Hood for emission control for fireplace

Abstract

A hood for directing smoke from a wood burning fireplace through a filter or catalytic converter enables a substantial reduction in pollutants released to the environment. In an exemplary embodiment, a hood includes a housing, in which an exhaust cleaner support unit supports an exhaust cleaner for reducing pollutants as smoke is directed from an intake opening of the housing to an exhaust opening of the housing. A rear surface of the housing and side surfaces of the housing abut three walls of the fireplace, reducing air paths behind or beside the hood to capture a substantial amount of the smoke from the fire. The front of the hood is tapered to direct the smoke toward the exhaust cleaner. Due to a mild suction effect from heating of the exhaust cleaner, the front surface of the hood need not extend all the way to the front of the fireplace, and air flow in front of the hood into the flue is not impeded.
