Coal plant
By Greg Bierie, R. Todd Swinderman, and Andrew D. Marti
The requirements placed on belt conveyors have become increasingly complicated with respect to predictable and reliable operation and the reduction of fugitive, especially dust, emissions. The proven techniques of using engineered-flow chutes and air-supported belt conveyors can be found at many coal-fired power plants and this equipment [...]

Babcock & Wilcox Power Generation Group, Inc. (B&W PGG) researchers have successfully captured carbon dioxide (CO2) emissions from a pilot-scale, coal-fired boiler using advanced solvents and a proprietary CO2-capture process developed at the company’s research center in Barberton, Ohio. B&W PGG is an operating unit of The Babcock & Wilcox Company.
B&W PGG has conducted its [...]

Pulverizer throughput is determined by the coal fineness desired for a given coal. However, compromising on coal fineness when your pulverizer isn’t up to snuff can increase NOx and cause many furnace problems. Your least costly option for increasing pulverizer capacity is to pay careful attention to key dimensions and critical tolerances during your next overhaul.
We [...]

Officials at Masonic Village at Elizabethtown, Pennsylvania, U.S.A., weary of the campus’ 90-year-old, inefficient coal-fired steam system, and the high emissions associated with burning coal, knew it was time to move to a next-generation technology for their heating and electric needs — combined heat and power (CHP).
In 2002, eager for a change and after conducting deep [...]

Best Management Practices for Coal Ash Ponds
The unfortunate coal ash spill at the Tennessee Valley Authority’s (TVA’s) Kingston Fossil Plant that occurred on December 22 has heightened national awareness of the problems associated with utilities’ coal ash surface impoundments if they are not properly maintained.
Regulations governing coal combustion waste disposal vary considerably from state to state.
At this time [...]

Virginia Tech University in the US says that it has successfully developed a dewatering technology for ultrafine coal which can reduce moisture content to less than 20%.
Very fine coal with the consistency of talcum powder usually has to be discarded by even the most advanced coal cleaning plants because its moisture content in conventional dewatering systems [...]
