Method of conditioning exhaust gases from coal firing

Patent ·
OSTI ID:5550627
The present invention relates to operation of a rotary kiln plant utilizing electrostatic precipitators. Specifically, this invention is directed to a method for conditioning exhaust gases from a burning process in a rotary kiln in which mineral materials are treated by burning a fuel. The method comprises adding a water soluble alkali-metal compound to a solid fuel, at least part of which is a solid pulverized fuel, and then firing the fuel in the kiln plant, whereby the resistivity of the exhaust gases is less than about 10/sup 10/ ohm cm.
