reheat turbine
Quick Summary
A reheat turbine is a type of steam turbine designed to increase efficiency. In a standard steam turbine, high-pressure steam partially expands, generating power. To improve efficiency, a reheat turbine returns this partially expanded steam to the steam generator to be reheated to its original temperature before it's fed back into the turbine for further expansion. This process is similar to reheating used in gas-turbine engines, where air is reheated after partial expansion to increase turbine output. Single reheat turbines are common in the electric utility industry, and double reheating may be used for very large units. Nonreheat turbines are typically found in industrial plants and smaller utilities.12
