This citation summarizes a one-page announcement of technology available for utilization. a new kind of heat exchanger for recovering energy from flue gases is more effective than either tubular recuperators or rotary regenerators. The exchanger, a plate/fin recuperator, is compact and has packaging flexibility unavailable in other models. The unit has utilized hot flue gas to preheat combustion air with 91-percent efficiency. The exchanger is made by stacking layers of corrugated stainless-steel sheet separated by stainless-steel plates. The corrugations in alternate layers are at right angles so that flue gas cna flow vertically while the combustion air flows horizontally between plates heated by the hot gas.
