Multiple-tray settling chamber

Pollutant Loading-. Waste gas pollutant loadings can range from 20 to 4,500 grams per standard cubic meter (g/sm ) (9 to 1,970 grains per standard cubic foot (gr/sef)). Multiple-tray settling chambers can only handle inlet dust concentrations of less than approximately 2.3 g/sm (1.0 gr/sef) (Mycock, 1995 Parsons, 1999 Steinbach, 1999 Josephs, 1999). 

There are two primary types of settling chambers the expansion chamber and the multipletray chamber. In the expansion chamber, the velocity of the gas stream is significantly reduced as the gas expands in a large chamber. The reduction in velocity allows larger particles to settle out of the gas stream (EPA, 1982 Wark, 1981 Perry, 1984 Mycock, 1995 EPA, 1998). A multiple-tray settling chamber is an expansion chamber with a number of thin trays closely spaced within the chamber, which causes the gas to flow horizontally between them. While the gas...
