ABSTRACT:
A process for indirect heat-exchange between a solids-containing gas and the inner wall of a heat-exchanger through which the solids-containing gas to be cooled or heated flows, comprising introducing a flushing medium separately from the solids-containing gas into the heat exchanger, the flushing medium being directed angularly at the wall and sweeping about said wall whereby said wall is kept substantially free from solid deposits. Advantageously the heat exchanger is circular in cross-section, the gas/solids mixture is introduced tangentially, and the flushing medium is discharged toward said inner wall through openings in an arm which rotates within the heat exchanger, means being provided to remove gases and solids from the heat exchanger.
