Abstract

A radiation cooling unit for cooling dust-laden gas. At least one cylindrical radiation heat transfer surface is disposed in a tank adjacent to, and extending essentially along the length of, an inner wall of the tank. First knock-or impact-beating devices disposed externally of the tank act upon the cylindrical heat transfer surface through the wall of the tank. A plurality of essentially radially and axially extending, partition-like radiation heat transfer surfaces are disposed within a free space in the tank, and each comprise axially extending tubes and at least one header. Second knock- or impact-beating devices are disposed externally of the tank, extend through the cylindrical heat transfer surface, and act upon radially outwardly disposed edges of the partition-like heat transfer surfaces, with the length-to-width ratio of the latter being such that they are adapted to be accelerated and cleaned by the second knock- or impact-beating devices. The partition-like radiation heat transfer surfaces are preferably radially distributed about the periphery of the cooling unit.
