Abstract:
A method for adding additional axial seals and radial seals within existing air preheaters. The installed heat transfer baskets, radial seals, axial seals, gratings, and stay plates are all removed from the air preheater. An intermediate diaphragm plate is positioned in each original compartment, mounted to the rotor shell and a diaphragm inner support plate. Hot and cold end plates mounted to the post and an inboard portion of the diaphragm plates forming the original compartment provide additional support. New gratings and/or stay plates are installed. Additional hot and cold end axial seal support bars are mounted to the rotor shell and intermediate diaphragm plate. Axial seals are installed on the original and additional axial seal support bars and radial seals are installed on the axial edges of the original and intermediate diaphragm plates. Finally, new heat transfer baskets are inserted into each of the compartments formed by the original diaphragm plates, the intermediate diaphragm plates, and the rotor shell.
