Micro-combustor

Patent Pending PROBLEM TO BE SOLVED: To provide a starting method of a micro-combustor capable of performing stable combustion by preventing blowoff phenomenon even when a flow velocity of a premixed gas is increased. ; SOLUTION: In this starting method of the micro-combustor wherein a premixed gas flow channel 13 and a combustion gas flow channel 14 are formed through heat transfer walls 18, 19, the premixed gas F is burnt in a combustion chamber 12, and preheating of the premixed gas F is performed by the heat of combustion gas E, a starting fuel S is supplied to a catalyst 21 placed in a combustor body, and then the premixed gas F is supplied into the combustor body.
