Abstract (en)

[origin: US5871348A] A method and apparatus for preventing the accumulation of fines and the resulting formation of snowmen in a clinker cooler by applying short duration blasts of high pressure, high velocity air from openings in the cooler inlet grate. The cleaning air can be selectively supplied to a portion or portions of the cooler inlet grate. Monitoring may be provided to aid in the selective application of the cleaning air.
