GAS SEAL STRUCTURE OF HIGH TEMPERATURE DENITRIFICATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a gas seal structure of a high temperature denitrification apparatus which can minimize heat conduction through a seal guide and prevent the occurrence of hot spots in a casing.

SOLUTION: A seal plate 30 for preventing a short path of exhaust gas is fitted to the peripheral part of a catalyst packing frame 2 to protrude to the inner surface of the casing 1, and the seal guide 31 engaged with the seal plate 30 is fitted to the inner surface of the casing 1 through a heat insulation table 50 so that the seal plate 30 can slide freely when the frame is heat-expanded.
