Description

Overview
1. Siemens SGT-400 gas turbine operation
2. The SGT-400 is a twin-shaft, simple open-cycle, non-regenerative industrial gas turbine designed for power generation and mechanical transmission.
3. Our company's SGT-400 gas turbine generator set is the first domestic coke oven gas as fuel generator set, after the fuel is fully burned, the high temperature and high pressure gas expansion is generated to do work, promote the power turbine to rotate at high speed, after the independent planetary reduction device changes, the generator is connected through the coupling, and the generator is driven to generate power generation device.
4. On June 18, 2015, the two units were put into operation one after another.
5. In 2019, after the exchange method of overhaul, unit was put into operation again.
6. As to November 27, 2020, the unit has stable operation and good condition.
7. In response to the national environmental protection requirements, it has actively stopped so far, and regularly maintained.
Gas Turbine
1. Model SGT-400
2. Form: simple open cycle, single axis, hot junction output
3. Rotor rotation direction counterclockwise (from the output)
4. Air intake device: the intake volute mounted towards the front housing and the outer cavity of the front bearing housing form the intake tract
5. Compressor: 11-stage axial subsonic speed, imported transducible vanes, rated speed 4100 rpm
6. Combustion chamber: 6 reflux tubular combustion chambers, each with 1 high-energy igniter
7. Turbine: 2-stage compressor turbine (CT), 2-stage power turbine (PT)
8. Bearings: 4 tilt pad radial plain bearings, 2 axial thrust bearings
9. Exhaust device: diffusion section and horizontally mounted exhaust volute

Gearbox and Coupling
1. Gearbox: independent planetary reduction device, the output speed after deceleration is 1500 r/min. From the output end, it rotates the power shaft counterclockwise to clockwise. With a weight of 4030 kg, it is the benchmark for the installation and positioning of gas turbines and generators.
2. High-speed coupling: gear-type coupling, which couples the power turbine output shaft adapter with the solar pinion of the gearbox with a bolt connection.
3. Low-speed coupling: Rao metal disc type, the gearbox output shaft and the generator output shaft are connected and coupled.
Generator
1. Model QFR-15-4
2. Form: brushless excitation three-phase synchronous generator
3. Rated speed: 1500 r/min, cooling method: air water cooling
4. Degree of protection: IP54, insulation class: F/F
5. Rated voltage: 10500 V, rated current: 1031 A
6. Rated power: 15000 kW, power factor lag: 0.8
7. Delicate deflection: 0.148 mm, noise level: not greater than 85 dB
8. Direction of rotation: counterclockwise (from the gas engine end)
9. Flywheel torque (GD²): 7750 kg·m²
10. Main generator air gap: 20 mm
11. The total weight of the motor is 45 t
12. Rated excitation voltage: 98 V
13. Rated excitation current: 8.7 A
