一切都需要清洁，燃气锅炉也不例外。 燃气锅炉长时间使用后，会粘附在内壁上。 水垢的出现将对燃气锅炉的加热效率有很大的影响，并且还会缩短燃气锅炉的使用寿命。 让我们看一下燃气锅炉的清洁步骤。
Everything needs cleaning, and gas boilers are no exception. After long-term use, gas boiler will adhere to the inner wall. The appearance of scale will have a great influence on the heating efficiency of gas-fired boiler and shorten the service life of gas-fired boiler. Let's take a look at the cleaning procedure of the gas boiler.
1. Clean water
After connecting the cleaning equipment and the gas boiler to be cleaned, water shall be injected into the boiler body of the gas boiler to circulate and clean the water for ten minutes. During the cleaning process, it is observed that the gas boiler leaks and the floating rust can be washed away.
2. Peeling and anti-corrosion cleaning
按比例向清洁槽的循环水中添加表面释放剂和缓释剂，并循环洗涤20分钟，以使剥离剂和污垢充分接触，以确保清洁效果。 同时，对没有水垢的物体表面进行防腐蚀处理，以防止结垢和清洁。 清洁剂腐蚀清洁组件。
Add the surface release agent and slow release agent to the circulating water of the cleaning tank in proportion, and wash for 20 minutes circularly to make the stripper and dirt fully contact, so as to ensure the cleaning effect. At the same time, anti-corrosion treatment shall be carried out on the surface of the object without scale to prevent scaling and cleaning. Detergent corrodes cleaning components.
3. Descaling and cleaning
Add a certain proportion of scale remover to the circulating water of the gas boiler cleaning tank for cleaning and descaling, and confirm that all scale can be cleaned.
4. Passivation coating treatment
Add the passivating coating agent to the circulating water of the gas boiler cleaning tank, and passivate the cleaning system to prevent the corrosion of pipes and components and the formation of new scale.
5. Circulating water cleaning
Flush the residual liquid in the gas boiler.
