How hot does a gas furnace flue get? - TreeHozz.com

Feb 03, 2015 · Posted By Writer on Feb 3, 2015 | . While most homeowners are aware of the need to clean and inspect their flue if they use a wood burning fireplace or stove, many are not aware of the importance of cleaning and inspecting their flue when gas furnaces and other gas heating appliances are involved.

Carbon Monoxide Detection And The Effect On The Human Body

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

The flue gas temperature can be determine in this case by an iterative process of inputting the flue gas mass flows and an assumed flue gas temperature to see if the Total Flue Gas Btu/hr is equal to 21,194.31 Btu/hour, if not you try another assumed temperature.

1.4 Natural Gas Combustion - US EPA

The current ANSI Z21.47 standard (1998) requires that an air-free flue gas sample of CO not exceed a maximum of 400 ppm (0.04 percent) when a furnace vent is either partially or completely blocked. • During disconnected vent tests: „The average steady-state concentration of CO in the chamber increased as the firing rate increased.

Dec 30, 2017 · A measurement of CO in the undiluted flue gas of an appliance is a good indicator of the quality of combustion. Most modern gas burning appliances will have a CO level less than 50ppm. Some high efficiency boilers will have CO levels up to 175 ppm in the flue. Older natural draft appliances may have CO levels as high as 200 ppm and be still be normal.

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

A three-step method for detecting unacceptable leakage of flue gases through furnace heat exchangers was developed and field tested. The first step of the method is thorough visual examination of the heat exchanger with a strong light and a mirror. Next a check of the burner flames is made with and without the circulating air blower operating.

Apr 24, 2020 · If your home had a 'standard' 80% efficient furnace, the flue gas temperature, the temperature of the air and flue gases exiting the home through the flue pipe, could be as hot as 450-500 degrees; obviously that's a waste of energy, but it's only 20% of the energy contained in the natural gas that is burned in the
