and without additional energy consumption by improving a method for hydrodynamic stabilization of a premixture burner used to stabilize a flame during operation of the burner by guiding at least one combustion air flow 5 in a tangential direction in a burner hollow chamber 5, mixing with sprayed gaseous and/or liquid-form fuel 7; 8 while forming a torsional flow 9 situated coaxially with a burner axis 4, generating a reverse flow zone 15 in the section drastic change spot of a burner opening 14 and using the reverse flow zone to stabilize flame during operation of a burner.;SOLUTION: The torsional flow 9 is gradually widely increased in a burner hollow chamber 6 toward the burner opening 14 and penetrated in a combustion chamber at a non-rotational symmetrical flow sectional surface. In this case, deformation is generated in sacrifice of a free flow sectional surface 18.;COPYRIGHT: (C)2002,JPO
