More Information
Summary:The invention relates to preheater equipment, in particular to a special scale for mounting an air preheater sealing device, which comprises a scale plate, a measuring scale and a bubble type level indicator, and the upper edge of the scale plate is a curve outline mounting line for indicating the mounting position of the upper side of a radial hot end sealing piece. The invention aims to providea measuring scale for sealing installation of an air preheater, and provides a non-linear reverse deformation installation method. According to the nonlinear reversible deformation installation method, an informatization means is utilized, deformation is obtained according to a deformation curve, broken line segments are not needed any more, and more precise installation is adopted as a reversibledeformation installation curve. The installation method can further greatly reduce the air leakage gap. Partial mushroom-shaped deformation is counteracted, the air leakage rate of the air preheateris greatly reduced, the uni
