Abstract
The present invention provides a flue gas conditioning system and method for generating conditioning agent used in the removal of entrained particles in a flue gas flow with an electrostatic precipitator. The invention involves a catalytic converter that is operable between an operative position where the flue gas is exposed to the catalyst and converts SO.sub.2 contained in the flue gas to SO.sub.3 when conditioning agent is needed and an inoperative position where the flue gas is not exposed to the catalyst when conditioning agent is no longer needed. The catalytic converter and related assembly may take variable configurations to accommodate various flue gas ductworks and space limitations and may carry one or more SO.sub.2 /SO.sub.3 converters providing a plurality of open and generally parallel flow paths of the flue gas.
