How to do a good job of anti-wear circulating fluidized bed boiler

      Circulating fluidized bed boiler in many industrial production now more important production equipment, circulating fluidized bed boiler is not only efficient, but also more environmentally friendly and clean. But circulating fluidized bed boilers will still have other problems, our most common is the boiler anti-friction, anti-friction and explosion-proof work is the focus of the work of boiler workers and key work.

　　A domestic power plant 135MW and above, 22 CFB units of various capacities in 4 years, a total of 60 non-stop events, including circulating fluidized bed boilers because of wear problems leading to leakage non-stop 39, accounting for 65%, this proportion is still quite high, directly to the smooth production of the power plant has a huge impact. Directly affect the economic efficiency of the power plant, serious and may even produce production safety problems.

       Circulating fluidized bed boiler anti-wear technology

　　After years of technical research and innovation, we officially launched the grid anti-friction technology to the market in 2014. This anti-wear technology is a kind of active anti-wear technology to effectively control the wear problem of water-cooled wall by installing alloy grating plates along the surface of water-cooled wall in horizontal and vertical directions to form a mesh grating, blocking the formation of high-speed wall flow, optimizing the flow field on the surface of water-cooled wall, eliminating local vortex, reducing the speed of wall movement of gas-solid two-phase flow, and reducing the cutting force of material particles on water-cooled wall.

　　This technology has been applied in many large power plants, from low, medium and high pressure boilers to sub-critical and even super-critical CFB boilers, and there are successful cases of using our grille anti-wear technology, and the anti-wear transformation has achieved excellent anti-wear effect, which is highly praised by customers.
