Boiler Flue Gas Temperature Calculation

What temperature should a condensing boiler be set at

Jan 09, 2013 · FGR is the process by which exhaust gas is introduced into the combustion-air stream prior to a burner. Flue gas also is relatively cool (300°F to 550°F, depending on the design of the boiler and whether there is a feedwater economizer) with respect to flame temperature, and flue gas has little oxygen from the combustion process.

Gas Boiler Efficiency Calculation

The current calculation method of the acid dew-point temperature of the flue gas is multifarious, and many formulas even exist obvious errors. In this paper, the representative method is used to calculate the acid dew-point temperature of the flue gas, and the Influence factors of the acid dew-point temperature are analyzed. Finally, the optimum calculation

Prediction of flue gas acid dew point temperature

Flue Gas Analysis as a Boiler Diagnostic Tool Overview, and Traditional Application Combustion flue gas analysis has been used by Power Plant Operators for decades as a method of optimizing fuel/air ratio. By measuring the amount of excess oxygen and/or CO in the flue gases resulting from combustion, plant operators can operate at the best

Mass And Energy Balances Over Oil Fired Boiler Engineering

A periodic boiler flue-gas analysis is the best indicator that an adequate supply of combustion air exists. This, and any necessary burner adjustments, should be performed by a trained technician with the proper equipment to measure the amount of excess oxygen and/or carbon dioxide and ppm of carbon monoxide.

A condensing boiler is one of the most efficient types of boiler. This is because it is able to recover virtually all the heat from the flue gases and use this to heat your home. For the boiler to work at its most efficient, the heat exchanger needs to be equal to or below the dew point temperature.
