A method of heat exchange comprising flowing liquid heat-exchanging media upwardly as a stream containing fluidized particles onto some of which material is precipitated from the liquid thereby enlarging the particles, temporarily increasing the flow rate of the stream to fluidize the thus enlarged particles, expanding the stream to decrease the flow rate and permit settling out of a coarse fraction of particles and returning the stream to its original flow rate to readmit particles into the non-expanded stream. |
