Abstract
An absorption waste-heat recovery system includes a high temperature generator for directly receiving a heat medium fluid containing waste heat for recovering heat therefrom and concentrating a solution having an absorbent dissolved therein and generating steam, a low temperature generator for re-concentrating the concentrated solution after reduction of its temperature by heat recovering means in the system by using the steam from the high temperature generator as heat source, an auxiliary generator for introducing the heat medium fluid after its heat recovery at the high temperature generator and again recovering heat therefrom, a condenser capable of condensing steam from the auxiliary generator and steam after the re-concentration of the concentrated solution at the low temperature generator, an evaporator for evaporating the condensed water condensed at the condenser, and an absorber for receiving the concentrated solution from the low temperature generator and the concentrated solution from the auxiliary generator and diluting these solutions by causing them to absorb the steam from the evaporator. A double-effect cycle using the high temperature generator and the low temperature generator and a single-effect cycle using the auxiliary generator share at least the evaporator and the absorber out of the condenser, the evaporator and the absorber.
