Desulfurization Kiln

Wet desulfurization flue gas reheating system in cement

With the restrictions on mining and the reduction of high-quality limestone stock, many cement plants have to use low-grade limestone, resulting in excessive SO2 in the flue gas of kiln tail, and some cement plants with substandard discharge began to adopt the wet method (kiln ash-gypsum method) for desulfurization.
