After a period of two months, a blast pipe of the left wing-shaped water-cooled wall pipe in the hearth, four bulges and bulges were deformed and repaired and replaced 7 after a newly installed DZL1.4-0.7 / 95/70 boiler was installed in a dry- Root water wall tube. After a month of operation in the original three rupture tube position of a squib. In order not to affect the heating had to cut off blind death, the end of the heating period, the left wing-shaped water wall tube cut a total of 3 dead, and another three bulge deformation. After stopping the furnace into the drum and header check found that the boiler water side of the knot scale average 1mm, coverage 80%, the left header central accumulation of slag slag height 60mm, right header box no tablets, the left bottom of the drum slag Stacked 130mm thick, there is sporadic tab on the left, check the water through the water wall tube and found the left before the number 2,3,4,5,
