Pressure Steam Turbine

The back pressure turbine refers to a steam turbine that has a higher exhaust pressure than the atmospheric pressure. As a kind of commonly used power plant equipment, this range of back pressure steam turbines can be used for driving water pump and draught fan, as well as the combined heat and power generation, such as the cases in public thermal power station, and the private power station in the petrochemical plant, metallurgy plant, chemical fertilizer company, sugar manufacturer, and papermaking industry.

QNP can provide both single-stage and multi-stage steam turbines. These back pressure turbines offer power ranging from 100KW to 50MW, and the working pressure can reach 14Mpa. So these steam turbines can be used in various industries for a variety of purposes. They feature easy operation and stable performance. Specifically, the single stage turbine is especially excellent for its simple structure, good adaptability, and easy installation. It is usually used for driving small power equipment like water pump for heating.
