Anti-wear program for circulating fluidized bed boilers in thermal power plants

      With the rapid development of industry and the increasingly tense situation of environmental protection, circulating fluidized bed boilers (cfb boilers) have slowly replaced traditional boilers because of their high efficiency, energy saving and environmental protection characteristics. Circulating fluidized bed boiler is especially suitable for thermal power plants, although China is currently rich in power resources, but because of various factors, thermal power generation still occupies a major position. Especially in the winter peak electricity consumption, many areas can only rely on thermal power to maintain supply.

　　Although circulating fluidized bed boilers have many points of their own and are highly favored by thermal power plants. But also because of the characteristics of circulating fluidized bed boiler itself, the boiler is easy to wear. Serious wear and tear will appear burst tube, furnace shutdown events, wear and tear seriously restrict the long-term safe and stable operation of circulating fluidized boilers. The most direct impact of furnace shutdown is that the thermal power plant can not carry out normal production, not only affect the economy will also have a serious safety production accidents.

　　Circulating fluidized bed boiler wear caused by bursting tube shutdown, has been a difficult problem for thermal power plants to solve. Many companies have introduced spraying anti-wear technology, but spraying at the beginning of the boiler can indeed effectively solve the problem of wear, in about a year there will be problems such as shedding, aggravating the wear of the boiler.

　　In order to solve the circulating fluidized bed boiler wear problem, we have researched circulating fluidized bed boilers in many power plants and found that the grid anti-wear technology can effectively solve the circulating fluidized bed boiler problem for a long time.

　　Compared with the previous spraying type anti-wear, it is more stable and durable, which greatly delays the life of the boiler and ensures safe and smooth daily operation of the boiler.
