Abstract
A mathematical model for pulverized fuel flame predictions has been applied to pulverized coal and peat flames. This paper presents the mathematical model used and the evaluation of the model for a pulverized coal flame. The coal flame is generally well predicted. even in the ignition part of the flame. Differences between peat and other pulverized fuels are discussed. The peat contains more volatile matter and has a higher oxygen content, which has to be considered in the modelling of devolatilization. Some measurements of temperature and incident radiation in two pulverized peat flames are compared to the predictions. It is concluded that the ignition phase in the peat flames is not as well predicted as for the case of the coal flames. The devolatilization model used for the predictions is found to work well for the coal flame, but less satisfactorily for the peat flames.
