X-ray Diffraction Examination of Coal Combustion Products Related to Boiler Tube Fouling and Slagging

Abstract

The Morgantown Energy Research Center of ERDA is studying fouling and slagging of pulverized coal fired boiler tubes resulting from mineral matter contained in the coal. The research is dependent on the development and application of reliable analytical techniques which can be applied to the coal and ash products to determine the mineral interactions responsible for fouling and slagging. X-ray powder diffraction is one of the techniques used to characterize the feed coals and their combustion products. A summary of the methods and techniques applied at MERC is the subject of this paper.
