2.4当水压上升至工作压力时，应暂停升压，检查个部分有无漏水，然后再升至试验压力保持20分钟，回降至工作压力，在进行检查。水压试验用水应保持高于周围露点温度，以防蒸发器表面结露，也不宜温度过高，以防引起汽化和过大温差应力，一般为20～70℃。
2.4 When the hydraulic pressure rises to the working pressure, stop boosting pressure temporarily, check whether any part leaks water, then boost it to the test pressure and keep it for 20 minutes and then reduce it to the working pressure to inspect. The water of hydraulic pressure test should be kept higher than the surrounding dew-point temperature to avoid the condensation of evaporator surface; it should not be too high in order to avoid the vaporization and too big temperature difference stress. The temperature should be generally within 20～70℃.

4.4 During the hydraulic pressure test, forbid the unconcerned personnel to involve. If individual is found to leak during the test, it is allowed to keep boosting the pressure, but forbid anyone from entering the equipment to inspect when boosting the pressure.
七． 煮炉前的检查
Inspection before boiling furnace
在烘炉和煮炉前，必须检查装置的各部件，检查项目如下：
Before drying and boiling the furnace, it is required to inspect all parts of the device and the inspection items are as follows:
1. 烟气通道耐火材料有无脱落。
1. Whether the refractory material of flue gas passage drops off.
2. 各处阀门、仪表开启位置是否正确。
2. Whether the opening positions of all valves and instruments are correct.
3. 出水管路、回水管路及排污管路是否完整。
3. Whether the water outlet pipeline, the water return pipelines and the drainage pipeline are complete.
八． 烘炉和煮炉
Furnace drying and boiling
1. 新装置在使用前应进行烘炉和煮炉。其目的是使装置内的耐火材料及保温材料能缓慢的干燥起来，在正常使用时不致损裂。煮炉的主要目的是为了消除装置内部的杂质和油垢，煮炉时装置内部要适量加入药品使炉水成为碱性，以去除装置内部的油污及杂物。
1. The new device should dry and boil the furnace before use for the purpose of drying the refractory materials and heat insulation material within the device slowly so as to avoid damage and crack during normal use. The main aim of boiling furnace is to remove the impurity and oil sludge within the device; when boiling the furnace, the appropriate amount of drug is added into the device to make the furnace water alkaline so as to remove the oil sludge and impurity within the device.
华译网上海翻译公司曾经翻译过大量有关安全措施及注意事项资料文件，Beijing Chinese Subtitling Translation Service Agency has translated many technical documents about Safety measures and notice.
2. 煮炉可采用纯碱（Na2Co3）或磷酸三钠（Na3Po4）等药品。药品加入量前者为8Kg/m3，后者为5Kg/m3，应配置均匀，不得将固体药直接加入炉内。
2. Boiling furnace can adopt sodium carbonate (Na2Co3) or trisodium phosphate (Na3Po4) or other drug. The adding amount is 8Kg/m3 for the former and 5Kg/m3 for the latter. They should be well-distributed and it is forbidden to add the solid drug into the furnace directly.
3. 将配好的溶液加入锅炉内，然后关闭各处阀门，开启一只安全阀，使空气可以排出。
3. Add the prepared solution into the boiler, close all gates and open one safety valve to exhaust the air.
4. 加入水的温度不应高于40℃，并检查各处有无渗漏现象。
4. The temperature of the added water should not be higher than 40℃; check whether there is any leakage for all parts.
5. 用木柴烘炉六小时后，进行系统升温，使压力上升到2.5Mpa，维持12小时，然后停止升温，待水温降至70℃以后打开排污阀将炉水放净。
5. Six hours after drying the furnace with the firewood, raise the system temperature and boost the pressure to 2.5Mpa and keep it for twelve hours and then stop raising the temperature. After the water temperature is lowered to 70℃, open the drainage valve and discharge all boiler water.
九． 调整安全阀
Safety valve adjustment
安全阀在初次生火时应进行调整（运转时每年至少进行一次调整和校验），按《热水锅炉安全技术监察规程》第八章和第105条表8-1规定压力进行调整。
The safety valve should be adjusted for the first time of making a fire according the pressure specified in Table 8-1 of Article 105 and Chapter VIII of Regulations on Heat Water Boiler Safety and Technical Supervision (the adjustment and verification is required once a year when the device is put into operation).
1. 安全阀的调整方法：拆去开口销，除去顶盖，放松六角锁紧螺母，然后旋动调节螺杆，使弹簧放松或拧紧，来达到安全要求的排放压力，调整后旋紧螺母，在将其余零件安装。
1. The adjusting method of safety valve: dismantle the split pin, remove the top cover, loosen the hexagonal lock nut and then revolve the adjustment screw to loosen or tighten the spring to reach the relieving pressure required by the safety. After adjustment, tighten up the nut and then install other components.
2. 安全阀的开启压力，锅炉工作压力为2.35Mpa表压时，安全阀的开启压力调整到2.5Mpa表压。
2. When the open pressure of the safety valve and the working pressure of the boiler are 2.35Mpa gauge pressure, adjust the open pressure of the safety valve to 2.5Mpa gauge pressure.
3. 所有安全阀经校验后，应加锁或铅封，严禁任意提高安全阀的开启压力或使安全阀失效。
3. After verification, all safety valves should be locked or lead sealed. Forbid increasing the open pressure of the safety valve or making the safety valve fail to work.
4. 安全阀校验后，开启压力、回座压力、阀芯提升高度等校验结果，应记入锅炉技术档案。
4. After the safety valve is verified, the verification results of open pressure, reseating pressure, lifting height of the valve core should be record in the file of boiler technology.
5. 安全阀未经校验前，设备绝对禁止投入运行。
