Pulverised Fuel - an overview ScienceDirect Topics

Pulverized fuel (pf) combustion in a boiler for power generation is by far the most common approach for the utilization of low rank coals. The properties of low rank coals (in particular, moisture and alkali content) mean that such an approach is often very inefficient, leading to very high CO 2 emissions. Low rank coals, however, are inexpensive, and in some regions represent a significant energy resource.
