Slagging problem in water-cooled wall gasifiers
Thread Content
In water-cooled wall gasification, does the temperature of the cooling water in the coiled tubes affect slag formation in the gasifier? How does it have an impact? Are there any relevant papers and materials on this topic?

Temperature levels do affect the thickness of the slag layer, but the thickness of this layer is not a fixed value. Excessively high cooling water temperature results in poor cooling effects, higher slag flow, which leads to thinning; in more severe cases, it may even cause the slag to collapse, resulting in damage to the furnace chamber. An excessively low cooling water temperature results in a lower temperature of the slag layer, reduced fluidity, and a thicker slag layer. This also diminishes the heat exchange efficiency, affects steam production, and increases energy consumption. The thickness of the slag layer remains at a dynamic equilibrium point.
