摘要： A heat exchanger for a regenerative thermal oxidiser is described. The heat exchanger has a heat exchange bed that is disposed within a housing. The heat exchange bed is disposed parallel to the longest axis of the housing. A cavity is formed at either side of the heat exchange bed. Channels in the heat exchange bed link the two cavities. Because the heat exchange bed is disposed parallel to the longest axis of the housing, the area of the heat exchange bed facing the cavities is maximised, and the length of the channels is minimised, this reduces the pressure required to drive gas through the heat exchanger.
