Scrubber for Outdoor Furnace, Stoves & Fireplace
A Chimney smoke scrubber for use with stoves and fireplaces includes a chimney cap enclosure secured atop the chimney or flue pipe of the combustion unit. The combustion gases from the enclosure are delivered through a duct to a smoke scrubber assembly. The scrubber assembly includes a tank holding a charge of water, with flow space above the water surface for smoke to pass. A stack extends upwardly from the flow space of the tank to release the flue gas to atmosphere.The upper end of the stack includes outlet holes or a screen, and a stack cap having an interior deflector. A nozzle is disposed within the stack and directed to emit controlled spray upwardly to impinge on the deflector cap. The Spray and the deflected water form a curtain of water that cascades downward past the outlet holes or screen, so that the smoke and gases must pass through the water cascade as they are discharged. The smoke and flue gases are contacted by the water, cooling and cleaning them, extinguishing all cinders and removing all fly ash. A submersible pump within the tank feeds water from the tank to the nozzle. A water input line extends into the tank, and is connected to a float valve which maintains a desired water level and flow space in the tank. The submersible pump is connected to electrical power through a switch disposed within the dwelling adjacent to the stove or fireplace that generates the smoke and flue gas.
