Abstract:
1. A frame structure for a high-temperature denitration apparatus, said frame structure comprising: a box-shaped casing with front and rear open ends for passage of hot exhaust gas and a frame body within said casing, said frame body comprising a plurality of vertical frame members erected in a spaced-apart relationship widthwise and in a direction of exhaust gas flow of said casing, and a plurality of horizontal frame members fixed to said vertical frame members into a latticework, thereby providing spaces to be filled with catalysts in a plurality of widthwise rows and in a plurality of vertical stages within the casing, each of said vertical frame members in the direction of exhaust gas flow being provided by a pillar member which is an integral combination of a web with upstream and downstream flanges, said web being formed with openings for minimization of thermal capacity.
