Abstract

Regenerative heat exchanger consists of a thermally insulated pressure vessel with a liq. inlet at the bottom and a branch for the vapour of this liq. near the top. It contains a packing of high thermal capacity consisting of closely packed ceramic material to give thermal storage. It has a liq. level controller by means of which the liq. level in the vessel can be adjusted and controlled. This has a sensor for the level which falls when energy is being absorbed by the packing and rises when it is being released. The packing is spheriodial in form. It can contain an inorganic salt (e.g. BiCl3, SnCl2, ZnCl2, etc.) or a salt eutectic (e.g. 50/50 NaCl/BeCl2). Used in processes where heat is generated intermittently and where an effective and economical storage is desirable.
