PLATE FIN AND COMBUSTOR USING THE PLATE FIN

摘要

20 This invention provides a plate fin which can attain low pollution combusti on without the loss of pressure. The plate fin includes an internal wall panel which forms an internal wall of a combustion chamber, an external wall panel facing the internal wall panel and forming a layer-form air flow passage between the internal wall panel and the external wall panel, and a plurality of cooling fins disposed in the layer- form air flow passage. The internal wall panel has a cooling air outlet, and the external wall panel has a plurality of cooling air inlets, both of which communicate with the layer- form air flow passage. Each of the cooling fins has heat transfer plates which are dispose d parallel to the direction of cooling air flow through the layer-form air flow passage an d connection plates which connect the heat transfer plates to each other.
