Back Pressure Turbine

Back-pressure steam turbines utilize the pressure difference between the inlet and the outlet steam to efficiently convert a portion of the thermal energy of the steam into mechanical energy for further utilization. The exhaust pressure is designed to be higher than the atmospheric pressure, so that the thermal energy of the exhaust steam can be reutilized in a variety of industrial processes.
