Based on their assumption that the coal contained 1.4 wt% nitrogen, typical of U.S. coals, conversion of fuel- nitrogen to nitric oxide in their experiments ranged from 18 to 25%. More recently, Kaskan and Hughes' studied ammonia/ oxygen/nitrogen flames.

Nov 15, 2020 · For boilers equipped with Selective Catalytic Reduction (SCR) systems for nitrogen oxide (NO x) control, additional SO 3 is produced from oxidation of SO 2 within the SCR catalyst. The flue gas concentration of SO 3 in the economizer gas exit duct or at the SCR inlet, in the case of units with an SCR, has been reported to typically be in the range of a few ppm to 40 ppm.

of nitrogen in the fuel.16 In pulverized coal combustion in a utility boiler, fuel NO x may typically contribute up to 80% of the NO x emissions.14 Formation of fuel NO x depends on the nitrogen content in the fuel and the amount of oxygen available to react with the nitrogen during coal devolatilization in the early stages of com-bustion. Accordingly, fuel NO
