Heat exchanger, comprises pipes for transporting first medium through reservoir containing granular material and flow of second medium

摘要

A bundle of pipes (7) is used to transport a first medium through a reservoir (2) with an inlet (14) and outlet (15) for a second medium to flow through. The reservoir contains granular material. The granular material is in the form of a fluidised bed (16) supported by a distributor plate beneath the pipes.
