Both risers are tightened and fixed by three steel wire ropes. Figure 1 As shown, a lifting lug 4 is provided on the top of the chimney 1. Figure 2 As shown, one end of the steel wire rope 3 is fixed on the first through hole 41 of the lifting ear 4, and the other end of the steel wire rope 3 is fixed on the ground.

[0004] Since the chimney riser and vent riser of the water jacket heating furnace are in the open air all year round, exposed to the sun and rain, the steel wire rope is aged and rusted, resulting in breakage, causing the chimney 1 to lose balance, posing a safety risk.
