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, to stabilize the flame of the gas burner and to improve performance. 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 screening plate(4) installed on one side of the burner support to contact one face with a gas fuel inlet hole of the rich combustion slit and the premixed lean combustion slit 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). Accordingly, the stability and uniformity of burner flame and a flame transition property are improved. Further, the entire performance of the burner is enhanced and combustion noises and pollutants are reduced.
