ABSTRACT:
Particulate emissions from a wood fire in a fireplace having a baffle for preventing the direct flow of fluid into the flue from the wood fire are reduced by locating a hydrocarbon gas pilot source in proximity to the baffle. Ignited gas from the pilot combines particulate emissions from the wood fire while they are in the fireplace and before they reach the flue. Air from outside of the fireplace is supplied into proximity with ignited pilot gas so the outside air and the ignited pilot gas mix. A flame sensor for the pilot controls the flow of gas to the pilot source and ignition of the pilot source.
