Claims

[Claims for Utility Model Registration] 1. Having an annular inner cylinder and an outer cylinder, a combustion catalyst is disposed on the upstream side and in the inner cylinder, and is supplied inside the inner cylinder and between the inner cylinder and the outer cylinder. After one of the combustible mixtures is combusted by the combustion catalyst, the two are mixed and the combustible mixture for the combustion catalyst is fed to a catalytic burner downstream and supplied to the ceramic honeycomb disposed in the outer cylinder. In addition to installing a heater to preheat at startup,
A catalytic burner characterized in that it is provided with a high-temperature combustion means for burning the ceramic honeycomb at a high temperature during steady state. 2. The catalytic burner according to claim 1, wherein the high temperature combustion means is a system for recycling a part of the mixed gas generated by catalytic combustion. 3. The system is configured to return and supply a part of the mixed gas generated by catalytic combustion to the combustion catalyst disposed within the inner cylinder or between the inner cylinder and the outer cylinder using a circulation fan. Catalytic burner as described. 4. The catalytic burner according to claim 3, wherein the system has a circulating gas sleeve outside the inner cylinder. 5. The system is one in which an inner ventilary is provided in the inner cylinder.Claim 1 of Utility Model Registration
Catalytic burner as described in section. 6. The catalytic burner according to claim 2, wherein the system includes an outer ventilate that returns a part of the mixed gas generated by catalytic combustion to the combustible mixture supply line for the combustion catalyst using a ventilary mechanism. 7. Utility model registration claim 1, which is a system in which the high-temperature combustion means detects the temperature of the combustion catalyst, thereby controlling the heater on and off and changing the supply rate of the combustible mixture for the combustion catalyst.
Catalytic burner as described in section.
