Coal and Charcoal Testing

Introduction to Coal and Charcoal Testing

Coal and charcoal testing is an important activity in assessing carbonaceous materials before use in applications such as energy generation and processing. Coal and charcoal testing is focused on the identification of characteristic features such as calorific value, ash content, moisture content, and volatile matter as critical to the actual and forecasted performance and efficiency. Through coal and charcoal testing, various industries, including transportation, can meet the set standards, conserve fuel, and make proper decisions when it comes to procurement and usage of a given product.

Instrumentation of Coal and Charcoal Testing

The apparatus for analyzing the coals and charcoal involves several apparatus and instruments used to determine the physical and chemical characteristics of the two substances. A calorimeter is used to measure the calorific value, which determines the energy content of the fuel. Moisture analyzer, which evaluates the moisture content, and ash fusion tester, which provides ash features. Analyzers of proximate and ultimate include volatile matter, fixed carbon, and elements. In combination, all these instruments are a source of solid support in determining quality and the efficient application of coal and charcoals in different processes.
