Abstract (en)
[origin: WO8605262A1] A heat exchanger (1), which is particularly intended for use in the exchange of heat between materials that are to be employed in a process for biogas production, and materials that have been employed in such a process, has two helical passages (2, 3) formed by two plate strips (4, 5), which are welded to a core (6) and a cylindrical casing (7), and which both have approximately the same angle of pitch theta . In order to avoid deposition and clogging, good flow conditions must be ensured. To obtain this, the inlet pipe stubs (8) and the outlet pipe stubs (9) of the heat exchanger are connected with the helical passages (2, 3) substantially without change of the cross-sectional area through the pipe stubs (8, 9) and the helical passages (2, 3).
