Speciation of Copper in Ash from a Fluidized-Bed Boiler

Copper is one of the most important trace elements in municipal solid waste (MSW) combustion. Knowledge of the speciation of copper is fundamental for the understanding of the effects of copper compounds on the combustion chemistry, the evaluation of the environmental effects of copper in ash leachates, and the development of methods to recover copper from the MSW combustion ash.

Boiler Combustion | CleanBoiler.org

Boiler Combustion. Induced flue gas recirculation utilizes the combustion air fan to recirculate the flue gases back into the flame. A portion of the flue gases are routed by duct work or internally to the combustion air fan, where they are premixed with the combustion air and introduced into the flame through the burner.: Robb LutherSteam Traps · Boiler IntroductionHeating Boiler Operator's Manual: Maintenance, Operation https://by: Mohammad A. Malek, Ph.D., P.E. Abstract: Both a valuable on-the-job tool and a licensing exam study guide, the Heating Boiler Operator's Manual offers boiler professionals a clear, straightforward account of cutting-edge methods for the operation, maintenance, and repair of today's heating boilers.

Nickel and Sulfur Speciation of Residual Oil Fly Ashes

used definitive speciation techniques, X-ray diffraction (XRD) and X-ray absorption fine structure (XAFS) spec-troscopy, to identify the Ni species occurring in two ROFAs sampled from a 400-MW utility boiler stack. Direct speciation measurements indicated that 95% of the total Ni in both fly ashes was present as a mixture of NiSO 4 xH 2

Mercury emission and speciation of coal-fired power plants

The total mercury concentrations in the flue gas from boilers were at the range 20 of 1.92–27.15 μg/m3, which were significantly related to the mercury contents in burned coal. 21 The mercury speciation in flue gas right after the boiler is influenced by the contents of 22 halogen, mercury, and ash in the burned coal. The average mercury
