Extraction Condensing Steam Turbine

The power range of extraction condensing turbine is from 1500kW to 12000kW, when the power not exceed 3000kW, turbine will provide a reduction gearbox; the power exceed 6000kWh or greater, turbine will connect with a generator directly.

The turbine is single casing, single shaft, impulse type and has a controlled retraction of one stage. The extraction flow and power load may be automatically adjusted in accordance with the user requirements, also pure condensing condition operating may be allowed.

This series unit consists of a rotor and stator. The rotor is assembled. The stator includes a casing, nozzle and diaphragm, labyrinth gland and bearing etc. A governing valve of HP casing and MP casing is connected with an actuator of speed regulation system via a mechanical lever.

A governing system of unit is full hydraulic; it provides the automatic regulation device of extraction, protection devices and monitoring instruments.
