Engineering Procurement Construction
Thermal power plant covers several different types, such as full condensing, single-extraction (steam extraction with one certain temperature/pressure), double-extraction (steam extraction with two kinds of temperature/pressure), back pressure (make use of the exhaust steam) and combined type (extraction and back pressure), to meet the different kinds of requirement of the owner. Usually the power plant of extraction type and back pressure type be named as "Cogen plant", because they produce not only electricity but also steam (external supply). Cogen plant and full condensing power plant are both widely used, mainly for electricity supply to state grid as well as electricity / steam supply to some certain enterprises.
