Abstract: PURPOSE:To reduce a ratio of NOX and NO2 contained in NOX by a method wherein a combustion chamber is divided into a secondary air supplying zone and a combustion part, and a partition wall is composed of porous body. CONSTITUTION:A combustion chamber 5 is divided into a combustion part 6 and a secondary air supplying zone 7, a partition wall 8 is composed of porous body, thereby a diffusing combustion air is restricted in its concentrated supplying toward a flame 4 and further it is dispersed and supplied into the combustion chamber. In addition, the diffusing combustion air passing through the aeration holes of the porous body receives a heat from the porous body, is preheated and then supplied. That is, the supplying of the diffusing combustion air to the flame is dispersed and an amount of air to be supplied to the flame is also restricted, thereby a high temperature of the flame is prevented, a production of NO is reduced, the rapid cooling of the produced NO is prevented by preheating and dispersed supplying of air and then NO2 formation is also prevented. A rate of opening of the porous body is varied, thereby an effect of the combustion can be increased, and if the upper part is made large, a characteristic in lack of oxygen can be improved and a low rate of NOX can be attained.
