Lignite also known as firewood coal is a mineral coal with the lowest degree of coalification. It is a brown black, lusterless low-grade coal between peat and bituminous coal. Strong chemical reactivity, easy weathering in the air, not easy to store and transport. Because it is rich in volatile matter, which is up to more than 40%, it is easy to burn and smoke.
