Abstract
Combined with real situation of air cooling units in Huadian Ningxia Lingwu Power Generation Co Ltd
the frost-cracking problem occurred in direct air cooling system under severe cold circumstances has been analysed
and counter measures for preventing frost-cracking being put forward.Through measures
such as retrofitting the structure of air cooling island
and adopting adjustment of the air flow rate under different environmental conditions in operation-optimizing process
the freezing problem occurred in operation of direct air cooling system can be effectively eliminated
thereby
the safe and economic operation level of air cooling units being enhanced.
