Abstract:
1. An apparatus for promoting a cleaner burn of fuel within a combustion chamber of a fireplace, the apparatus comprising; a hollow tubular conduit defining a first end portion in fluid communication with an air source; a second end portion with a plurality of air apertures and a middle portion in fluid communication with the first and second end portions wherein the middle portion supports the second end portion, the second end portion disposable in a secondary combustion zone of the combustion chamber of the fireplace so that the plurality of air apertures are disposed in the secondary combustion zone, the second end portion of the hollow tubular conduit defines an upper frame having first, second, third and fourth hollow tubes in fluid communication with each other, the first and third tubes being generally parallel with each other, the second and fourth hollow tubes being generally parallel to each other such that the upper frame substantially fills the secondary combustion zone of the combustion chamber of the fireplace, the middle portion having fifth and sixth tubes in fluid communication with the upper frame; first and second horizontal expansion sleeves telescoping with the first and third tubes for adjusting a width of the apparatus to fit a range of combustion chamber sizes; third and fourth vertical expansion sleeves telescoping with the fifth and sixth tubes for adjusting a height of the apparatus to fit a range of combustion chamber sizes; and a means for flowing air through the hollow tubular conduit from the first end portion to the second end portion through the air apertures for introducing oxygen to the secondary combustion zone of the combustion chamber which has oxygen starved air to encourage complete combustion and reduction of harmful emissions.
