Embodiment Construction
[0025] An internal flue gas baffle device of a horizontal waste heat boiler, such as figure 1 As shown, it includes horizontally arranged intertube baffles 1, side wing baffles 2, sleeves 3, and vertically arranged heating surface tube bundles 4, each heating surface tube bundle 4 is equipped with fins, and the adjacent intertube baffles 1 are connected by the connecting piece 5, the outer edge of the side baffle 2 is close to the inner wall 6 of the flue, and the two ends of the tube bundle 4 on the heating surface are connected with the header 7. The flue gas flow inside the horizontal waste heat boiler is constrained by the inter-tube baffle 1 and the side baffle 2, and scours the tube bundle on the heating surface laterally. The flue gas baffle is not directly welded to the 4 bundles of heating surface tubes, and the adjacent baffles are not directly welded, thus avoiding large stress and deformation due to thermal expansion.
