Abstract
A combustion control method for use in a catalytic combustion system having PA1 (a) a gaseous mixture inlet port, located at the upstream side of said catalytic combustion system, for the entrance of a fuel-air mixture; PA1 (b) an exhaust gas outlet port, located at the downstream side of said catalytic combustion system, for the exit of an exhaust gas; PA1 (c) a primary combustion chamber in which a catalyst body is disposed, said catalyst body being formed of a porous base material with numerous communicating holes that supports thereon an oxidation catalyst; PA1 (d) a secondary supply port, located downstream of said primary combustion chamber, for the supply of a gaseous mixture or air; and PA1 (e) a secondary combustion chamber located downstream of said secondary supply port; PA1 comprising such process that PA1 an excess air ratio of said primary combustion chamber is initially set above 1 and after the rate of combustion of said secondary combustion chamber exceeds a given level, combustion is made to take place, with the excess air ratio of said primary combustion chamber set below 1.
