ABRASION INDEX PROFICIENCY TESTING REPORT .
The coal used in this proficiency testing round was bituminous coal. 2. PREPARATION OF SAMPLE Approximately 650kg's of sample with an approximate topsize of 50mm was sourced. This was crushed to mm using a jaw crusher. The screen was placed on a 600um screen and the mm material screened in batches of about 5kgs.
Design Considerations for Pulverized Coal Fired Boilers ...
In order to quantify fly ash erosion, Raask developed an index analogous to the abrasion index for coal. The fly ash erosion index recognizes that wear on boiler pressure parts is primarily due to the fly ash fraction greater that 45 µm. The relative coarseness of flyash can be graded into three categories:

The main quality requirements are (i) high Fe content with less gangue and deleterious elements like phosphorous and sulphur, (ii) good handling properties (tumbler index and abrasion index), (iii) calibrated to size with less fines, (iv) high reducibility, (v) low decrepitation during reduction, and (vi) good compatibility with the reductant coal used.
Coal: Anthracite, Bituminous, Coke, Pictures, Formation, Uses
Coal is also used as a power source for factories. There it is used to heat steam, and the steam is used to drive mechanical devices. A few decades ago most coal was used for space heating. Some coal is still used that way, but other fuels and coalproduced electricity are now used instead. Coke production remains an important use of coal.

These 25 largest operators of coal plants (all privatelyowned corporations, with the exception of the TVA, which is a publiclyowned corporation) own 264 out of the 614 coalfired power plants in the ; these 264 plants produced a total of 1,425,653 GWh of electricity in 2005 (% of total coalfired power production).
abrasive index of coal
Abrasion index is an index that shows the abrasive properties (abrasion) of coal on the part of the equipment used to grind the coal before being used as fuel in certain combustion systems The higher the index the abrasive coal the higher the maintenance costs of the coal grinding equipment...
Coal assay Wikipedia
Abrasion testing. Abrasion is the property of the coal which describes its propensity and ability to wear away machinery and undergo autonomous grinding. While carbonaceous matter in coal is relatively soft, quartz and other mineral constituents in coal are quite abrasive. This is tested in a calibrated mill, containing four blades of known mass.
Corrosion Protection Pays Off for CoalFired Power Plants ...
Conveyor and chute steel abrasion caused by contact with coal is also a significant issue in coal plants. Using hotdip galvanized steel can eliminate this issue because it is difficult for the coal to damage the coating as the zinciron alloy layers are harder than the substrate steel.
