SEALING ARRANGEMENT OF AIR COOLER FOR VERTICAL TUBE GENERATOR IN THERMAL POWER PLANT

摘要

The invention relates to an improved sealing device for vertical type generator air coolers adaptable to thermal power plant, the device comprising: a tube sheet (6) provided on the gasket sealing surface of a water box flange (1), the water box flange (1) resting on the generator duct (2), a gasket (4) disposed on the sealing surface; at least one water box (5) connected to the water box flange (1) being disposed downwardly, the tube sheet (6) is provided with step-like configuration at both ends such that the gasket sealing surface and the water box flange (1) remain disposed outside of the generator duct (2) to prevent entry of leaking water into the generator windings.
