Flue gas sealing baffle plate between pressure part modules of waste heat boiler

The utility model relates to a flue gas sealing baffle plate between pressure part modules of a waste heat boiler. The utility model is characterized in that flue gas sealing baffle plate comprises a horizontal sealing baffle plate fixed between the pressure part modules, wherein the horizontal sealing baffle plate is fixedly connected with a vertical baffle plate, the bottom of the vertical baffle plate is arranged in a lower limit stop, the lower limit stop is arranged on a wall board, and the lower limit stop, the vertical baffle plate and the wall board are not fixed. The flue gas sealing baffle plate has the advantages that the vertical baffle plate is supported by the horizontal sealing baffle plate, so the boiler is not easy to distort in the operation; the lower limit stop, the vertical baffle plate and the wall board are not fixed, thereby being favorable for the vertical battle plate to expand all around; the upper limit stop is removed, and the vertical baffle plate can be thinned, thereby saving t
