Unburned carbon in boiler fly- ash, which represents a loss of efficiency and creates a disposal problem for utilities, is an important current concern as combustion zones are modified for NOx control. There is a great need to characterize the oxidation reactivity of coals and chars. The BYU char laboratory has the capabilities necessary to do a complete kinetic and physical properties characterization. Customer provides char. We also provide a complete set of physical properties including N2 and CO2 surface areas and true and particle densities.
Customer provides only coal.
The measurement capabilities and techniques of the Char Laboratory have been developed by William C. Hecker and a long list of excellent students. Calvin H. Bar tholomew has also provided valuable assistance. 639, September 1995.
