Two direct air-cooled condenser(ACC) units with air temperature monitoring system for a 600 MW level unit were taken as objects to build the 3 dimensional numerical models and simulate the distribution of air temperature and velocity at outlet of the condensers
after ash deposition and speed regulation of fans for the deposited unit.Results show that
the air temperature and velocity at outlet of the finned tube for ACC in ash deposited area are lower than that in clean zones.Locally regulating fans in high temperature area by the air temperature monitoring system at outlet of the ACC
can efficiently improve the heat exchange behavior of ash deposited areas.
