[0002] In a waste incinerator, there are usually superheated pipes, water-cooled pipes, and evaporators, which are arranged at key positions in the furnace. The superheated pipes, water-cooled pipes, and evaporators waiting for protection will be scoured by flue gas in the furnace, and a series of complex and continuous corrosion reactions will occur on their surfaces, such as pure gas corrosion, molten salt corrosion, gas corrosion involving solid phase attachments, and molten salt corrosion involving corrosive gases. In order to reduce the occurrence of corrosion of the superheated pipe waiting for protection parts by flue gas scour, stainless steel slips are usually installed outside the superheated pipe waiting for protection parts in the prior art to protect the pipeline. The installation process is as follows: first, the stainless steel slips are attached to the side wall of the superheated pipe waiting for protection parts facing the air outlet, and then the stainless steel slips are fixed to the superheated pipe waiting for protection parts by welding. Stainless steel slips are easily corroded and damaged under long-term erosion of flue gas, losing their protective effect. Moreover, two workers are required to participate in the welding of stainless steel slips. One worker holds the stainless steel slips while the other worker performs welding to fix the stainless steel slips on the superheated pipe waiting protective parts. The installation method of fixing the stainless steel slips on the superheated pipe waiting protective parts by welding is not suitable for one worker to operate, and there are problems such as inconvenient installation and increased labor cost expenditure.
