COMBUSTOR OF A GAS TURBINE CAPABLE OF INCREASING THE AMOUNT OF AIR FLOWING IN A FLAME AREA BY REDUCING THE AMOUNT OF AIR FLOWING IN AN AIR PASSAGE

摘要

PURPOSE: A combustor of a gas turbine is provided to let an inserting unit control the amount of air inflow with thermal expansion, thereby increasing flame stability.;CONSTITUTION: A combustor of a gas turbine comprises a liner (130), an outer tube (140) and a transition piece (150). The outer tube is arranged outside the liner. The outer tube comprises an air passage (135) formed between the outer tube and the liner. The transition piece is separately located to form the air passage between the transition piece and the liner. The transition piece includes an insertion unit (152) which enables the transition piece to relatively move in the end of the outer tube. The insertion unit controls the amount of an air inflow with thermal expansion. The insertion unit comprises a sloping unit which is slanted towards the end of the liner. The sloping unit is slanted towards the outer tube so that the air passage becomes narrow during thermal expansion.;COPYRIGHT KIPO 2013
