主要优点：脱硫产物为干燥的固体，便于处理，工艺能耗低，无废水，无腐蚀，

The main advantage: the desulfurization product is a dry solid, easy handling, low energy consumption process, no water, no corrosion, low investment and operating costs than the wet. Disadvantages: small unit capacity, high calcium to sulfur, waste recycling difficult, easily sprayed wear, easy to scale the system lime

The main advantages: desulfurization products are dry solids, easy to handle, low process energy consumption, no waste water, no corrosion, investment and operation costs lower than wet method. Disadvantages: small single capacity, calcium sulfur is relatively high, waste slag recovery difficulties, spray is more easy to wear, lime system easy to scale
