Abstract

A heat exchanger is especially for cooling cracked gases with boiling water. It consists of pipes (1) that the gas to be cooled flows through and that are surrounded by a cooling jacket with a coolant flowing through it. The end of each pipe that faces the gas intake is surrounded by a sleeve. The coolant flows through the sleeve. The volume of coolant flowing through the sleeve is less than the heat supplied from the gas being cooled. (FIG. 1).
