摘要:
The invention relates to a fume box having a separation partition (16) in the upper portion thereof that comprises a removable catalyst block (17) offset relative to the inlet (10) and the outlet (8), and an intake passage that can be blocked by at least one insulating block. Deflectors slow down the gases and fumes and protect the catalyst block against falling soot and particle. The invention is particularly intended for manufacturers of domestic combustion heating appliances, in particular those using wood.
摘要:
A hybrid wood-burning fireplace assembly configured for burning wood-based fuel, wherein the burning generates combustion exhaust. The assembly comprising a fire box having an interior area, a baffle in the interior area defining lower and upper combustion chambers relative to the baffle. The upper combustion chamber has an upper exhaust passageway between baffle and the top portion of the firebox. A secondary combustion airway has air outlets in the firebox that direct the secondary combustion air adjacent to the baffle to mix with the exhaust for non-catalytic secondary combustion of the exhaust before the exhaust flows through the upper exhaust passageway. A catalytic combustion unit is positioned above the baffle and across the upper exhaust passageway, whereby the exhaust will pass through the catalytic combustion unit after the non-catalytic secondary combustion of the exhaust and before the exhaust exits the upper combustion chamber through the upper exhaust passageway.
摘要:
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.
摘要:
Pollutants in air or other fluids are converted to harmless compounds by positioning a catalyst coated reticulated foam in the path of the fluid flow. The reticulated foam is a three dimensional latticework of interconnected ligaments forming a porous, open-celled structure with a large internal surface area. Internal surfaces of the reticulated foam are coated with the catalyst. Catalytic conversion efficiency is maintained by fluid heat, an internal heating source, or external sources, such as combustion processes and radiation illumination.
摘要:
A gas-fueled heating appliance having a system for reducing the amount of undesirable combustion products released to the site in which the appliance is installed. The appliance includes a firebox partially surrounded by a heat exchanger. Ambient air is drawn into the heat exchanger below the firebox and a portion of the ambient air enters the firebox to assist in combustion, and the remaining portion travels through the heat exchanger to be heated by convection before being combined with combustion gases exiting through the top of the firebox. The heat exchanger creates a low pressure area relative to the firebox which induces a draft from the firebox into the heat exchanger and ultimately to the ambient environment through an exit provided above the firebox. A carbon monoxide catalyst element is provided in the exit passageway from the firebox to the heat exchanger to oxidize carbon monoxide into carbon dioxide and filter away airborne particulates which would otherwise be released to the ambient air.

摘要:
This invention relates to heating apparatus and particularly compact heating apparatus fuelled by a flammable fluid such as gas in which a visible flame is provided. The appearance of the visible flame and the fireplace setting within the heating apparatus is enhanced by the provision of a reflective means positioned behind the fuel assembly to reflect an image of the assembly and/or the flame towards a viewing port in the front of the heater. Additionally or alternatively, the heater apparatus provides an exhausting of the emissions of the primary combustion directly into the room in which the heater is housed to return much of the otherwise exhausted heat into the room. The exhaust is put through a secondary combustion chamber including or comprising a catalytic converter before being exhausted into the room.
