It is a common problem that the direct air-cooled unit cannot be fully charged during the high temperature period in summer
and the widely used solution is to install a sprinkler device in the air-cooled unit for humidification and cooling. Through analysis on the air flow field in the cooling unit
it is found that the air flow field in the silo is non-uniform due to the influence of fans and bridges. The method of non-uniform arrangement of nozzles in the air flow field is used to evenly mix the air and spray water
and the high-pressure spray is used to achieve a uniform temperature drop in the overall air field to minimize the temperature of the cooling air. This method effectively solves the problem of cooling and improves the efficiency of air-cooled units in summer
and is of great significance for peak operation of thermal power units in summer.
