|Boiler and Electric Utility Stakeholders, Scientists and Researchers Invited to May Discussion on Chemical Fractionation Standard
On Monday, May 5, 4-5 p.m., at the Westin Crown Center in Kansas City, Mo., members of ASTM Committee D05 on Coal and Coke will discuss the possible development of a standard that can improve electric-utility boiler performance and design.
ASTM Subcommittee D05.29 on Major Elements in Ash and Trace Elements of Coal invites researchers and other stakeholders to discuss a Standard Practice for Chemical Fractionation to provide information for combustion, slagging and fouling. Individuals can provide feedback at the meeting or by e-mail.
Slagging and fouling are properties of coal which affect boiler performance, says ASTM member Curtis Palmer, Ph.D., research chemist, U.S. Geological Survey, Herndon, Va. Utilities using different boilers often specify coal with certain properties based on major element compositions, says Palmer, chairman of an ASTM Task Group on Chemical Fractionation. However because elements can have different modes of occurrence, these factors have large uncertainties. If a better specification could be written, much more consistent results could be expected from boiler performance and perhaps better boiler designs would result.
The task group will discuss ISO Procedure 1952, a related Australian procedure, and the benefit of developing a research procedure instead of an industrial procedure.
Contact Curtis Palmer, Ph.D., U.S. Geological Survey, Herndon, Va. (phone: 703/648-6185). For the meeting date and time, contact Scott Orthey, manager, ASTM International (phone: 610/832-9730). //
