Abstract
A heat exchanger for cooling process gases which are under high pressure and temperature. The withdrawn heat is used for high pressure steam generation in accordance with the natural circulation principle. The heat exchanger comprises U tubes suspendedly inserted in a plate or tube sheet. Two chambers are provided above the plate, are separated from one another, and are intended for the coolant-steam circulation. A housing surrounds the U tube bundle and is connected to and below the chambers. The housing has at least one process gas inlet and at least one process gas outlet. One arm of each U tube is constructed as a double tube. The inner tube has the function of a gravity tube, and the remaining annular conduit, as well as the remainder of each U tube, have the function of risers.
