Influence of silica and alumina (SiO 2 + Al 2 O 3 ) on crystallization characteristics of synthetic coal slags

Crystallization inside the liquid slag of entrained flow gasifiers can increase the viscosity of the slag, affecting flow down the wall and resulting in operational problems. The chemical component of the slag is an intrinsic factor of crystallization characteristics. In the study presented here, Differential Scanning Calorimetry (DSC) and the Single Hot Thermocouple Technique (SHTT) were combined to investigate the influence of (SiO2 + Al2O3)...
