Anti-wear measure used in circulating fluidized bed combustion boiler

Boiler using circulating fluidized combustion, the combustion system, there are a lot of recyclable materials, the combustion system and the heating surface of the rear wear is essential in CFB boilers manufacturer.
The amount of smoke generated by burning furnace reasonable selection of cross-sectional area, the flue gas within a reasonable range speed control, can significantly reduce the wear of the furnace heating surface. Flue gas flow in the tail shaft, despite the low ash content flue gas, but with the flue gas temperature decreased, the hardness increase in gray, select the appropriate flue gas velocity convection heating surface to prevent wear and tear is an important measure for the 75 ton CFB steam boiler to Sri Lanka.
Casting furnace air distribution plate 70mm thick phosphate refractory concrete, cone section of the furnace water wall area around the welded pin on the tube, and laying 60mm thick (from the pipe center line) can wear fire-resistant plastic. Vertical segment in the cone section and the transfer of the area, water wall tubes of local processing.The lower part of the furnace water wall wear layer of the junction with the upper chamber 250mm welded within the area of the spoiler fins to vortex shredding.
Also, wear fins above requirements gas side polished weld pipe, weld residual height of not more than 1mm. The upper back wall of the flue gas exit furnace water wall tube around the surface, laying 60mm thick can wear fire-resistant plastic to prevent wear and tear gas flow to change the tube in the region.
Imports of flue cyclone, cyclone and cyclone exit flue casting material used in inner wear, set the high-density "Y" catch nail to be fixed, wear-resistant materials to ensure a solid and reliable. Wear in the construction process requires the surface flat and smooth transition.
