Title: Heat transfer by endothermic and exothermic chemical reaction - reactor and cooler pressure altered whilst temp. remains constant
Inventor: NOWAK RUDOLF DIPL ING
IPC: C09K5/16
Filed: 1975-02-25
Abstract: In the parent patent for the transfer of heat, materials are used which react chemically endothermically when the temperature is raised and exothermically when their temperature is lowered. As an example for the transfer of heat from a reactor to a cooler by means of a mixture of materials, the chemical equation Li ALF6 (1) + 2AL (c, l) = 3LiF (1) + 3 ALF (g) was gouted. When the temperature was raised to say 1100 degrees C, the highly endothermic formation of gaseous aluminium subfluoride resulted, whilst on cooling to say 600 degrees C the highly exothermic lack of proportion in the subchloride developed. In the patent of addtn, heat if fed into or withdrawn from the system by subjecting the material to pressure causing them to react endothermically or exothermically, whilst maintaining their temperature constant, or allowing it to fall or rise by a desired amount. The materials are fed through a heat radiating and a heat absorbing system in a closed circuit. Heat can be transferred from one system to another whilst maintaining the high temperature of the reactor of lowering it as required a little. The amount of heat transferred in kcal/kp heat transferring agent is remarkably high compared to conventional plant without high pressure.
