Abstract (en)
[origin: EP2295736A2] An apparatus for converting the waste heat from a production process into electrical energy, whereby the production process comprises a number of sub-processes, in which the waste heat from at least two sub-processes is simultaneously extracted from the production process by a single closed work-producing cooling circuit (1), and in which there is at least one heat exchanger (3,4) for each sub-process in the form of an evaporator, with a primary section incorporated into the closed cooling circuit (1) and a secondary section through which a fluid is taken from the sub-process concerned to evaporate the coolant in the closed cooling circuit (1), whereby at least one of the aforementioned heat exchangers (3,4) has its secondary section incorporated into a cooling circuit of a sub-process that uses the same coolant, and such that after cooling in the heat exchanger concerned the coolant is mixed with the coolant in the closed cooling circuit by means of a mixer (11) followed by a closed mixing vessel (12) in which the fluid and gas phases of the coolant are separated, and there is a closed mixing vessel (12) in the closed cooling circuit (1) after the mixer (11) in which the liquid and gas phases of the coolant are separated, and coolant is tapped off from this for use in the aforementioned cooling circuit of the sub-process.
