ABSTRACT:
A gas turbine combustion apparatus has a plurality of combustors provided in a circumferential direction within a turbine casing chamber formed by a casing, each combustor comprising a combustor inner tube and a combustor transition pipe, but lacks a turbine bypass mechanism for controlling the amount of compressed air discharged from a compressor into the turbine casing chamber. The combustion apparatus comprises an exhaust port member fitted into a manhole opening in the casing and communicating with the outside of the turbine casing chamber, bleeding pipes for uniformly bleeding compressed air discharged into the turbine casing chamber, a circular pipe for recovering compressed air bled by the bleeding pipes and discharging the compressed air to the exhaust port member, and an opening and closing valve for controlling the amount of exhaust which the circular pipe discharges to the outside of the turbine casing chamber via the exhaust port member, thereby possessing a turbine bypass mechanism.
