  • Characterization of slag from combustion of pulverized

    The Mae Moh lignite showed a medium to high slagging tendency Increasing the slagging index led to a decrease in the ash fusibility temperature, due mainly to increasing amounts ofHigh CaO in ash of the lignite is that main issue that can affect severe slag in future operation of the s It boiler is a major challenge faceby d EGAT engineers Slag is waste products from lignite incineration Main products are fly ash and bottom ash Slag is caused by many factors, such as the coal organic properties, coal mineral matter properties, mineral transformation and decomposition,Prediction of Slag Occurrence in a LigniteFired UtilityThe Xinjiang lignite slag viscosity was accurately measured by the MIP method For a coal ash slag, its viscosity is normally dominated by the silicate structure An acidic slag rich in silicate ions is highly viscous whereas a basic slag with small depolymerised silicates is much more fluidic To date, plenty of studies have beenXinjiang lignite ash slagging and flow under the weak
