The kiln heat provided by coal combustion should preheat the pellets to ensure that the temperature of the chain grate does not fall below 1223 K . On this basis, coal with a lower ignition temperature and a longer burn-up time is required during the rotary kiln process. Therefore, C coal is a kind of high quality coal for a rotary kiln.

The results suggest that the rotary kiln boiler, as designed, is ill-suited with respect to low-grade, hard to burn solid fuels, such as anthracite culm. Indeed, data from combustion of bituminous coal in the PEDCO unit suggest that with respect to coal in general, the rotary kiln boiler appears inferior to the circulating fluid bed boiler.
