When arranging the baffle and plug-in doors, it should be carried out in the direction of the horizontal spindle as far as possible. The purpose of this is to ensure that flue gas baffles and plug-ins can be opened and closed smoothly to meet the operational requirements of the power station and flue gas fans. The installation of the flue baffle and the plug plate frame should be bolted and flanged, and it needs to be tightly connected to the flue through the flange. This connection ensures that the baffle and plug-in plate will not loosen or fall off during operation, thus ensuring the normal operation of the equipment. 
Baffles and inserts should be made of the appropriate grade of steel and need to be heat-treated. This increases the strength and durability of the material and ensures that the baffles and inserts will not deform or degrade during use. During the design of frames, shafts and supports for baffles and plug-ins, special attention needs to be paid to preventing dust ingress and deformation or degradation caused by high temperatures. The occurrence of these problems will directly affect the normal operation and service life of the equipment. All supports of the working gears of the shaft or baffle and plug plate should be lubricated with grease, which can reduce the wear and friction of the gears and prolong the service life of the equipment. At the same time, the end of the shaft should be equipped with a clear and easy to see mark indicating the position of the baffle, and it needs to be equipped with an interlocking limit switch to ensure the safe operation of the equipment. The material of the baffle and plug plate frames, plates and shafts installed in the clean flue should be made of stainless steel or better. This improves the corrosion resistance and service life of the equipment. Fasteners such as seals and bolts of the baffle should be made of alloy steel or better, and the outer parts can be made of ordinary carbon steel or better. The baffle frames, plates and shafts of the flue gas in the hot raw flue gas rather than the net flue gas can be made of carbon steel or better material. This improves the high temperature resistance and service life of the equipment. All fasteners used in baffles and plug-in doors are made of a material not lower than the parent material of the part to be fastened. This ensures the strength and longevity of the fasteners and avoids loosening or falling off.
The drive should be designed to take into account the expansion and contraction of the baffle in order to be able to accommodate this situation and maintain the normal operation of the equipment. The design of all baffles and plug plates should consider the convenience of on-site construction and detachable insulation structure, and avoid thermal unevenness. This can facilitate the installation and maintenance of the insulation structure by the construction personnel, and at the same time can also improve the use effect and service life of the equipment.
