What are the main wearing parts of CFB boiler! How to do anti abrasion treatment

2021-03-24

With the rapid development of industry, environmental pollution and energy problems become more and more prominent. Therefore, a circulating fluidized bed boiler with high efficiency, low pollution, flexible regulation, wide adaptability to coal and high comprehensive utilization rate of slag has been invented.


Because of the characteristics of circulating fluidized bed boiler, it has been widely used in power plant and other industrial production. But also because of the characteristics of the circulating fluidized bed itself, the wear problem of the circulating fluidized bed boiler is more significant and serious. Therefore, for the use of circulating fluidized bed boiler thermal power plant, boiler anti-wear is the key.


Circulating fluidized bed boiler anti-wear not only improves the safety of industrial production, but also improves the stability, making production safer and work efficiency higher. Today Xiaobian and you talk about circulating fluidized bed boiler wear mainly occurs in which parts!


Circulating fluidized bed boiler wear mainly occurs in: membrane wall, superheater, economizer, air preheater, boiler Air Nozzle and castable.


These parts must be well protected against abrasion during boiler maintenance. If the abrasion is too serious, the boiler may shut down at any time. When the boiler is shut down, it means that the power plant can not continue to work, and the ultimate loss is the interests of the power plant.


In the field of circulating fluidized bed boiler anti-wear, we first introduced the active heat conduction grid anti-wear technology. This technology is different from the previous passive thickening anti-wear technology. It is to install alloy grid plates on the surface of water wall along the horizontal and vertical directions to form grid, reduce the velocity of material particles on the surface of water wall, block the formation of adherent flow, dredge the flow cycle of material on the surface of water wall, optimize the surface flow field and eliminate local vortex.


The construction scheme is designed according to the wear characteristics of different boilers, which can play the role of treating both the root cause and the root cause of the wear in the circulating fluidized bed boiler. Ensure the long-term operation of the boiler under high load, and increase the fuel adaptability of the boiler (such as increasing the proportion of gangue).
