Abstract:
1. A heat exchanger for analyzing samples, the heat exchanger comprising: a. an outer wall of the heat exchanger, the outer wall forming a coil; b. an inner tube for containing cooling water, the inner tube forming a coil that is circumscribed by the outer wall and that has a cooling water inlet and cooling water outlet so that the inner tube is in fluid communication with a cooling water system; c. an annulus for containing steam so that heat exchange occurs between the cooling water and the steam so that condensate is formed in the annulus; the annulus being located between an outer surface of the inner tube and an inner surface of the outer wall of the heat exchanger, the annulus having a steam inlet and steam outlet so that the annulus is in fluid communication with the steam system; and d. an external shield attached to the heat exchanger to prevent contact with the steam contained within the annulus of the heat exchanger and to allow air to provide additional cooling between the outer wall of the heat exchanger and the external shield.
