The research examined two case studies—one using woody biomass in central Alabama and the other using switchgrass in the Ohio River Valley—for blending a relatively high volume of torrefied biomass with ground coal in pulverized coal power plants.
This study highlighted on coal production and reserves in Nigeria, chemical characteristics of air dried coal and utilization potential of the Nigerian coal in the domestic and industrial sectors. It discussed coal briquetting technology and processes involved in producing smokeless briquette fuel coal drying, screening, crushing and carbonization to remove obnoxious volatile matters.
Pulverized Coal Coal is an abundant and lowcost fuel for boilers. It can be burned in a number of ways depending on the characteristics of the coal and the particular boiler application. Various firing methods for the burning of coal are used: cyclone furnaces, stokers, pulverized coal, and fluidized bed.

In an oxycombustion pulverizedcoalfired power plant (PC), a high CO 2 content flue gas could be obtained, and this allows CO 2 sequestration in an efficient and energysaving way. To better understand the thermodynamic characteristics of the oxycombustion process, a detailed exergy analysis of a 600 MW e oxycombustion PC was carried out.
Wetbottom units may be fired by crushed coal, such as is fed to cyclone furnaces, or by pulverized coal. The pulverized coalfired wetbottom unit traps 50% or less of the ash as molten slag on the furnace walls; this slag runs down to the furnace floor and taps down into the slag tanks for removal.
LowRank Coals for Power Generation, Fuel and Chemical Production provides a thorough introduction to lignite (brown coal) and subbituminous coals and explores how they can be used efficiently and economically in place of hard coal.
