coal handling equipment, but for reasons other than efficiency at low turndown. Specifically, VFDs are used to reduce excess strains on equipment, such as belts and conveyors during startup, and their application for reducing energy demands at turndown is not significantly applicable due to the intermittent operation of the coal handling equipment.
1.2 Anthracite Coal Combustion 1.2.1 General1-5 Coal is a complex combination of organic matter and inorganic ash formed over eons from successive layers of fallen vegetation. Coals are classified by rank according to their progressive alteration in the natural metamorphosis from lignite to anthracite. Coal rank depends on volatile
residual coal. Gob can now be economically burned because of advanced technology. zThe technology offers the cleanest burning, minimally polluting coal-fired power generating stations in the world. zAs a bonus, even the byproduct ash of coal refuse combustion has a beneficial use in reclamation projects.

2 from coal combustion. An excellent review of the results of this research and the prospects for coal can be found in a publication of IEA Coal Research 1999. Fluidized-bed combustion FBC of coal, which is a rela-tively new method for reducing sulfur emissions during elec-tricity generation, is gaining wide usage. In this system, finely
It presents information on cleaner and more efficient coal technologies, their current status and development prospects, with a focus on fuel combustion and power generation. The study also focuses on China because of its significant use of coal and the various efforts made for transferring clean coal equipment and technologies to that country.
Coal utilization - Coal utilization - Coal combustion The most common and important use of coal is in combustion, in which heat is generated to produce steam, which in turn powers the turbines that produce electricity. Combustion for electricity generation by utilities is the end use for 86 percent of the coal mined in the United States. The main chemical reactions that contribute to heat ...
