Abstract
The invention refers to a process and devices for the reutilization of low-level thermal energy. According to the invention, devices are utilized forming an evaporator-mixer, advantageously connected to devices forming an evaporator-separator in order to supply from a low-level heat source, for example at 25.degree. C., higher-level heat, for example at 80.degree. C., by making use of the phenomena of evaporation and mixing of two fluids in vapor-pressure equilibrium at different temperatures. The invention also allows and applies in particular to the utilization of the noble thermal energy consumed in a high-temperature boiler. To this end, the heat given off in the boiler is first used to assure in evaporator-separators the formation or reconstitution of concentrated solutions from diluted solutions, and these concentrated solutions are utilized according to the needs of demand to extract by means of evaporator-mixers heat coming from a low-level source.
