Circulating fluidized bed boiler heating surface wear solutions

      With the rapid development of China's industry, circulating fluidized bed boiler is more and more widely used. Because of its ability to desulfurize within as well as efficient combustion and other characteristics, it has been widely used in China's thermal power and other industrial industries, and the effect is better compared to traditional boilers.

　　Because of the design, operation and daily maintenance and other factors, circulating fluidized bed boilers have a persistent problem - wear and tear leakage problem. Circulating fluidized bed boiler wear and tear over time, will directly reduce the service life of the boiler, greatly reducing the operating efficiency, greatly increasing maintenance costs, and seriously and directly affect the safety of production.

　　So for the use of circulating fluidized bed boiler enterprises, boiler wear prevention problems can not wait.

　　Circulating fluidized bed boiler combustion, fuel in the furnace repeatedly cycle combustion, until burned out, so the fuel particles in the furnace residence time is long. In the boiler operation process, the ash-containing airflow in a certain operating angle and speed, and the heating surface of the impact, it will be the heating surface of the fine metal chips cutting off, thus producing wear on the tube wall. Boilers in the furnace water-cooled wall, superheater tube screen, the tail convection flue, external heat exchanger and other heating surfaces suffered more serious wear.

　　After years of research, we have found that the grid anti-wear technology can effectively solve the wear problem of circulating fluidized bed boilers. This technology is an active anti-wear technology, compared with the traditional spray anti-wear, the grille anti-wear is more stable and durable.
