Coolers and Kiln Hoods. Coolers receive hot material (clinker) discharged from the kiln and cool it as it is conveyed to handling and storage systems. To cool the clinker, ambient air is blown via fans up through the porous floor of the cooler. The service environment of the cooler is extremely abrasive, subject to wide swings in temperature ...
Total airflow required is (Q) = [10 (1ft)² + (0.087 ft²]100 ft/min = 1,009 cubic feet per minute. Example 2: The 4-inch diameter raw edged hood is now located six inches (0.5 feet) from the dust source and still needs to generate a capture velocity of 100 ft/min at the dust generation position to control the dust.
