ABSTRACT:
There are disclosed means and method for improving the efficiency of combustion in an automatic gas-fired furnace through retardation, without restriction, of the exhaust emission of the products of combustion, which are caused to dwell longer in the combustion chamber to elevate the temperature, not only through the impoundment of what would otherwise be waste heat, but by the conversion of CO gas and excess air to CO.sub.2 gas, thus, reducing the two former, increasing the latter, along with temperature. This reduces the condensate in the exhaust chimney. An enlarged chamber in the exhaust gas conduit is incorporated within and beneath the line of exhaust flow from furnace to chimney. A baffle plate, approximately equal in area to the cross-sectional area of the conduit, is immovably secured in the top of the chamber normal to the line of exhaust flow. The chamber is completely closed except for the exhaust flow entry and exit ports. The chamber affords clearance beneath or around the baffle for the unimpeded passage of the exhaust gases equal in area, or greater than, that of the exhaust gas conduit.
