<P>PROBLEM TO BE SOLVED: To provide a micro-combustor capable of stabling flame in diffuse combustion in a micro-channel and capable of executing a large load operation. <P>SOLUTION: The micro-combustor has a combustion chamber 4 for executing combustion in the micro-channel by mixing fuel and oxidizing gas for combustion by diffusion, an oxidizing gas flow passage 6 for combustion for introducing the oxidizing gas for combustion into a combustion chamber, a combustion gas flow passage 8 for exhausting combustion gas from the combustion chamber and a heat transfer wall 10, formed between the oxidizing gas flow passage for combustion and the combustion gas flow passage, for recovering heat of the combustion gas and preheating the oxidizing gas for combustion. In the micro-combustor, a combustion part 2 where the micro-channel is formed with the oxidizing gas flow passage for combustion and the combustion gas flow passage spirally provided with the combustion chamber as the center, a fuel preheating chamber 5, provided parallel to the combustion part via a heat transfer panel 12, to recover the heat of the combustion part and preheat the fuel and a fuel supply part 3 having a combustion chamber supply hole 11 for supplying the fuel of the fuel preheating chamber to the combustion chamber. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
