Abstract
Improved apparatus and methods for the treatment of boiler flue gas with sulfur trioxide conditioning agent include the beneficial use of catalytic converters that can be located immediately adjacent the injection site for their sulfur trioxide output, that can be individually sized and manufactured for variable required conditioning agent outputs, that can be individually controlled and can provide substantially improved conversion efficiency and that can provide an efficient, flexible, effective and relatively inexpensive multi-boiler flue conditioning system.
