<p>PURPOSE: To preheat a catalyst up to a specified temperature at which a fuel gas is burnt when the fuel gas is placed in contact with the catalyst in a catalyst part and burnt and simplify a fuel gas combustion operation at the catalyst part and reduce the operation cost as well. CONSTITUTION: In a catalyst combustion device which introduces a fuel gas (a) to a catalyst area 12 by way of a gas in-flow passage 11 and places the fuel gas in contact with a catalyst in a catalyst part 12 and burns the fuel gas (a), a pre-combustion part 13 which preheats the catalyst part 12 by the above-mentioned fuel gas (a), is installed white a gas flow passage 15 is installed, which introduces the fuel gas (a) to the pre-combustion part 13 by way of the catalyst part 12.</p> |
