Direct air condensing steam system uses air to condense steam directly into condensate water after work in low pressure cylinder of turbine, so as to complete one work cycle and enter the next work cycle. The direct air condensing steam system consists of several systems.
Direct air condensing steam system is the exhaust steam of the turbine is condensed directly by air, and the heat is exchanged between air and steam. The required cooling air is usually supplied by mechanical ventilation. The air condenser used in the direct air condensing steam system is composed of a large flat tube or a number of tube bundles with rectangular fins on the outer surface of the galvanized oval steel pipe. The air cooling system is characterized by large one-time investment and small operating water consumption.
