ABSTRACT:
The present invention pertains to a method for nitrogen oxide reduction and flue gas reheating wherein a catalyst surface is heated to an operating temperature to facilitate a catalytic reduction reaction in the presence of relatively cool flue gas. To avoid conventional complication the catalytic reduction reaction is performed downstream of both particulate control operations and desulfurization procedures. That is, the catalyst surface itself is placed just before the stack. The method of the present invention reheats the flue gas prior to its exit into the atmosphere.
