1.4 Natural Gas Combustion - US EPA

In the desulphurisation process about 10% of NO is oxidised to NO 2 before the flue gas reaches the scrubber. The scrubber then removes about 20% of the total NO x in equal parts of NO and NO 2. (ii) Absorption by Lime: Aqueous suspension of calcium hydroxide can be used as the scrubber to reduce NO x levels to 200 ppm. The calcium nitrite in the solution can further be converted to more valuable …

generate hydrocarbon radicals that reduce to ni-trogen the nitrogen oxides that are formed. The combustion process is then completed by add-ing the balance of the combustion air through overfire air ports in a final burnout zone at the top of the furnace. Staged combustion (off-stoichiometric combustion) burns the fuel in two or more steps. Staged com-
