Abstract
A heat exchange apparatus is composed of a plurality of tube banks arranged in rows each comprising a plurality of tubes arranged in a direction normal to a gas flow in a gas passage duct and in the heat exchanger, an interval of a space between mutually adjoining tube banks in the gas flow direction is less than eight times of a depth of a tube group disposed on an upstream side with respect to the gas flow and baffle plates are disposed in the respective tube banks for preventing a multibank tubing compound resonance. Each of the baffle plates disposed in an upstream side tube bank has an extension extending from a center of a most downstream side tube in the upstream side tube bank and having a length more than two times of a tube pitch in the gas flow direction, and each of the baffle plates disposed in a downstream side tube bank has an extension extending from a center of a most upstream side tube in the downstream side tube bank and having a length more than two times of a tube pitch in the gas flow direction.
