（1） 脱硫石膏品质
(1) Quality of the desulfurization gypsum
石灰石——石膏湿法脱硫工艺的副产品以二水石膏为主。来自吸收塔的石膏浆用泵打入脱水系统，经旋流分离器，再经脱水机脱水。脱水后的石膏含水率约10%，脱硫石膏的成份（干基）为：
The by-product of Energy Center FGD Process is dehydrated gypsum in main, which comes from gypsum thick liquid of absorbing tower and pumps into the dehydrating system, through the swirl separator, and then dehydrate by the hydroextractor. The moisture content of gypsum after dehydrating is about 10%. The compositions (dry basis) of the desulfurization gypsum are:
石膏CaSO4·2H2O： 90.04％
Gypsum CaSO4·2H2O： 90.04％
（折算为SO3： 41.90％）
(Convert into SO3: 41.90% )
飞 灰： 1.76％
Flying ash: 1.76%
杂 质： 5.18％

（2） 脱硫石膏应用
(2) Application of the desulfurization gypsum
石灰石──石膏湿法脱硫副产品为脱硫石膏，利用途径很广泛，在不少领域如水泥、建材行业、建筑以及农业等广泛使用。
The by-product of Energy Center FGD Process is desulfurization gypsum, which used very extensive and used in many fields as cement, building materials, building and agriculture, etc.
在水泥行业，石膏可以作为水泥的掺和料，可起到缓凝作用。目前，水泥中石膏掺和料大多来自天然石膏矿，开采天然石膏矿耗用了国家大量资源。如果采用脱硫石膏替代天然石膏，只要控制脱硫石膏中有害杂质含量、降低脱硫石膏表面水分、或控制石膏造粒等，脱硫石膏就可以替代天然石膏广泛应用于水泥行业。
In the cement trade, the gypsum can play slow coagulation function and used as admixing material of cement. At present, the gypsum admixing materials mostly come from the natural gypsum ore. The exploitation of the natural gypsum ore consumed the ample resources of our country. If the desulfurization gypsum substitutes the natural gypsum, only controlling the harmful impurity content of desulfurization gypsum may reduce the surface moisture of desulfurization gypsum, or controll the gypsum granulation, etc. The desulfurization gypsum can substitute the natural gypsum to apply to the cement trade extensively.
中国硅酸盐学会曾对珞璜电厂的脱硫石膏进行全面性能验证试验，试验结果证明脱硫石膏用作水泥缓凝剂完全可行，脱硫石膏的各项性能指标均可以达到有关标准的要求，有些指标甚至还优于天然石膏，所以，脱硫石膏完全可以替代天然石膏。另外这种工艺技术简单、易于实现。因此在水泥行业，脱硫石膏将会广泛地得到使用。
Chinese silicate society once carried on overall performance and verification test to the desulfurization gypsum of the Luohuang power plant. The result of the test proves that it is totally feasible that the desulfurization gypsum is used as the cement retarder. Each performance index of the desulfurization gypsum can reach the standard requirements. Some indexes are even superior to the natural gypsum; therefore, the desulfurization gypsum can totally substitute the natural gypsum. In addition, this technology is quite simple and easy to realize. So in the cement trade, the desulfurization gypsum will be widely used.
建筑材料，尤其在新型建筑材料中，石膏板及石膏制品占有特殊地位。国内许多石膏板厂就用脱硫石膏作原料。
In construction material, gypsum board and gypsum products occupy the special position especially in the new-type construction material. A lot of domestic gypsum board factories use the desulfurization gypsum as raw materials.
在建筑行业，脱硫石膏也有巨大综合利用的市场。另外，在生产化肥硫酸钾方面，脱硫石膏也会得到广泛使用。
In the building trade, the desulfurization gypsum has markets of enormous and comprehensive application. In addition, in chemical fertilizer production of sulfuric acid potassium, the desulfurization gypsum will be extensively used as well.
脱硫石膏首先立足于综合利用，以保护环境，节约土地，避免资源浪费，并可产生一定的经济效益。本工程采用干灰场，无法采用石膏水力抛弃处理方案，本工程脱硫石膏全部脱水后，运往综合利用用户。脱硫石膏无法综合利用时，石膏脱水后由输送皮带运至电厂干灰场碾压贮存。本工程6台1190t/h锅炉，锅炉采用4运行2台热备用，考虑实际4台锅炉运行脱硫石膏排放量见表7.1-2。
The application of desulfurization gypsum shall base on comprehensive utilization at first, so as to protect the environment, economize the land resource, avoid resources wasting, and produce certain economic benefits. This project adopts the dry ash yard, and unable to adopt gypsum water conservancy throwing disposal scheme. After the dehydrating process of all desulfurization gypsum of this project, it shall be transported to synthetic utilized users. When the desulfurization gypsum is unable to apply synthetic utilization, gypsum after dehydrating shall deliver to power plant gray field for storage after rolling through the transporting belt. The boilers of this project have 4 boilers in operation and 2 boilers stand-by in case of emergency. The actual lime stone consumption of desulfurization process of 4 boilers in operation sees forms 7.1-2.
