 ## ﻿how to calculate the boiler flue gas nitrogen oxynitride ### 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.

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
