CFB boiler anti-wear technology application

      Circulating fluidized boiler is the main equipment of thermal power plant production process, it is more energy-saving and environmental protection compared with other traditional boilers. It is able to meet the environmental protection policy of the status quo everywhere and has better applicability.

　　Although circulating fluidized bed boilers have many advantages over traditional boilers, but also because of its own characteristics lead to circulating fluidized bed boilers are easy to wear. If long-term wear and tear is not dealt with, it may lead to boiler shutdown. This not only affects the normal operation of the power plant and affects the economic efficiency, but also seriously affects the safety of life.

　　So for thermal power plants, boiler anti-wear is very meaningful. Not only can improve the production safety efficiency, but also can improve the economic efficiency, for thermal power plants to kill many birds with one stone.

　　After years of research, we, Wuhan Yongping, introduced the grid anti-wear technology to thermal power plants in 2014. This technology efficiently solves the wear problem of circulating fluidized bed boilers, which not only makes the boilers of thermal power plants operate more smoothly, but also greatly extends the life cycle of the boilers.

　　Our grille anti-wear technology is an active anti-wear technology, which is installed on the surface of the water-cooled wall along the horizontal and vertical directions to form a mesh grille, blocking the formation of high-speed wall flow, optimizing the flow field on the surface of the water-cooled wall, eliminating local eddy currents, reducing the velocity of the wall movement of the gas-solid two-phase flow, and reducing the cutting force of the material particles on the water-cooled wall.

　　The grille anti-wear technology has been applied to more than 200 boilers at home and abroad, including supercritical and ultra-supercritical boilers. It has completely solved the problem of boiler wear and tear leading to furnace shutdown, and is highly favored by power plants.
