ABSTRACT:
In batteries of tubes conducting a heating fluid air is led through the spaces between the tubes, to be heated for use in grain drying installations or the like. Airborne dust and impurities form deposits on the tubes and impair heat transmission. The deposits are removed from the tubes by increasing at intervals the air velocity by means of a grid structure defining passages having a reduced flow area and placed in front of the interspaces between the tubes.
