Flue Venting - Natural Gas Efficiency

Any furnace with a metal flue pipe and open front that pulls combustion air from the inside, heated space, cannot be more than about 80% combustion efficiency, and is much lower seasonal efficiency due to all the heated air lost up the flue during off-cycles. Condensing Furnace – has a plastic flue pipe; a second heat exchanger removes so much heat from the combustion gases that the …

I use a gas furnace, do I still need to clean my flue

Example #1 - Determination of the Flue Gas Temperature from a Natural Gas Furnace In this specific example the combustion device is an older lower efficiency Natural Gas Home Furnace. The fuel is considered to be Standard Natural Gas (1040 Btu/std. ft3 ), the fuel consumption is 100,000 Btu/hr (HHV Basis), and the heat delivered to the home is 80,000 Btu/hour.

from natural gas-fired boilers are flue gas recirculation (FGR) and low NOx burners. In an FGR system, a portion of the flue gas is recycled from the stack to the burner windbox. Upon entering the windbox, the recirculated gas is mixed with combustion air prior to being fed to the burner. The recycled flue gas
