Abstract
An efficient, high output, compact catalytic combustor that is low in combustion cost includes a combustion member having a front surface portion and a rear surface portion. The air-fuel mixture passing from the rear surface portion toward the front surface portion is combusted on the front surface portion. The combustion member is made of a material higher in thermal conductivity than alumina and includes a flame-holding unit for geometrically holding the flames formed on the surface of the combustion member. A catalyst oxide is carried on at least the front surface portion of the combustion member.
Claims6
A catalytic combustion element comprising:
- a combustion member having front and rear surface portions and made of a material higher in thermal conductivity than alumina, said combustion member including flame-holding mechanism and having an oxidation catalyst carried at least on said front surface portion,
- wherein said combustion member allows air-fuel mixture to pass from said rear surface portion to said front surface portion so that the air-fuel mixture can burn on said front surface portion, and
- wherein said flame holding mechanism is geometrically configured such that the air-fuel mixture collides with the flame-holding mechanism and causing a swirling flow of such mixture such that flames formed on said front surface portion of said combustion member are held thereon, and
- wherein said flame-holding mechanism and said front surface portion on which said oxidation catalysts is carried are integrally formed as a single body with said combustion member and surface portion unit.
A catalytic combustion element comprising:
- a combustion member having front and rear surface portions and made of a material higher in thermal conductivity than alumina said combustion member including flame-holding means and having an oxidation catalyst carried at least on said front surface portion,
- wherein said combustion member allows air-fuel mixture to pass from said rear surface portion to said front surface portion so that the air-fuel mixture can burn on said front surface portion, and
- wherein said flame holding means is geometrically configured such that the air-fuel mixture collides with the flame holding means causing a swirling flow of such mixture such that flames formed on said front surface portion of said combustion member are held thereon wherein said flame holding means comprise a plurality of ceramic wires wound into loops, and each ceramic wire is stretched in a plane by offsetting the loop centers thereof.
