Bayonet tube heat exchanger.

摘要

A bayonet tube heat exchanger and the method of use of the heat exchanger, the exchanger having a bayonet tube [12] positioned within a sheath, [11] the bayonet tube being under a vacuum. The bayonet tube removes non-condensible gases from a vapor condensing within the sheath. An alternate embodiment uses a plastic baynonet tube as an inlet for fluids into an annular passage between the bayonet tube and its sheath. Multiple sheaths and bayonet tubes are disclosed.
