摘要： The combustion apparatus having a heat-recirculating function comprises: a porous burner component (4) being made of permeable metallic material and having a first region (4a) through which a fuel-air mixture flows and is ejected therefrom into the combustion chamber at a velocity higher than the burning velocity of the fuel-air mixture to form a flame base on the periphery of the fuel-air mixture ejection area and having a second region (4b) being located adjacent to and outside of the first region to recover heat from high temperature product gas generated from the combustion of the fuel-air mixture by red-heating the surface of the second region on the combustion chamber side while the product gas is penetrating through the burner component (4), wherein the heat recovered in the second region is conducted to the first region; the combustion chamber (5) being located to cover both the first region (4a) and the second region (4b) and enclosing these regions, and a cylindrical wall (6) separating a fuel-air mixture supply passage (9) from a product gas exhaust passage (10) by placing the fuel-air mixture supply passage at the inside thereof. Such a combustion apparatus having a heat-recirculating function comprises: a porous burner component (4) having more than one first region (4a) and more than one second region (4b); a combustion chamber (5); and more than one cylindrical wall (6).
