The internal parts of the boiler can be efficiently and benignly operated through cleaning, effectively eliminating the potential danger of accidents. After cleaning can effectively reduce the load of the pump, heat exchanger and other major components, reduce the wear and tear of operating parts, reduce the failure rate. If the boiler is cleaned and maintained regularly, it can extend the service life of the equipment for 3-5 years. It can improve the heating efficiency of the boiler and reduce gas consumption. Experiments show that after boiler cleaning can save 25%-30% of energy on the original basis.
Boiler is a heat transfer equipment, so in the process of heating and constantly injecting cold water will form scale, and scale will accumulate more and more, so that the heat transfer efficiency of the boiler will also be greatly reduced, the main performance of the boiler gas consumption increases, insufficient heating, sanitary hot water when the cold when hot, hot water, hot water, such as reducing the symptoms of a serious boiler liner will lead to the destruction of the boiler. So any one of the gas boiler in the use of t few years after it must be cleaned and maintained.
Generally speaking, large gas boilers need to be cleaned every 2 to 3 years, medium-sized gas boilers need to be cleaned every 3 to 5 years, and small gas boilers need to be cleaned every 4 to 6 years.
Boiler cleaning preparation: first of all, the boiler cleaning boiler structure, material and heat transfer method to understand. Put on the market to use dozens of boilers, each using the heat transfer method, structure and material are not the same, on different structures and different materials to take different ways of cleaning. To different regions, different water quality and different scale quality analysis and laboratory tests, for different materials and different scale quality, configuration of different chemical cleaning agents, develop scientific and reasonable cleaning program.
The first step of boiler cleaning: descaling cleaning. In the cleaning tank circulating water in proportion to the addition of configured descaling cleaning agent, boiler cleaning and descaling, according to the amount of scale to determine the amount of cleaning cycle time and how much to add chemicals, to confirm that all the scale cleaned down to the next step in the cleaning program.
Boiler cleaning step two: water cleaning. After connecting the cleaning equipment and the boiler, the water cycle should be cleaned for 10 minutes to check the status of the system, whether there are leaks, and at the same time, the floating rust will be cleaned off.
Boiler cleaning step 3: stripping anticorrosion cleaning. Proportionally in the cleaning tank circulating water added to the surface stripping agent and slow release agent, cyclic cleaning for 20 minutes, so that the separation of scale and cleaning of the various components, and at the same time no scaling of the surface of the object anticorrosive treatment to prevent descaling cleaning cleaning cleaning agent corrosion on the cleaning parts. Boiler cleaning step 4: passivation coating treatment. Add passivation coating agent, boiler cleaning system for passivation coating treatment, prevention and control of corrosion of pipelines and components as well as the generation of new rust scale
