flue gas temperature and heat in the flue gas flow (btu

Flue Gas Temperature and Heat in the Flue Gas Flow (Btu

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.

Is PVC an acceptable vent material for flue gases?

Mar 15, 2014· This control would shut off the burner if the flue gas temperature exceeds the temperature rating of the flue pipe. A standard will be needed for plastic flue pipes that should include a temperature gauge and a high limit probe. Then PVC, CPVC and polypropylene flue gas piping can be safely used on high efficiency boilers and water heaters

measurements indicate an excess air level of 44.9% with a flue gas minus combustion air temperature of 400°F. From the table, the boiler combustion efficiency is 78.2% (E1). Tuning the boiler reduces the excess air to 9.5% with a flue gas minus combustion air temperature of 300°F. The boiler combustion efficiency increases to 83.1% (E2).

flue-gas stack - wikipedia

Flue-gas stack - Wikipedia

A flue-gas stack, also known as a smoke stack, chimney stack or simply as a stack, is a type of chimney, a vertical pipe, channel or similar structure through which combustion product gases called flue gases are exhausted to the outside air. Flue gases are produced when coal, oil, natural gas, wood or any other fuel is combusted in an industrial furnace, a power plant's steam-generating boiler

Therefore, it would be highly desirable if the flue gas mixtures can be used for CO 2 conversion but without pre-separation of CO 2. CO 2 conversion and utilization should be an integral part of CO 2 management, although the amount of CO 2 that can be used for making industrial chemicals is small compared to the quantity of flue gas.
