ABSTRACT:
A fireplace afterburner is presented including a shell having a first open shell end for receiving fireplace emissions and a second open shell end for expelling fireplace emissions, a flue inside said shell having a first flue end which can be closed, and a second flue end which is open, wherein when the first flue end is closed fireplace emissions flow around said flue, and wherein when said first flue end is open fireplace emission flow through said flue, a heating element connected to said shell and encircling said flue, wherein said heating element heats emissions that pass in proximity to the element, and a catalyst bed connected to said shell and encircling said flue. A method for reducing products of incomplete combustion in fireplace emissions is presented including receiving fireplace emissions into a shell, heating said fireplace emissions to at least 1501° F. (816° C.), reacting said fireplace emissions with a catalyst substrate, and releasing the results of said reaction from said shell.
