Bonding Index of Coal Quality Indicators
Coal quality indicators are measurements that provide the specifications of various coal grades, including the determination of their calorific values. The calorific value of coal is determined to be a reliable way to assess the rank of the coal, which can accurately indicate the combustible power of the coal. One of the coal quality indicator tests commonly used to measure the combustible properties of coal is the Bonding Index.
The Bonding Index is an important coal quality indicator for determining the available combustible energy of coal over a certain range. It is used to assess the maximum potential output of a given coal grade and its combustibility. Generally speaking, tests are used to evaluate the Bonding Index of coal by burning a weighted sample of coal and measuring the amount of heat generated. The Bonding Index of coal is then determined by comparing the measured heat value to the heat value derived from other coal samples of similar grade.
The Bonding Index of coal is related to its caking properties. Coking properties are the mechanical properties of coal that affect the strength of the coal briquettes and pellets that are used in steel production. The caking properties of a given coal grade are determined by measuring the shrinkage, plasticity and strength of the coal briquettes and pellets. The Bonding Index is related to the caking properties as it serves as an indirect measure of the degree of caking of the coal. The Bonding Index of coal can therefore be used to determine the grade and combustibility of a given coal.
The Bonding Index of coal is often used to verify the quality of coal when purchased or traded. Buyers of coal may use the Bonding Index of coal to assess the availability of combustible energy of the coal. Sellers of coal may use it to evaluate the quality of coal and its suitable grade for the application. Producers of coal may use this measurement to determine the grade of coal they are producing and the availability of combustible energy of the coal.
In conclusion, the Bonding Index of coal is a reliable coal quality indicator that provides a direct measure of the combustible energy of coal grades. It is used to assess the grade of coal and its caking properties, and is often used in the purchase and sale of coal. The Bonding Index of coal can also be used to assess the combustibility of a given grade and its maximum energy output.
