PURPOSE: To provide a catalytic burning method wherein the thermal problems of a catalyst are avoided by lowering the combustion temperature of the catalytic part, and the emission of air pollutant is controlled and obtain a high thermal efficiency by employing the aforesaid method in the combustion apparatus such as boiler and combustion furnace.
CONSTITUTION: A catalytic burning method comprises supplying a premixed gas adjusted to an air ratio of less than one to a catalytic reaction part C with a catalyst 12, generating the partially reactive gases containing the combustible components such as HC hydrocarbon, CO and H2 from the fuel in the premixed gas by the action of the catalyst 12 of the catalytic reaction part C and introducing the partially reactive gases into a flame burning part F with a secondary air introducing means A, whereby a secondary air is introduced into the partially reactive gases from the catalytic reaction part C by the secondary air introducing means A to effect the flame burning. The aforesaid method further comprises setting a total of the amounts of the air in the premixed gas and of the secondary air and the amount of fuel in the premixed gas at an air ratio of at most 1.5.
