Bituminous coal, renowned for its hardness and lower sulfur content, is distinguished by the presence of a tar-like substance known as bitumen. This specific coal variant proves to be of immense value in domestic applications, particularly after undergoing the transformation into coke fuel. In contrast, Sub-bituminous coal, strategically positioned between lignite and bituminous coal, emerges as a primary fuel source for steam-electric power generation. Its versatile applications extend beyond, encompassing the pivotal role of powering stations and fueling cement works in Pakistan, thus solidifying its significance in the nation’s energy landscape.
