Pulverization characteristics of coal affected by magmatic

11.08.2017When category III, IV and V damage is involved, the coal strength is extremely low and the pulverization degree is high, resulting in high levels of outburst risk ( Yu and Cheng, 2012 ). The geological structure involved plays a central role in controlling the development and distribution of tectonic coal.

Energies

In pulverization, biomass has poor grindability owing to its fibrous structure, which increases the power consumption and deteriorates the coal grindability if co-milled [ 3 ]. This can also cause poor burnout of char, which leads to a high unburned carbon (UBC) content in the ash from a large utility boiler adopting pulverized fuel combustion.
