Abstract

PURPOSE:To reduce the cost of catalysts by mounting precious metal catalyst at the inlet side of combustion gas and metallic oxidizing catalyst at the lower stream side. CONSTITUTION:The catalysts 6 set up into a combustion cylinder 9 are divided into the first layer 6a and the second layer 6b toward the lower stream from the inlet side of the mixture 4 of air and fuel. The first layer 6a is formed by the precious metal catalysts having high activity at a low temperature, and the second layer 6b is formed by the metallic oxide catalysts in which the metallic oxide catalysts, which are far cheaper than the precious metal catalysts and which have activity at a high temperature, such as the metallic oxide of ferric oxide, cobalt oxide, nickel oxide, etc. or these mixture is carried to latticed or hoenycomb carriers with ventilating holes. Accordingly, the cost of the catalysts can be reduced.
