Arisings of coal byproducts are increasing dramatically with economic development. In China the amount of fly ash discharged is more than 100 million tonnes per year, but in recent years about 60 million tonnes per year has been utilized. This situation and some technologies for the utilization of fly ash in China, particularly in Shanghai, will be introduced in this paper. The requirements for environment protection has meant that clean coal byproducts are becoming increasingly common in China. The development of technologies for utilizing the clean coal ash is our new task. This paper explores some utilization methods, not only for FGD gypsum by wet technology, but also the clean coal byproducts rich in sulfur dioxide (SO2), which will be also introduced in the paper.
