Bituminous coal is a dense rock black but sometimes dark brown. It is a relatively soft coal that breaks and burns readily and quickly. It used as fuel in power stations and for heat and power applications in manufacturing for blacksmithing and to make coke. Steam coal was once widely used as a fuel for steam locomotives.
