Causes and preventive measures of water-cooled wall wear in circulating fluidized bed boilers

       Circulating fluidized bed boiler is currently one of the main production equipment of thermal power plants, the problem of circulating fluidized bed boiler wear and tear has been plagued by thermal power plants. Not only affects the normal operation of the power plant, serious and even production safety accidents may occur.

　　Circulating fluidized bed boiler water-cooled wall wear

　　Water-cooled wall is the main heating surface of circulating fluidized bed boiler, water-cooled wall wear is one of the most serious parts of circulating fluidized bed boiler wear. And the longer the boiler runs, the more serious and prominent the problem of boiler water-cooled wall tube wear.

　　Many thermal power plants have taken a variety of methods are not effective, because the water-cooled wall wear led to the shutdown of things in the thermal power plant is not uncommon.

       Anti-wear technology

　　After years of research and discovery, we have withdrawn the grille anti-wear technology to major enterprises using circulating fluidized bed boilers.

　　Grating anti-wear technology is an active anti-wear technology that is installed with alloy grating plates along the horizontal and vertical directions on the surface of the water-cooled wall to form a mesh grating, 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 gas-solid two-phase flow against the wall, and reducing the cutting force of material particles on the water-cooled wall, so as to effectively control the wear problem of the water-cooled wall.

　　This technology has been applied to more than 200 boilers in many large enterprises, perfectly solving the wear problem of circulating fluidized bed boilers.
