LOW ENVIRONMENTAL POLLUTION AND HIGH EFFICIENCY RICH-LEAN COMBUSTION GAS BURNER FOR HOME BY USING POROUS KNITTED METAL FIBER MAT

摘要

PURPOSE: A rich-lean combustion gas burner for home is provided to reduce pollutants and to stabilize the flame of the gas burner. CONSTITUTION: A rich-lean combustion gas burner is comprised of a gas nozzle(2) for injecting fuel letting through a fuel supply hole; plural bunsen rich combustion slits(5) installed on a burner support(8) to let the injected gas; a premixed lean combustion slit(6) using a porous knitted metal fiber mat as a combustion surface material; a screen plate(4) installed on one side of the burner support to contact one face with a gas fuel inlet hole and prepared with a hole to let in gas fuel and first air from each gas nozzle; and an air charging plate(3) installed on a lower end of the burner support and prepared with plural air holes(31). Thereby, the discharge amount of pollutants is decreased and combustibility is enhanced by improving the stability of premixed lean combustion flame.
