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).
The changes of oxygencontaining functional groups and gas composition during the grinding of coal samples under different atmosphere conditions were further tested. The main purpose of the experiment is to study the mechanochemical effect of coal during the grinding process and its effect on coal spontaneous combustion. 2. Experiments
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (, via a hand crank), working animal (, horse mill), wind or water ().

We have had our Keystoker 90,000 btu stoker stove for about 10 years. It is one of the best investments that I have ever made. We have a ranch house with a full finished basement and this stove keeps the main floor and basement at 72 degrees all winter. We usually burn about 2 tons of rice coal .
Coalfired boilers are mainly operated at either subcritical or supercritical conditions. From a thermophysics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of MPa and the corresponding saturation temperature of 374 °C (Shen and Cheng, 2004).

Abstract Grinding of a high volatile bituminous coal was performed in three comminution devices: Raymond Mill (RM), Rolls Crusher (RC) and Ball Mill (BM). The pulverised samples were sieved to obtain four particle size fractions, and temperatureprogrammed combustion (TPC) was used for the evaluation of their combustion behaviour. In addition, three coals of different hardness and rank were ...
