In operation, pouring materials are used for filling the parts with obvious smoke leakage, but the effect is not obvious. Through preliminary analysis, especially, the flue gas leakage at the wall penetrating part of the superheater pipe and the wall penetrating part of the support hanger is most obvious. The original designed furnace top castable is fixed by using a steel bar grid, and because the steel bar grid expands at high temperature due to large expansion amount, the refractory material on the outer layer of the grid is easy to expand and crack to generate cracks, and the steel bar grid is corroded by high-temperature corrosion to cause the castable to fall off; due to the frame of the furnace top, hooks for connecting the reinforcing steel bar grids are sparse, and the reinforcing steel bar grids cannot bear the self weight of the casting material, so that the falling is generated, and the furnace top collapses.
The flue gas leaked from the furnace top penetrates out of the wall penetrating pipe, and the furnace top is not sealed by metal or specially designed furnace top; cracks are certainly generated in the thermal expansion of the casting material, and the thermal expansion amount of the wall-penetrating pipe and the like is much larger than that of the casting material, so that an aluminum silicate fiber blanket is directly made on the casting material after the casting material is made in the original design, and special treatment is not designed, so that the smoke gas leakage and ash leakage of the furnace top are caused.
