Abstract

Spontaneous ignition and combustion of coal are the major problems for its mining, transportation and usage. The temperature of ignition or combustion of the coal mainly depends upon its rank. Generally, coals having lower ranks are more prone to the spontaneous ignition or combustion than the coal having higher ranks. But many times, as an exception, as the rank increases, the coal becomes more susceptible to spontaneous ignition. As we reduce the particle size, the susceptibility to ignite more efficiently increases. But reducing the size of the coal particle may also increase the volatility. In pulverized combustion, the coal is ground in fine particles and then heated directly. To check the variables which affect the susceptibility of the ignition of the coal, practical experimentation can be carried with some proper combustion setup.
