Apparatus for thermally cleaning an exhaust fluid stream

Abstract

An apparatus for thermally cleaning exhaust air containing combustible components comprises at least one combustion chamber for thermally cleaning an exhaust fluid stream and at least two containers adapted for gases to flow therethrough and containing heat storage material for heating the exhaust fluid stream to be cleaned before it enters the combustion chamber and for receiving heat from the cleaned exhaust fluid stream exiting the combustion chamber. Each of the containers has at least one first opening for connecting the container interior to the combustion chamber and at least one second opening for supplying exhaust fluid stream to be cleaned to the container interior and for withdrawing the cleaned exhaust fluid stream from the container interior. The containers accommodating the heat storage substances can be flexibly configured and, if desired, arranged one behind the other in a row. The supplying of the exhaust fluid stream to the containers and the withdrawal of the cleaned exhaust fluid stream from the containers are controlled by two slide valves associated each container, the valve slides of each of these slide valves being synchronously displaceable preferably by a drive which is common to each of the valve slides.
