Coal is an organic rock (as opposed to most other rocks in the earths 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).
one coal bed. The detailed study of coal beds is important for both utilization and geologic studies. In addition to being of value in mine planning and utilization, coal research gives clues to the geologic processes that formed the coal bed. 1.2 Types of Samples Coal is the major rock type processed in the laboratory.

To summarize the coal mill controls, they may be divided basically into two major categories. 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.
