installation for the recovery of heat from the exhaust gases of combustion plants

摘要

Heat exchanger having gas ducts (62), which are vertically arranged but cause a meandering through-flow of the combustion gas, and a distributing space (8), which adjoins the gas ducts above the heat exchanger and has a supply conduit (12) for the combustion gas, and a turning space (13), which adjoins the gas ducts below the heat exchanger and has a condensate outlet (14), and a covering (4), running all the way round, of the heat exchanger (6) made of a non-corrosive material, said covering forming on one side a discharge duct (A1) with chimney connection for the cooled combustion gas, a retention space (16) for influencing, via a louvred flap (18) arranged in the further combustion-gas path, the dwell time of the cooled combustion gas before entering the chimney.
