The symbol representing the basis of coal quality analysis test
Coal quality analysis tests are used to determine the amount of coal, ash, volatile matter, fixed carbon, and sulphur in each sample of coal. The tests are performed using a range of laboratory analysis equipment, including Sulfur-Abel Analyzers, Bomb Calorimeters, Fixed Carbon Analyzers, and Ash Fusion Analyzers. These tests are crucial for determining the best uses for a given coal sample and for ensuring the safety of coal production operations.
The symbol for the basis of coal quality analysis tests is a combination of letters and numbers within square brackets. These symbols are meant to provide a way of identifying different coal samples and to help identify the tests that were used. Each symbol starts with the letter “A” and is followed by a series of numbers and an optional letter code at the end. The letters at the end of the symbols are used to indicate the type of sample that is being tested or the source of the coal.
For example, the symbol [A 25-5E] is used to indicate that a sample of coal was obtained from the 25thhole, with the fifth analyzer test; and the “E” in the final position indicates that the coal was sampled from an eastern source. On the other hand, the symbol [A 4-5F] would indicate that the sample was obtained from the fourth hole and was tested with the fifth analyzer test and the “F” indicates that the sample was from a western source.
In addition to the symbols used to indicate the results of the coal quality analysis tests, the symbols can also be used to indicate the types of tests that were performed. For example, symbols may be used to indicate that an ash fusion test has been performed, or that a calorific value (CV) test has been performed.
By providing a standardized way for identifying and reporting coal samples, these symbols help to ensure that coal analysis and quality control operations are accurately reported and that all necessary testing was performed. This allows coal producers to be sure that their coal has been thoroughly analyzed and meets the necessary safety requirements. The symbols also help to ensure that coal production operations are as safe and efficient as possible.
