ANALYSIS OF FLUE GASES - Project Gutenberg

The total amount of excess oxygen in the flue gases is (O - ½CO); hence N - 3.782 (O - ½CO) represents the nitrogen content in the air actually required for combustion and N ÷ (N - 3.782 [O - ½CO]) is the [Pg 158] ratio of the air supplied to that required. This ratio minus one will be the proportion of excess air.

How to calculate heat loss due to dry flue gas?

Formula: L 1 = {m x C p x (T f - T a) / GCV of fuel} x 100. Where, L 1 = % Heat loss due to dry flue gas. m = Mass of dry flue gas in kg/kg of fuel. = Combustion products from fuel: CO 2 +SO 2 + Nitrogen in fuel + Nitrogen in the actual mass of air supplied + O 2 in flue gas.

How does a Flue Gas Analyser calculate efficiency?

26/09/2018 · For large boilers (1MW and above), typical NO x levels are currently likely to be above 70 mg·kWh ¹ although it is difficult to be specific because there are many combinations of boiler and burner, with the actual levels being influenced by combustion chamber, burner head and flame type, and geometry.. Flue gas recirculation. The flame temperature may be reduced and so lessen NO
