It mixes with the flue gas to cool it down, preventing the flue gas temperature from being too high, which may cause damage to the internal equipment of the waste heat boiler, thereby improving its safety. When it is necessary to adjust the flue gas circulation speed inside the temperature regulating box 1, start the servo motor 22 to drive the screw 19 to rotate, the screw 19 drives the L-shaped plate 21 to move through the movable sleeve 20, the L-shaped plate 21 drives the gear 18 to rotate, and the gear 18 drives the adjustment plate 9 to rotate through the rotating shaft 8, thereby adjusting the size of the flue gas circulation channel opening inside the temperature regulating box 1.

By setting the adjustment plate and the driving mechanism, the flue gas circulation speed inside the temperature regulating box can be adjusted, so that the flue gas can be fully mixed with the cold air, thereby improving its temperature control efficiency.
