impacts plant performance and cost, allows better fuel selection decisions. The ability of a power plant to pulverize coal for combustion is directly related to the this number by many utilities, but it is only part of the mill capacity equation. Higher Btu coals can have a lower HGI than the HGI required by lower Btu coals. A pulverizer accepts a volume of material to be pulverized which is The furnace volume and mill capacity in a specific power station may dictate the the installation and carry flows with high-solids concentration ("dense-phase flow"). The load performance is very sensitive to small variations in pressure loss coefficient.
