Pulverized coal concentrator cone, which is widely used in thermal power plants, has the advantages of high entrainment rate, short range and easy control of slagging and corrosion in furnace.But in the process of operation, the cone of wear-resistant coal concentrator made of heat-resistant steel is worn seriously under the strong erosion of coal powder and the pulverized coal dense thin separation consequence is greatly affected, so that the pulverized coal is given unevenly, the burnout degree is reduced, the low load combustion stability is poor, and the thermal efficiency of the boiler is reduced, which directly affects the safe operation of the boiler.
On the basis of many years of research and practice,the wear-resistant ceramic liner which can be applied to the cone of pulverized coal concentrator from BOMAI has been successfully developed.The main principle is to protect the cone with wear-resistant ceramic lining on the premise of keeping the cone size unchanged, so as to prolong the service life of the cone. Using high temperature adhesive to stick the ceramic to the cone can ensure that the wear-resistant ceramic will not fall off for a long time.It has been proved that the service life of this product can reach more than 4 years.
