A supplementary steam turbine refers to a turbine where, in addition to the main steam entering through the main steam valve and regulating valve to drive the turbine blades, one or more streams of low-pressure steam also enter the turbine through the rear stages to drive the turbine blades.
Reheat steam turbines are widely used in self-owned power plants or small-to-medium-sized power plants within industries such as cement, chemical, petroleum, metallurgy, coking, biomass energy, and waste incineration. They effectively utilize low-parameter energy sources like waste steam generated during production processes.
