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

Flue Gas Analysis Table Introduction. See Flue Gas Analysis. Operation. Using a Flue Gas Analyzer or any meter designed to measure oxygen or carbon-monoxide, and taking the flue gas temperature and the temperature of the combustion air, the following Table can be used to determine combustion efficiency when operating on natural gas.

and on the heating surface of the Exhaust Gas Boilers. The reasonable optimal steam production of Exhaust Gas Boilerswhere no economizers are incorporated are consequently reached at a steam pressure of 3-4 bar (saturated temperature 143-151°C). In practice it is found that the pinch temperature shall be kept at minimum 25°C as a lower

Is PVC an acceptable vent material for flue gases?

In condensing boilers, the flue gas is cooled down to a temperature at which water vapour condenses. All or part of the energy that water vapour contains is recovered. For condensing boilers, the condensation takes place at temperatures below 60 °C (dew point temperature), depending on how much additional air (excess air) the exhaust gas contains.

Type "B", due to its temperature rating, can only be used with atmospheric gas water heaters. All venting installations must conform with local codes. In the absence of local codes, refer to "National Fuel Gas Code" NFPA 54 and "Standard for the Installation of Oil-burning Equipment" NFPA 31 (Tables 21-33 are based on NFPA 54).
