<p>Heat is conveyable to a fresh water duct via a heat-exchanger in the seal area. The system is used for recovering heat at a point in a waste water duct, pref. at an odour seal. The exchanger is in the form of a flow chamber (15) incorporated into the fresh water duct, bounded by walling, pref. the external walling (7) of the odour seal (1). It can consist of a tube (8) surrounding the odour seal at an interval (a) and sealing it in both sides, with an inflow connection (14) at one end (13) and deflecting connection (12) for fresh water at the other end (11).</p> |
