Abstract
A heat exchanger for cooling hot reaction gas with a coolant. The exchanger rests on a gas-supply chamber (4) and has gas pipes (8). The pipes extend individually out of a wall (1) that surrounds the pipes and are accommodated in a pipe-slab floor (6) between the wall and the chamber. The pipes extend through bores (20) in the floor leaving an annular gap (21). At least one coolant-supply line (9) terminates on the side of the floor facing away from where the gas enters. Chambers (12) demarcated by a flat bottom (15), by a partition (13) that parallels the pipes, and by part of a wall-mounted ring (14) are accommodated in the half of the floor facing the side where the gas enters. The chambers communicate with a common coolant supply. One or more gas pipes (8) extends through every such chamber. The ring is positioned at the edge of the floor and surrounds all the chambers. The floor comprises a thinner section (18) that is cooled by the coolant and constituted by the bottoms of all the chambers and a thicker and rigid section (19) that the thinner section rests on by way of the partitions.
