Product Description
The C570 steam turbine is a single-stage back-pressure steam turbine generator set featuring a single-speed-recovery-stage rotor with a pitch circle diameter of 1040 mm. Its speed control system employs the internationally mainstream American
Woodward 505 digital controller + CPC electro-hydraulic converter, multi-combination valve regulation, forced lubrication, and a main shaft speed of 3000 rpm, paired with a high-voltage generator. The primary feature of this model is its utilization of low-temperature, low-pressure steam with a small pressure differential as the steam source to drive the steam turbine generator for electricity generation. Its maximum power output reaches 3000 kW. This type of turbine unit is a first in China.
pioneering in China. Deployed in thermal power plants, it utilizes steam supplied by district heating plants at pressures of 0.8-1.2MPa to drive the turbine. Exhaust steam at 0.2-0.7MPa is then directed to heat users'
production workshops, simultaneously ensuring process steam supply and generating electricity from the pressure differential—delivering significant economic benefits.
Structural Features
