Heat exchanger packer for regenerative heat exchangers with special cold-end configuration and integrated cold-end layer

摘要

The invention relates to a heat exchanger packet (7) for regenerative heat exchangers such as those used especially in large firing installations and waste gas cleaning installations. The aim of the invention is to solve the problem of the corrosion of the so-called cold end of the heat exchanger packet (7), especially to improve the construction of the heat exchanger packet in such a way as to solve this corrosion problem at the cold end and to integrate a corrosion-resistant cold-end layer (5) in the heat exchanger packet (7).
