Reheat steam turbines are part of our special steam turbines, only providing simple copy for reference.

A regenerative steam turbine refers to a turbine where, in addition to the main steam entering through the main steam valve and regulating valve to impel the turbine blades and do work, there is also a path or multiple paths of low-pressure steam entering the turbine from a few stages behind, to further impel the turbine blades and do work.

Reheat steam turbines are widely used in self-generated power plants or small and medium-sized power stations in industries such as cement, chemical, petroleum, metallurgy, coking, and biomass energy, as well as waste incineration, effectively utilizing low-parameters energy like waste steam from production processes.

An example case is as follows:

A chemical plant has a steam turbine with a steam pressure of 0.98 MPa, temperature of 240°C, and flow rate of 3.5 t/h (up to 4.0 t/h) entering from the main and regulating valves. Besides, there's an additional low-pressure steam of 0.3 MPa, saturated steam, which enters a few stages behind the turbine to further impulse the turbine blades and generate power. This effectively utilizes both steam sources to increase electricity generation and improve efficiency.
