摘要：The role coal in power industry is predicted to be increased in
future that is caused by its large stocks and depletion of oil and gas fields.
Due to production growth, deterioration in mining and geological conditions
and broad mechanization of production, the quality characteristics of coals
as ash content, particle-size distribution, humidity and sulfur content
worsen. Therefore, practically all mined coal requires enriching. The smallgrade
and fine concentrates received after enrichment often happen to be
unsuitable because of their fineness for further processing or direct use.
Therefore briquetting is applied for possibility of further processing or
increased utilization efficiency. Compared to the conventional fuel the
briquetted fuel possesses higher calorific capacity and bigger stability during
storage and transportation.
