PURPOSE:To contrive lowering of NOx, by providing a combustion plate which is made to burn on its surface and is made of a porous sintered body is provided on an opening part of a mixing chamber. CONSTITUTION:A combustion plate 9 which is a hollow and almost conical shape and is provided on an opening part of the upper part of an evaporating cylinder 6 together with the evaporating cylinder 6, a heater 7 and a throttle plate 8 constitute a combustor 5. The combustion plate 9 is formed of a porous sintered body, such as a ceramic body like a hardened sponge, and very small and complicated labyrinthine ventilating holes are provided as openings for flame from the surface of a mixing chamber side to the external surface. By this constitution a contact area between a flame and the combustion plate 9 is increased and reduction of NOx is contrived. |
