Abstract
A heat exchanger for transferring heat from a dust-containing gaseous medium to a second medium comprises a housing (3) with an inlet (1) and an outlet (5) for the gaseous medium, which flows along a U-shaped path around a partition wall (2) suspended from a top plate (4). The second medium flows along U-shaped pipes (6) in the U-shaped path from an inlet chamber (29) to an outlet chamber (28). Rapping cylinders (13), which are mounted on the top plate (4), periodically rap the pipes (6) to dislodge dust from the pipes into a discharge hopper (12). The top plate is mounted via resilient supports (31) on the upper edge of the housing (3).
