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 the use of a catalytic converter movable between an operative position where the flue gas flows through 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 does not flow through the catalyst when conditioning agent is no longer needed. The movable catalytic converter and related assembly may take variable configurations to accommodate various flue gas ductworks and space limitations.
