Abstract:

The ignition and combustion rates of three types of densified refuse-derived fuel DRDF and low-volatile Illinois bituminous coal were investigated at temperatures ranging from 600 C to 1000 C and residence times ranging up to 120 sec. It was found that DRDF ignition time is up to 12 times less than that of coal, that the temperature required for coal ignition at a given residence time is greater than that needed for DRDF ignition, and that the DRDFcoal time to ignition ratio is expressible as a linear function of furnace temperature. It was also found that DRDF produced from mixed municipal-residential solid waste has a slower combustion rate than that produced from homogeneous heavy paper stock, and that the combustion rates of all types of DRDF are significantly greater than that of the coal tested at a 99.9 percent level of confidence.
