The combustion of pulverised coal is of great practical importance. Yet the processes involved are so complex that it is not yet possible to mathematically model them adequately. A chemical kinetic model of laminar methane - air combustion has been developed at Leeds, and has been validated for methane - graphite - air flames. However, validation for coal combustion is required.The programme of research will include measurements of species concentration, burning velocities, particle size and temperature in a low pressure laminar pulverised coal flame. The low pressure facilitates good spatial resolution by extending the reaction zone. In previous work difficulties arose in the measurement of methane - graphite - air flames due to the large graphite concentrations. These difficulties will be overcome, in the present proposal, by the use of a coherent anti-Stokes Raman spectroscopy system. Various coal blends will be studied.The mathematical model will require development in light of experimental findings. Interest will centre around the composition of the gases in regions of significant devolatilisation. Other aspects that require attention are the nature of swelling and porosity, and the introduction of NOx kinetics.
