Pressure Steam - an overview ScienceDirect Topics

The advances in steam pressure and temperature led to the development of the reheat cycle, where steam is exhausted from the high-pressure turbine at reduced pressure and temperature and is then returned either to a section of the boiler or to a separate boiler to be reheated. Once reheated, the steam is sent to the low-pressure boiler.
