FIELD: heating. ^ SUBSTANCE: invention concerns thermal power industry, particularly methods and devices of gas fuel combustion in infrared burners. Method of gas fuel combustion in infrared irradiation burner involves preparation of homogenous gas fuel and air mix in ejector, mix heating in distribution chamber and in perforated ceramic nozzle channels to ignition temperature, burning on nozzle surface and in the space between nozzle and metal mesh, generation of stripped gas and air mix with air excess factor =1.3-1.5. Gas and air mix is tripped either by air supply to the burner ejector by fan, or by increasing rated gas pressure before burner in 6-7 times. ^ EFFECT: enhanced efficiency factor, reduced hazardous substance content in combustion products. ^ 4 cl, 3 dwg |
