Sulfur release from Ohio coals and sorbent kinetics in pulverized coal flames. Final report
- Ohio State Univ., Columbus, OH (United States). Robinson Lab.
In this report we describe the results of investigations into the structure of combustion and sulfur release profiles from coal burning in One-Dimensional P.C. flames using a furnace of unique design for the measurements. Selected measurements were also-carried out in a special high-intensity furnace also of unique design. The formal project work started in late Fall 1989, with unfunded preliminary work in the months prior to that. The process of limestone injection into the flame to control sulfur oxides emissions is a long-standing concept that has been given particular formulation in the LIMB process, and studies of such systems provide bases for commercial system economics. Problems with LIMB and related systems indicated need for better understanding of, jointly, the sulfur release from the coal and the sorbent behavior by the limestone. The investigations as reported in Vol. 1 of this Report used 14 different coals under a range of different initial and operating conditions, and the resulting measurements have provided a database of major proportions, as tabulated in the attached Volumes 2, 3, 4, 5, 6, and 7 of this report. This database consists of sets of measurements totalling about 45,000 entries for all independent and dependent parameters involved. The independent parameters included: coal type (analysis), firing rate, stoichiometry (fuel/air ratio), and sorbent content of the
