摘要： The combustion apparatus is composed of:
a porous burner component being made of a permeable metallic material and having a centrally located first region (10a,11aa,11ba,11ca) where the fuel-air mixture is ejected and the red heat condition is formed on the surface of downstream side and having a second region (10b,11ab,11bb,11cb) being located outside of the first region to recover heat from high temperature product gas coming from a combustion chamber, wherein the heat recovered in the second region is conducted to the first region; the combustion chamber (8) being located covering both the first region and the second region and enclosing these regions; a fuel-air mixture supply passage (7) to feed the fuel-air mixture into the central first region; and an exhaust passage (6) to lead the flue gas discharged from the second region to the exhaust opening (9), which exhaust passage is located adjacent to and outside of the fuel-air mixture supply passage and is separated by a separation wall (3) therefrom.
A combustion apparatus is further provided with a porous burner component having a third region (10c,11ac,11bc,11cc) through which the fuel-air mixture permeates, which third region is located at outside of the second region, and is provided with a peripheral fuel-air mixture supply passage (5) to lead the fuel-air mixture permeated through the third region into the central fuel-air mixture supply passage.
