FRAME STRUCTURE OF HIGH TEMPERATURE NOx REMOVAL EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide a frame structure of high temperature NOx removal equipment designed to minimize thermal expansion difference and thermal contraction difference due to temperature difference caused among members of a catalyst packing frame during start and stop of operation and designed to reduce generation of thermal stress.

SOLUTION: Vertical frame members are erectly arranged with a predetermined space therebetween in flow direction of exhaust gas. Each frame member is a pillar member 3' formed by a flange 3a on the upstream side and a flange 3b on the downstream side which are integrally joined through a web 3c. The web 3c of the pillar member 3' is provided with holes 3d designed to minimize thermal capacity.
