A piece of good, high-quality coal is a valuable resource with many practical uses. One of the most critical steps in working with coal is ensuring the effective separation of poor from good quality coal. This typically requires a series of accurate carbon, hydrogen and nitrogen determinations.
The CHN828 from LECO is a carbon/hydrogen/nitrogen determinator that employs a vertical quartz furnace and a pure oxygen environment to offer robust sample characterization.

When working with coal, it is possible to use these levels to calculate emission potentials, material/energy balances and reactivity potential – factors that each provide insight into the quality of the coal under investigation.

LECO acquired approximately 0.1 g samples of three different types of coal and analyzed these in tin foil cups using the CHN828. The results of these analyses enabled LECO - and coal producers - to effectively separate poor and good quality coal, ensuring that only the very best coal is used for fuel purposes.
