Abstract (en)
[origin: US4706742A] Raw gas/purified gas heat exchanger, particularly for dust-laden raw gas, features heat exchanger tubes through which purified gas flows and are arranged in a substantially vertical channel which is open at the bottom and is acted upon by raw gas from above. The tubes are arranged in different two-dimensional planes extending parallel to each other and to the symmetry axis of the channel.
