The invention discloses a head device of a combustion chamber, the combustion chamber and the gas turbine. The head device can be subjected to matching adjustment according to the axial dimensions ofa casing and a flame cylinder, the assembling needs are met, and the range of application is expanded. According to the head device of the combustion chamber, a first through hole is formed in the center of an end plate of a mixing cylinder of a head inlet piece; a second through hole and a third through hole which are symmetrical in the radial direction are formed in the near side cavity wall ofa gas collecting casing; a threaded hole is formed in the position, corresponding to the first through hole, of a flange, a fourth through hole is formed in the position, corresponding to the second through hole, of the flange, and a fifth through hole is formed in the position, corresponding to the third through hole, of the flange; and outer threads are arranged on a duty level fuel pipe, a mainlevel fuel pipe and an auxiliary support rod, the duty level fuel pipe is fixed to the flange by being connected with a thread of the threaded hole in a locking mode, the main level fuel pipe is fixed to the flange through a pair of first nuts located on two sides of the fourth through hole, and the auxiliary support rod is fixed to the flange through a pair of second nuts located on two sides ofthe fifth through hole.
Description
technical field [0001] The invention relates to the technical field of gas turbines, in particular to a head device of a combustion chamber, a combustion chamber and a gas turbine. Background technique [0002] Gas turbine is a high-power, high-performance power machine that uses air as the medium and relies on high-temperature gas to drive the turbine machine to continuously perform work. It is mainly composed of three major components: compressor, combustion chamber and turbine, together with intake, exhaust, control, transmission and other auxiliary systems. The thermodynamic cycle process of a gas turbine is as follows: [0003] The compressor continuously inhales air from the outside atmosphere and pressurizes it. The temperature rise of the compressed air is conducive to a more violent chemical reaction with the fuel, and a larger expansion ratio is also conducive to the release of a larger gas after the compressed air is burned. energy; [0004] After the compresse...
