Abstract
A system for the recovery of heat from waste gases includes a plurality of conduits 3 for waste gas discharged from one or more thermal sources of such gas (e.g. a thermal treatment furnace 1), a plurality of heat exchangers 4 each being connected to one of the waste-gas conduits and to a circuit (e.g. conduits 8) for a working liquid, which is thereby heated by the waste gas to produce e.g. hot water, superheated water, or steam. The liquid flow may traverse the plurality of the heat exchangers 4 in parallel (e.g. Fig. 1) or in series (e.g. Fig. 2) or parallel flows of the liquid may each flow in series through a group of the heat exchangers (e.g. Fig. 3). The liquid circuit may include a vapourizer (e.g. 14 Figs. 4 to 7) delivering steam to a turbine or to a heat exchanger in which water is superheated. Where the working liquid is a diathermic liquid, other than water, it may pass through a heat exchanger in the vapourizer 14 to vapourize the water therein and produce said steam.
