The boiler pressure vessel is typically a horizontal, closed cylindrical tube surrounded by insulating material. The most common Industrial Hot Water Boilers are two or three passes; each pass being a different set of tubes that the hot flue gas travels through before making a turn within the boiler.

Jun 04, 2003 · As the efficiency of a boiler goes up, the temperature of the flue gases go down, and the gases are more likely to condense in the flue. When combustion efficiency exceeds approximately 83%, there is a good possibility that the flue products will condense.

Economiser. The flue gas temperatures at the boiler outlet are normally roughly 60K above the temperature of the product inside the steam boiler. At an operating pressure of 10 bar, which corresponds to a saturated steam temperature of 185°C, the flue gas temperature is therefore roughly 245°C. This corresponds to a flue gas loss of roughly 11%.

flue gas inlet temperature if the superheater lies directly behind the screen tubes, however, if not, boiler bank tubes upstream of the superheater if any would have an effect on the temperature by reducing its value. A temperature downstream of the boiler bank tubes has to be calculated to obtain the flue gas temperature in this case. 3.

A flue gas analysis of a gas-fired boiler indicates that the CO 2 content is 8% with a gas flue temperature of 204°C (400°F). Determine the overall thermal efficiency of the boiler. Solution. By reading the monograph of Fig. 8.12, the combustion occurs with an excess air of 48% and excess O 2 of 7%. The overall boiler thermal efficiency is about 81%.

Flue gas recirculation, or FGR, is the most effective method of reducing NOx emission from industrial boilers with inputs below 100 MMBtu/hr. FGR entails recirculating a portion of relatively cool exhaust gases back into the combustion process in order to lower the flame temperature …
Free ChatThe flue gas temperature is the temperature of the combustion gases as they exit the boiler. If the flue gas temperature is high, then it is often associated with heat being lost. Flue gas economizers can be installed to recover heat, and enhance the overall boiler efficiency.
