What are the main wear parts of circulating fluidized bed boilers! What to do for anti-wear treatment

      With the rapid development of industry, environmental pollution and energy problems are becoming more and more prominent. Therefore, circulating fluidized bed boilers, which are more efficient, less polluting, flexible in regulation, widely adaptable to coal types, and have a high comprehensive utilization rate of slag, have been invented.

　　Because of the characteristics of circulating fluidized bed boiler, it has been very widely used in power stations and other industrial production requiring boilers. But also because of the characteristics of circulating fluidized bed itself also determines the circulating fluidized bed boiler wear problem is more significant and serious. Therefore, for thermal power plants using circulating fluidized bed boilers, boiler wear prevention is the focus.

　　Circulating fluidized bed boiler anti-wear not only improves the safety of industrial production, but also improves the stability, so that production is safer and more efficient. Today I talk to you about the circulating fluidized bed boiler wear mainly occurs in which parts!

　　Circulating fluidized bed boiler wear mainly occurs in: membrane wall, superheater, coal conservator, air preheater, air cap and casting material.

　　These parts in the usual boiler maintenance must do a good job of anti-wear treatment, if the anti-wear is too serious at any time may lead to boiler shutdown. Stopping the furnace means that the power plant can not continue to work, the ultimate loss is the interests of the power plant.

　　In the field of circulating fluidized bed boiler anti-friction, we first introduced the active heat-conducting grill anti-friction technology. This technology is different from the previous passive thickening anti-wear technology, it is installed in the water-cooled wall surface along the horizontal and vertical direction, alloy grating plate to form a mesh grating, reduce the speed of material particles on the surface of the water-cooled wall, block the formation of wall flow, and channel the flow of material on the surface of the water-cooled wall, optimize the surface flow field to eliminate local vortex flow.

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