Cited by 2Pulverized coal injection may affect the final steel products. Pulverized coal may reduce gas permeability of the metal and unburnt coal particles may accumulate in the furnace decreasing efficiency. Thus it may not be possible to substitute pulverized coal for coke in the production of high quality steel.
Spontaneous combustion often occurs in piles of hydrocarbonsoaked (oily) rags and can constitute a serious fire hazard. Fires started by spontaneous combustion are caused by the following mechanisms (1) spontaneous heating (2) pyrophoricity and (3) hypergolic reactions. Spontaneous heating is the slow oxidation of an element or compound
