品    名：锅炉停炉保护剂（十八胺乳液）

型    号：SGR1912

性能指标：

性能用途：停炉保护剂SGR1912用于机组的检修期的停用保护，也可以用于机组的较长期的停（备）用保护。在机组停炉前向水汽系统一次加入停炉保护剂，对停用机组有超过两年的长期防锈保护效果。该药剂还表现出一定的清除表面金属氧化物垢的能力，可减少锅炉结垢及清洁汽轮机叶片表面，并且停炉保护剂对机组再启动时水质无不利影响。

使用方法：在有条件时，可增设专用的停用防锈剂的加药系统（配备较大出力的加药泵和溶液箱）。在无条件增设专用加药系统时，可利用原有的给水加联氨系统和加磷酸盐系统。

具体使用操作程序：

①在机组滑停操作前，停止向炉水加磷酸盐以及停止向给水加联氨；

②在确定机组滑停操作开始后，滑停至合适的热力参数，如汽包压力8-9MPa，相应饱和温度300℃左右，过热蒸汽温度不高于500℃时，启动相关加药泵或相关阀门，向给水及炉水同时加入停炉保护剂，并在预定时间内加完药液；

③药液加完后，用除盐水冲洗溶液箱及加药系统管道，尽可能在次热力参数下稳定运行两小时，机组按正常停机过程滑停，并热炉排放炉水；

④按水汽系统的水容积计算，加药量150-250mg/L（按有效浓度计算）。。

包装与贮运：

25kg或50kg的塑料桶包装；在阴凉干燥处存放，并远离氧化剂和酸性物质。停炉保护剂在运输与存储过程中，必须严格防止受污染和混入杂质，室温存储12月以内。

安全与防护：

操作时注意劳动保护，应避免与皮肤、眼睛等接触，接触后立即用大量清水冲洗。

Boiler shutdown furnace protection agent

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.
