Preliminary small-scale combustion tests of coal liquids

Nitrogen oxides from burning forest fuels examined by thermogravimetry and evolved gas analysis

“…Fuel nitrogen has been shown to be the major source of NO, emissions from the combustion of oil [ll] and coal-derived liquid fuels [12]. In a recent study by Pershing and Wendt [ 131, pulverized coal containing l-2% nitrogen was burned in air and in mixtures of oxygen and argon.…”
