PURPOSE:To prevent the combustion chamber wall from being adhered with foreign matters such as fuel and the like by a method wherein the inner peripheral walls of cylindrical combustion chambers are formed with annular porous refractory bodies and combustion air is supplied in the annular chambers outside said refractory bodies. CONSTITUTION:The annular chambers 8-10 are made of the annular refractory bodies 6 and 7 with interconnecting minute voids with one another therewithin outside the cylindrical combustion chambers 1-3. Combustion air is jetted through a primary air supply pipe 39, the annular chamber 8 and the minute voids of the annular refractory body 6 into the combustion chamber 1. Said combustion air supplies oxygen necessary for continuation of combustion and as well as prevents the wall of the annular refractory body 6 from being adhered with foreign matters such as fuel and the like. |
