Circulating fluidized bed boiler water-cooled wall high-efficiency anti-wear technology

      Circulating fluidized bed boiler, also known as CFB boiler, is one of the more important equipment in China's industrial production. Especially thermal power generation, large chemical plants are applied to circulating fluidized bed boilers, because of its efficient, clean, environmentally friendly characteristics and is widely used in industrial production.

　　But circulating fluidized bed boilers are not perfect, circulating fluidized bed boilers because of the wide range of fuel adaptability, the general use of fuel is not particularly high quality which will lead to boiler wear. Circulating fluidized bed heating surface water-cooled wall wear problem has been plagued by the safe operation of the boiler production.

　　From minor wear and tear to serious tube bursting and furnace shutdown. Furnace repair not only affects the normal order of production, but also directly affects the economic benefits of enterprises, circulating fluidized bed boiler water-cooled wall anti-wear urgently.

　　Traditional water-cooled wall anti-wear are used in the spray anti-wear, the technology began to anti-wear effect is quite okay, but in the boiler continuous use of time within a year, there will be peeling, skinning and other phenomena, resulting in increased local wear. In the long run, the effect of spraying type anti-wear is not ideal.

　　After years of research, we found that the grid anti-wear technology can be a very effective solution to circulating fluidized bed boiler wear. Compared with the traditional spraying anti-wear technology, the grid anti-wear technology is an active anti-wear technology, which is more durable, safe and stable, not only solving the circulating fluidized bed boiler wear problem, but also greatly extending the service life of the boiler.
