What temperatures are normal in this area of my furnace

1.4 Natural Gas Combustion - US EPA

The temperature of the exhaust will be high because of the heat that is transferred to the exhaust during combustion. Because of its high temperature, exhaust usually occurs as a gas, but there can be liquid or solid exhaust products as well. Water (H2O) is always present in natural gas and oil combustion in residential furnaces.

The "net stack temperature" is the difference between the flue gas inside the chimney and the room temperature outside the burner. Net stack temperatures above 700oF (370oC) are in general to high. Typical values are between 330 - 500oF (160 - 260oC). High stack temperatures may be caused by

What Are the Causes of Excessive Fuel Consumption in Gas

19/11/2014 · With the current settings the gas burner cycles like this. -limit temperature 200F. -at that temperature the burner shuts off and the furnace is cooling off to around 150F in about 35 seconds. From there the burner starts again and it the temperature goes up in about 1min. The temperatures in the circled area are the highest in the area but stable.

01/11/2019 · For Natural Gas (Methane), the blue flame temperature is about 1,960°C. If you ever took a high school chemistry class and had a chance to use a Bunsen burner, you know how adjusting the air (oxygen) supply affects the colour and temperature of the flame.

Understanding Combustion Efficiency and Combustion Equations

04/01/2015 · The house is a two story colonial with a full basement. Lots of big windows and a total of 2500 sq ft. A 100K BTU furnace could be a little big for the house but not outrageously so. The furnace has not tripped the high temperature limit since changing to the MERV 2 filter. I don't want to use this filter too long for obvious reasons.

Too little draft can reduce the combustion air delivery of the burner and can cause smoke. Excessively high draft increases the air delivery of the burner fan and can increase air leakage into the heating plant, reducing CO2 and raising stack temperature, resulting in reduced operating efficiency.
