The effect of blending of bituminous and sub-bituminous coals on ash fusibility and deposition formation

摘要

Coal is an important energy source whose consumption increases continuously. One of the many ways to use coal is coal blending, which is a very effective technique in power stations. However, coal blending generates unsuspected problems, one of which is ash deposition that causes slagging and fouling. In fact, most blends accelerate and generate heavier ash depositions than their parent coals.
