How to choose the wear-resistant material for the separator of circulating fluidized bed boiler?

In recent years, with the expansion of coal application scope and the enhancement of people's environmental protection awareness, circulating fluidized bed boiler, as a main "clean combustion" device, has been widely used, which shows its strong development momentum. For the selection of wear-resistant materials for the separator of the circulating fluidized bed boiler, it is not only based on the technical indicators under the normal operating conditions, but also on the anti-wear strength and fire resistance under the actual operating conditions of the circulating fluidized bed boiler. How to deal with this problem effectively, Jiangsu Sifang boiler suggests:

1. Operating condition environment of separator

The separator is an important component of high-efficiency separation in circulating fluidized bed, and its performance directly affects the performance of the boiler. The working temperature of this part is about 900 ℃, the inlet flow rate of flue gas is high (30M / s), the ash concentration is high, the abrasion is serious, and the refractory material on the top is easy to fall off. Especially, the erosion and impact of fly ash particles in the inlet flue and the target area are more serious, and the internal operating environment is extremely bad.

2. Selection of wear resistant materials in separator

For the adiabatic separator, in order to ensure the normal operation of the separator, the selection of internal wear-resistant castable performance is particularly important. Through many years of research and development and operation of circulating fluidized bed, our company has developed relevant internal control standards for the wear-resistant materials of the separator according to the target area and non target area, meeting the safe operation requirements of the boiler and reducing the operation failure rate.
