ABSTRACT:
A mixture of an alkyl amine, e.g., tri-n-propylamine and an SO.sub.3 -containing acid, preferably, sulfamic acid is injected into the flue gas stream of a coal-fired utility boiler to reduce the electrical resistivity of the fly-ash particles and to increase their mean particle size, thereby improving their recovery by electrostatic precipitation or by mechanical separation, with consequent reduction in stack emissions.
