HEAT EXCHANGE METHOD OF GASEOUS MEDIA Russian patent published in 2013 - IPC F28C3/12 

FIELD: power industry.

SUBSTANCE: heat exchange method of gaseous media, for example for hot gas and air, is proposed, by means of a regenerative heat exchanger with fluidised bed, which includes gas and air chambers with grids for parallel passage of heat exchanging media and in-series movement of intermediate disperse heat carrier. Grids are installed in inclined direction; axes of holes in them are directed towards the grids lifting. Filling pipes are perforated and located in cavities of chambers. The method consists in passage of hot gas flow through intermediate disperse heat carrier with further flow of the obtained heated fluidised bed of heat carrier from gas to air chambers. Then, gas flow is passed through the above air bed. Intermediate disperse flow of heat carrier at the gas chamber outlet is divided into two flows, each of which is then turned to opposite sides through 180° and directed along the gas chamber walls.

EFFECT: invention allows reducing heat losses at passage of the working process.
