Prediction of Slag Occurrence in a Lignite-Fired Utility

Abstract Lignite from Mae Moh mine is the largest source of solid fuel for electricity generation in Thailand. It is used in pulverized coal-fired boilers of a 2400 MW thermal power plant. Its high CaO content in ash is a major concern that can affect severeslagging . In this paper, potential of slag occurrence in the power plant was
