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

      Circulating fluidized bed boilers have become one of the main equipment in thermal power plants because of their energy efficiency and environmental friendliness compared to other boilers. Circulating fluidized bed boiler is not perfect, it also has the problem of easy wear and tear. Wear problems have been plagued by thermal power plants, serious wear leads to thermal power plant boiler leakage or even burst tube. In this regard, the study of circulating fluidized bed boiler wear problem is of great significance.

　　Circulating fluidized bed boiler anti-wear most serious place is the water-cooled wall, the general water-cooled wall wear are due to high-speed operation of the fuel particles for a long time caused by the scouring. The initial wear and tear may not bring actual economic impact to the power plant, but due to the long-term wear and tear is not paid attention to and found, resulting in the wear surface is getting bigger and bigger, it will form a leak or even burst tube.

　　After years of research and discovery, we at Wuhan Yongping Technology like major companies have launched the grille anti-wear technology. This technology is a kind of active anti-wear technology, is in the water-cooled wall surface along the horizontal and vertical direction, installed alloy grating plate to form a mesh grating, block the formation of high-speed wall flow, optimize the water-cooled wall surface flow field, eliminate local vortex, reduce the velocity of the two-phase flow wall movement, reduce the cutting force of material particles on the water-cooled wall.

　　Wuhan Yongping grating anti-wear technology has been applied in many large power plant boilers at home and abroad, the anti-wear effect is good, successfully solving the boiler wear problems in thermal power plants, and has been praised by the power plants.
