Zusammenfassung: | The utility model provides an indirect air cooling system for a supercritical unit or an ultra-supercritical unit. The indirect air cooling system comprises a steel spraying condenser, a circulating water pump set, a steel radiator, a hydraulic turbine and a water-supply system, wherein, the steel spraying condenser is used for leading exhaust steam to be in direct contact with cooling water for mixing so as to achieve heat exchange; the circulating water pump set is used for boosting heated cooling water so as to obtain boosted cooling water; the steel radiator is used for cooling the boosted cooling water through heat convection between the boosted cooling water and air so as to obtain the cooling water; the hydraulic turbine is used for regulating the pressure of the cooling water and recovering the energy at the same time when the cooling water is conveyed to the steel spraying condenser; in addition, the water-supply system adopts alkaline water working condition operation, is connected with the steel sp |
