MICRO GAS TURBINE INCLUDING IGNITOR COMBINATION STRUCTURE AND METHOD FOR ASSEMBLING THE SAME

摘要

PURPOSE: A micro gas turbine having a structure for coupling an igniter and an assembling method thereof are provided to thread-couple an igniter flange and a coupling member by rotating an igniter assembly in order to seal a gap between a liner casing and the igniter flange, thereby preventing the leakage of mixture gas of compressed air and fuel. CONSTITUTION: A micro gas turbine having a structure for coupling an igniter includes an igniter(121), an igniter flange(122), a coupling member(124), and a bellows(140). The coupling member has a first part(124a) inserted inside a liner casing and a second part(124b) curved against the first part and mounted on the liner casing. The bellows is stuck to the second part. The igniter is coupled to one side of the igniter flange. A circumferential groove(128) is formed on the other side of the igniter flange so that a space part can be formed between the igniter flange and the coupling member.
