Abstract (en)

[origin: US4901448A] The invention relates to a suspension heat exchanger for heat exchange between gas and fines. It contains a plurality of cyclone separators which lie one above another with their axes aligned vertically and in which the cover walls and the inlet pipe connections of the substantially straight upper parts of the cyclones are inclined at an acute angle with respect to the horizontal. This contributes to a particularly simple and space-saving overall construction and to a favourable material separation with relatively low pressure loss.
