Thermal regenerators are usually of massive dimensions or of the rotary type which though relatively small suffers from sealing problems. Small fixed bed regenerators cannot be used because they require frequent reversals from heating to cooling and vice versa and they are out of service during reversal. In the invention a sufficiently large number of fixed bed thermal regenerators 10 to 29 are used to allow some to be reversed while others supply the load. In this way reversal time becomes unimportant and the surface area to volume ratios of the packing material can be reduced so allowing small size regenerators to be used for a relatively large thermal load. |
