品 名：鍋爐停爐保護劑（十八胺乳液）
型 號：SGR1912
性能指標：
性能用途：停爐保護劑SGR1912用于機組的檢修期的停用保護，也可以用于機組的較長期的停（備）用保護。在機組停爐前向水汽系統一次加入停爐保護劑，對停用機組有超過兩年的長期防銹保護效果。該藥劑還表現出一定的清除表面金屬氧化物垢的能力，可減少鍋爐結垢及清潔汽輪機葉片表面，并且停爐保護劑對機組再啟動時水質無不利影響。
使用方法：在有條件時，可增設專用的停用防銹劑的加藥系統（配備較大出力的加藥泵和溶液箱）。在無條件增設專用加藥系統時，可利用原有的給水加聯氨系統和加磷酸鹽系統。
具體使用操作程序：
①在機組滑停操作前，停止向爐水加磷酸鹽以及停止向給水加聯氨；
②在確定機組滑停操作開始后，滑停至合適的熱力參數，如汽包壓力8-9MPa，相應飽和溫度300℃左右，過熱蒸汽溫度不高于500℃時，啟動相關加藥泵或相關閥門，向給水及爐水同時加入停爐保護劑，并在預定時間內加完藥液；
③藥液加完后，用除鹽水沖洗溶液箱及加藥系統管道，盡可能在次熱力參數下穩定運行兩小時，機組按正常停機過程滑停，并熱爐排放爐水；
④按水汽系統的水容積計算，加藥量150-250mg/L（按有效濃度計算）。。
包裝與貯運：
25kg或50kg的塑料桶包裝；在陰涼干燥處存放，并遠離氧化劑和酸性物質。停爐保護劑在運輸與存儲過程中，必須嚴格防止受污染和混入雜質，室溫存儲12月以內。
安全與防護：
操作時注意勞動保護，應避免與皮膚、眼睛等接觸，接觸后立即用大量清水沖洗。
Name: Boiler shutdown protective agent (amine emulsion)
Model number: SGR 1912
Performance index:
Performance use: the furnace stop protection agent SGR1912 is used for the stop protection of the unit maintenance period, and can also be used for the long-term stop (standby) protection of the unit. Add the furnace shutdown protective agent to the water vapor system before the unit furnace shutdown, which has a long-term rust prevention and protection effect on the unit for more than two years. The agent also shows a certain ability to remove the surface metal oxide scale, can reduce the boiler scale and clean the steam turbine blade surface, and stop the furnace protective agent has no adverse impact on the water quality when the unit is restarted.
Use method: when conditions permit, a special dosing system for stopping rust prevention agent (equipped with a large dosing pump and solution box can be added). When the special dosing system is added unconditionally, the original water feeding system and phosphate feeding system can be used.
Specific use of operating procedures:
① Stop adding phosphate to the furnace water and stop adding the ammonia to the feed water before the sliding stop operation of the unit;
② After determining the sliding stop operation of the unit, the sliding stop to the appropriate thermal parameters, such as the drum pressure of 8-9MPa, the corresponding saturation temperature is about 300℃, the superheated steam temperature is not higher than 500℃, start the relevant dosing pump or related valve, add the shutdown protective agent to the supply water and furnace water at the same time, and add the drug liquid within the predetermined time;
③ After adding the liquid, wash the solution box and the dosing system pipeline with desalinated water, and run stably for two hours under the secondary thermal parameters as far as possible. Stop the unit according to the normal shutdown process, and discharge the furnace water from the furnace;
④ According to the water volume of the water vapor system, 150-250 mg/L (calculated by effective concentration).
Packaging and storage:
25kg or 50kg plastic barrels; store in a cool, dry place and stay away from oxidants and acid. In the process of transportation and storage, the furnace stop protective agent must be strictly prevented from contamination and mixed with impurities, and must be stored at room temperature within 12 months.
Safety and Protection:
Pay attention to labor protection during operation, avoid contact with the skin and eyes, and rinse with a lot of water immediately after contact.
