（1） 脫硫石膏品質

(1) Quality of the desulfurization gypsum

 石灰石——石膏濕法脫硫工藝的副產品以二水石膏為主。來自吸收塔的石膏漿用泵打入脫水系統，經旋流分離器，再經脫水機脫水。脫水后的石膏含水率約10%，脫硫石膏的成份（干基）為：

 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％

（折算為SO₃：     41.90％）

(Convert into SO3: 41.90% )

 飛  灰：          1.76％

Flying ash: 1.76%

 雜  質：          5.18％

（2） 脫硫石膏應用

(2) Application of the desulfurization gypsum

 石灰石──石膏濕法脫硫副產品為脫硫石膏，利用途徑很廣泛，在不少領域如水泥、建材行業、建筑以及農業等廣泛使用。

 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.

 在水泥行業，石膏可以作為水泥的摻和料，可起到緩凝作用。目前，水泥中石膏摻和料大多來自天然石膏礦，開采天然石膏礦耗用了國家大量資源。如果采用脫硫石膏替代天然石膏，只要控制脫硫石膏中有害雜質含量、降低脫硫石膏表面水分、或控制石膏造粒等，脫硫石膏就可以替代天然石膏廣泛應用于水泥行業。

 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.

 中國硅酸鹽學會曾對珞璜電廠的脫硫石膏進行全面性能驗證試驗，試驗結果證明脫硫石膏用作水泥緩凝劑完全可行，脫硫石膏的各項性能指標均可以達到有關標準的要求，有些指標甚至還優于天然石膏，所以，脫硫石膏完全可以替代天然石膏。另外這種工藝技術簡單、易于實現。因此在水泥行業，脫硫石膏將會廣泛地得到使用。

 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。國內許多石膏板廠就用脫硫石膏作原料。

 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.

 在建筑行業，脫硫石膏也有巨大綜合利用的市場。另外，在生產化肥硫酸鉀方面，脫硫石膏也會得到廣泛使用。

 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.

 脫硫石膏首先立足于綜合利用，以保護環境，節約土地，避免資源浪費，并可產生一定的經濟效益。本工程采用干灰場，無法采用石膏水力拋棄處理方案，本工程脫硫石膏全部脫水后，運往綜合利用用戶。脫硫石膏無法綜合利用時，石膏脫水后由輸送皮帶運至電廠干灰場碾壓貯存。本工程6臺1190t/h鍋爐，鍋爐采用4運行2臺熱備用，考慮實際4臺鍋爐運行脫硫石膏排放量見表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.
