In recent years, there have been more and more projects using exhaust steam waste heat of units for heating. At present, there are two main technologies for using the exhaust steam waste heat of the wet cooling unit: the first is the heat pump heating technology, which uses the absorption or compression heat pump to extract the exhaust steam waste heat of the steam turbine and the high-quality energy. It also heats the circulating water of the heating network, which is characterized by flexible heating adjustment, but the investment is relatively large, and the increased heating capacity of the unit is small. The second is the high back pressure heating technology, which increases the back pressure of the wet-cooling unit, and directly absorbs the exhaust steam waste heat of the unit to heat the circulating water of the heating network through the condenser of the unit. It is characterized by less investment and difficult operation adjustment.
