Embodiment Construction

[0030] The overall structure of the present invention is shown in Figure 1, a return-type annular tube combustion chamber composed of an intake casing 1, an inlet adjustable guide vane 2, a multi-stage axial flow compressor 3, a diffuser 8, and a plurality of flame tubes 9. The multi-stage axial flow turbine 10 and the exhaust casing 11 are composed of main components. The inner and outer casings of the intake casing 1 are integrally cast with 19 force-bearing rectifying support plates, and the casings of each component are connected by axial bolts. The compressor 3 and the turbine 10 are both disc-drum structures. In the meantime, they are tightly connected by axial bolts and form a drum-type compressor-turbine rotor, which is supported on two sliding flat bearings at the front and rear, showing a double-support and single-rotor structure.

[0031] The compressor 3 of the present invention is shown in FIG. 2 .

[0032] It consists of a compressor stator (28) and a compressor...

Abstract

The heavy gas turbine consists of air admission casing, air admission adjustable guide vane, air pump, diffusor, combustor, turbine and air exhaust casing. The air admission casing has inner casing and outer casing cast integrally with the commuting support plate, and the casings for different parts are connected via axial screw bolts. The air pump and turbine rotor are in disc-drum structure connected firmly via axial screw bolts to constitute drum type air pump-turbine rotor, which is supported on front and back sliding plain bearings to form a double-support and single-stator structure with front output shaft connected via elastic coupling to the generator. The present invention has air pump with high compression ratio, combustor with low pollution exhaust, multi-stage air-cooled turbine capable of bearing high burning gas temperature and relatively light complete machine.

Description

technical field [0001] The invention belongs to the technical field of power machinery, and in particular relates to a power device for a gas turbine generating set. Background technique [0002] Existing heavy-duty gas turbines are all composed of compressor, combustion chamber, turbine plus intake and exhaust casings. To design and manufacture a good heavy-duty gas turbine, all main components are required to have high performance and stable working range. The compressor is required to have a high boost ratio, high compressor efficiency, especially a high stage boost ratio, and a certain stable working margin; the combustion chamber is required to be When the parameters are changed, it will not cause too lean combustion to affect the combustion stability and combustion completeness, and it cannot be allowed that under certain conditions, the combustion leanness is not enough to increase the NOx content in the gas emissions. Therefore, the combustion chamber is required to...
