This type of coal contains up to 12 % moisture (3-4 % fixed moisture) and has a higher heat of combustion as compared to brown coal. It contains up to 32 % volatile matter, which results in a higher flammability. Hard coal is formed from brown coal at depths of about 3 kilometers. Brown coal. Brown coal is a solid pit coal formed from peat.

produce the gas. The char/coke is internally separated and returned to a BFB combustor producing the heat. In 2008 experiments were done with the MILENA operated on a mixture of wood and brown coal. These experiments showed that with increasing amount of brown coal the carbon conversion in the gasification section reduced (Vreugdenhil et al. 2009).
