ABSTRACT:
Each of vertical frame members which constitute a frame body of a high-temperature denitration apparatus and which are erected in a spaced-apart relationship in a direction of exhaust gas flow is provided by a pillar member. The pillar member is an integral combination of a web with upstream and downstream flanges so as to improve thermal conductivity of the same. The web of the pillar member is formed with openings for suppression of thermal capacity to a minimum so as to reduce in weight the web and enhance a temperature rising velocity of the web.
