How can boiler cleaning remove dirt
Boiler is used in electric power industry, manufacturing industry, textile and chemical fiber industry. After a long period of operation of the boiler, scale and rust problems will occur. The reason for the formation of scale is that the substances in the water will undergo physical and chemical reactions in the boiler under high temperature and pressure, and eventually form hard and dense scale on the heating surface. To remove the scale, the boiler must be cleaned.
The purpose of scale removal is to save fuel and not waste fuel. Scale is the main cause of boiler accidents. The accumulated scale in the heating area of the boiler will block the heat transfer of the boiler. If the scale is removed, the heating problem will be solved, and there will be no boiler accidents. The advantage of scale removal is that the boiler can operate without scale, and the fuel consumption will be reduced. The cost of boiler cleaning and maintenance is correspondingly reduced to avoid potential safety hazards such as corrosion, deformation, leakage, etc. due to boiler scaling. The service life of boilers without scaling is also greatly extended, and there will be no loss caused by shutdown due to repair.
How to remove the scale in the boiler can be physically cleaned by high-pressure water jet. The water pressurized by the equipment pressurization system is ejected from the nozzle to form a high-speed water jet, which has a high impact and exploitation power and can remove the scaling on the inner wall of the boiler. Chemical methods can also be used for boiler cleaning, that is, add cleaning agent in the boiler, and a proper amount of cleaning agent will react with the scaling in the boiler, and the scaling will easily fall off. When cleaning agent is used, it should be suitable, which can remove dirt effectively. Which kind of cleaning agent is good? Choose the cleaning agent to use.
For boilers that have been used for a long time, the dirt accumulated inside is relatively stubborn. It is difficult to remove the dirt only by physical cleaning with high-pressure water, which requires the combination of chemical and physical methods to achieve better removal effect. If the dirt cannot be removed even after using the cleaning agent, the cleaning company should be considered to find the cleaning service to clean the dirt in the boiler without damaging the boiler. Cleaning company Yes, it has cleaning technology and equipment to remove dirt, so the cleaning efficiency is higher. Now there are many cleaning companies, and they can find satisfactory boiler cleaning services. This company has strong strength and good service quality. It can remove the dirt in the boiler and ensure the normal operation of the boiler.
The production team with high-tech production technology and high-tech production equipment is the guarantee for the performance of our detergent products. Honesty, customer first, energy conservation and environmental protection have always been our corporate tenet. Industrial boilers have been used for a long time. Due to poor boiler water quality. It often leads to heating surface structure. Structure phenomenon will greatly reduce the heat conduction efficiency of water treatment boiler. Long term overheating of the heating surface will lead to internal damage of the boiler: tube explosion, tube explosion, bulge, falling off of the inner wall structure and other problems. On the other hand, long-term non treatment will cause metal corrosion. Therefore, it is very important to do a good job in boiler water treatment. Our boiler cleaner manufacturer recommends that you use boiler cleaner, boiler descaling agent and other water treatment agents. Avoid heat conduction efficiency reduction and energy waste caused by boiler structure. Avoid problems such as boiler and perforation caused by long-time non treatment. The reduction of boiler strength will cause safety hazards for our work.
The process of boiler cleaning and passivation is actually a process of re reaction between the clean boiler body surface and the passivator. Because the control point requirements for passivation are relatively strict. If the control is not good. Passivation will fail. Some owners of boiler cleaning do not understand the essence of passivation. So. Some small cleaning companies pursue benefits. Save materials. Often only simple neutralization is carried out after pickling. The cleaning is over. This will cause secondary floating rust on the cleaned boiler surface. The scale inhibition capacity of the boiler decreases. It is easy to rust. The improvement measures are. After boiler acid cleaning. Rinse and passivate. Because the passivation process requirements are relatively strict. The concentration of total iron ion shall be strictly controlled during rinsing.

Different anaerobic sludge also has a certain impact on the startup of the reactor. When the anaerobic reactor sludge that does not treat wastewater of the same nature is used as seed sludge, anaerobic digestion sludge or feces can be considered. The temperature has an important influence on the startup and stability of the U: SB system. U: The SB reactor can be started successfully at normal temperature (25 ℃), medium temperature (33 ℃~41 ℃) and high temperature (55 ℃), and granular sludge can be formed. However, most of the studies on the startup process of U: SB were carried out under moderate temperature conditions, and there were a few reports on low temperature startup.
