Abstract |
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. |
