Bituminous coal specific gravity

WebJan 1, 2016 · Pore characteristics generally change with rank of coal. For low-rank bituminous coals, vitrinite is more microporous and less macroporous than their equivalent inertinite. With rank increase, mesoporosity of vitrinite reduces considerably in comparison to that of inertinite (Crosdale et al. 1998 ). WebJan 5, 2024 · By ASTM standards, sub-bituminous coals have calorific (heating) values of 8,300 to 11,500 Btu/lb (ASTM, 2014). In practice, however, there is considerable overlap between what is called a higher rank sub-bituminous coal (subbituminous A) and a lower rank bituminous (high volatile C) coal.

WebThe Specific Gravity - SG - is a dimensionless unit defined as the ratio of density of the material to the density of water at a specified temperature. It is common to use the density of water at 4 o C (39 o F) as reference - at this point the density of water is at the highest.. Specific gravities - SG - for common solids and metals can be found in the table below: WebGravity Index. Here API denotes the American Petroleum Institute. The API Gravity Index of a given fluid is determined by the following formula: In the equation above, G s denotes the specific gravity of the fluid at atmospheric pressure (14.7 psi) and T=60ºF. 131.5 (15.1) G 141.5 Gravity Index s API = −

This information can be used to tell whether coal will float (or sink) if dropped in water (Buoyancy). Formula SG = ρcoal / ρwater Note: Both densities need to be in the same unit as they will cancel each other and produce SG.

Web(14) The specific gravity of coarse coal refuse normally ranges from 2.0 to 2.8 for bituminous coal refuse and from 1.8 to 2.5 for anthracite coal refuse. The specific gravity is directly proportional to the plasticity index of the refuse. As the plasticity index increases, the specific gravity also increases.
