Coal is an organic rock (as opposed to most other rocks in the earth's crust, such as clays and sandstone, which are inorganic); it contains mostly carbon (C), but it also has hydrogen (H), oxygen (O), sulfur (S) and nitrogen (N), as well as some inorganic constituents (minerals) and water (H2O).Reducing the cost of fuel is a common strategy employed within the industry; in turn, this has led to an increase in the substitution of coal with petcoke. Petcoke and its impact on the coal mill dust collector One area that has been impacted by the use of petcoke is the coal mill dust collector.
