Honeycomb block and heat exchanger elements produced therefrom, in particular for flue gas cleaning systems of power plants

摘要

The invention relates to a honeycomb block, in particular for producing heat exchanger elements for flue gas cleaning systems of power plants. The honeycomb block comprises a body that is integrally produced from a plastic material and comprises a plurality of parallel flow channels which are separated from one another by channel walls. The aim of the invention is to improve the mechanical properties and thus the practical suitability. This is achieved in that the plastic material comprises a plastic which contains a content of approximately 80 wt.% or more of virgin polytetrafluoroethylene (PTFE) and optionally a content of approximately 20 wt.% or less of a heavy-duty polymer which is different from the PTFE.
