0引言浙江省沿海城市分布着众多规模大、货运环境复杂的临海发电厂,为浙江的经济发展提供重要能源。除浙江、福建、黑龙江等3省外,我国其他地区都有非常丰富的天然石膏资源,目前已探明的天然石膏储量大约在570亿t,居世界之首。相比排烟脱硫石膏,天然石膏没有技术上的优势且开发成本较高,应用受到阻碍;而排烟脱硫石膏作为烟煤电厂的副产品,具有来源稳定、产品品质好、价格低廉等优点,排烟脱硫石膏的应
0 Introduction Coastal cities in Zhejiang Province are home to a large number of large-scale coastal power plants with a complex freight environment that provide important energy sources for the economic development of Zhejiang. Except for the three provinces of Zhejiang, Fujian and Heilongjiang, natural gypsum resources are abundant in other parts of China. At present, the proven reserves of natural gypsum are about 57 billion tons, ranking first in the world. Compared with flue gas desulfurization gypsum, natural gypsum has no technical advantages and high development costs, and applications are hindered. As a by-product of bituminous coal power plants, flue gas desulfurization gypsum has the advantages of stable source, good product quality and low price, Gypsum should be
