[0002] The copper smelting technology of oxygen-enriched double-side blown molten pool smelting plus multi-spray gun top blown continuous blowing has the characteristics of good continuity and strong raw material adaptability, but the flue gas temperature generated thereby is as high as 1300 DEG C, and the sulfur content is close to 30%. Higher requirements are put forward for the overall air leakage rate and heat preservation performance of the waste heat boiler for flue gas heat recovery.

[0003] The radiation chamber of the bedroom waste heat boiler is provided with a flue gas baffle, which effectively optimizes the dynamic field and temperature field in the furnace and plays a crucial role in stabilizing various parameters of the boiler. The flue gas baffle penetrates into the interior of the boiler from the ceiling of the radiation chamber through the wall. Due to the high temperature inside the boiler, the flue gas baffle will expand horizontally and vertically after being heated. Therefore, a certain gap needs to be left between the flue gas baffle and the waste heat boiler to prevent the flue gas baffle from expanding and pressing the waste heat boiler, thereby causing damage to the waste heat boiler. To prevent leakage of flue gas in the waste heat boiler, ceramic fiber felt is usually filled in the gap, but the sealing performance of ceramic fiber felt is insufficient, and leakage often occurs at the connection between the flue gas baffle and the ceiling of the radiation chamber during actual operation due to poor sealing, causing equipment damage or environmental pollution, which is not conducive to the overall sealing and safe operation of the boiler.
