A heat store component for passage of a gas flow, in particular, in heat exchangers of flue gas cleaning systems, is provided, including: a mounting forming an inlet and an outlet side of the heat store component for the gas flow fed therethrough; and a first and a second heat storage medium arranged one behind the other in the gas flow direction and each including a plurality of substantially parallel flow channels. The second heat storage medium is formed from one or more honeycomb blocks, which include a body made in one-piece manner of a plastics material and incorporating a plurality of parallel flow channels separated by channel walls, wherein the plastics material includes a plastic containing virgin polytetrafluoroethylene (PTFE) as a fraction of ca. 80% by weight or more and optionally a high performance polymer differing from the PTFE as a fraction of ca. 20% by weight or less.

A gas to gas heat exchanger 110 is equipped with a heat transfer element cleaning system 160, effluent collector hopper 162 and effluent collector hopper cleaning system 164. The heat transfer element cleaning system 160 is useful to remove accumulated substances from the heat exchanger 110 heat transfer elements 134. The effluent collector hopper 162 is useful to capture a cleaning fluid used to remove accumulated substances from the heat exchanger 110 heat transfer elements 134. The effluent collector hopper cleaning system 164 is useful to remove accumulated substances captured with the cleaning fluid from the effluent collector hopper 162 to prevent clogging thereof.
