Abstract
In apparatus for flow of a liquid medium e.g. a heat exchanger the liquid flows through a plurality of parallel vertical pipes 10 from a bottom chamber 4 to a top chamber 5. The apparatus contains a mass of particles which are fluidized in the pipes by the flow of liquid. In order to allow a higher speed of liquid flow, giving the apparatus greater capacity transfer means 11,12,13,14 are provided to convey the particles batchwise from the top chamber to the bottom chamber. This transfer corrects the tendency of the higher flow speed to carry the particles into the top chamber. Suitably the transfer means is a lock chamber 11 with linked inlet and outlet valves 12,13.
