HGI for coal is determined by grinding 50 g of sample in a ball and ring type mill for 60 revolutions, after which the product is sieved through a 200 mesh sieve (75 micron screen) (Speight, 1994). HGI is computed by measuring the undersize of the product. Coals with higher HGI are easy to grind (Speight, 1994).

 · In fluidized bed plants, coal is burned with air in a circulating bed, typically made of crushed coal combined with limestone The advantage of this technology is that it is suited to a wide variety of coals and nocoal fuels such as biomass. An advantage of CFB technology is that it favors low NO x formation and capture of SO 2.
