What is the effect of volatile matter on boiler combustion?

Coal with high volatile matter is easy to catch fire, and the combustion is stable and complete. So, the fineness of pulverized coal can be coarser. The disadvantage is that it is easy to deflagrate. Coal with low volatile matter and high carbon content is not easy to ignite and burn, so the fineness of the pulverized coal is required to be finer.
