Product Description

　　The Y50 turbine is a multi-stage condensing extraction steam turbine. Its flow path comprises two double-row velocity stages and seven pressure stages. As a modular turbine, the actual number of stages used depends on the turbine’s output power, rated speed, inlet steam pressure, and temperature. The turbine is optimally designed to ensure high efficiency in delivering its rated power.

　　The steam turbine operates at a speed of 3,000 r/min, with an output power range of 3,000 to 6,000 kW. The governing system adopts an electro-hydraulic regulation mode (either the WOODWARD 505E controller plus CPCⅱ electro-hydraulic transducer or the domestically produced DEH electro-hydraulic regulation system), featuring multi-valve nozzle control arranged in a double-layer configuration. The Y50 series turbines are multi-stage condensing extraction turbines. The unit’s industrial steam extraction rate and the user’s electrical load can be adjusted independently according to user requirements, thereby enhancing system efficiency. The turbine-generator set can also operate under pure condensing conditions (with zero industrial steam extraction), making it suitable for a wide range of applications.
