摘要
A heat exchanger panel having vertical tubes (1, 2) which form loops between an inlet (1A) and an outlet (1B) via which they are suspended from a rigid structure (3, 4), and intended to come into contact via their outer surfaces with a soot-laden gas characterized in that its tubes are separated from one another at a pitch which is a little greater than their diameter, in that the tubes of the central portion are interconnected by fins, and in that the end tubes directly connected to the suspension structure are fixed to one another and to the nearest adjacent tube by short members (14, 15) welded on either side to adjacent tubes (21, 22, 23) at a level below that of the top loops of the panel, and are connected to one another and to the adjacent tube below the fixing members by fins (26).
