Formation and control of NO emissions from coal-fired spreader-stoker boilers

OSTI ID:6112392
The paper describes results of a study on the formation and control of nitrogen oxide (NO) in coal-fired spreader-stoker systems. (Stoker-coal-fired furnaces are significant in terms of coal consumption and environmental impact: however, they have received little research attention.) Three scales of experimental equipment were used to define the evolution and oxidation of fuel nitrogen in the fuel-suspension phase, the conversion of fuel nitrogen during fixed-bed combustion, and the coupling between the two combustion phases. Results indicate that NO emissions from spreader-stoker coal-fired furnaces are the result of relatively high conversions of fuel nitrogen evolved from particles of < 0.1 in. diameter in the suspension phase and low conversion of fuel nitrogen during fixed-bed combustion.
