REGENERATIVE HEAT EXCHANGER WITH FLUIDISED BED

摘要

FIELD: power industry. ^ SUBSTANCE: regenerative heat exchanger with fluidised bed includes gas and air chambers with grids for parallel passage of heat exchanging media and in-series movement of disperse intermediate heat carrier. Grids are installed in inclined direction; axes of holes in them are directed towards the lifting of grids. Filling pipes are perforated and located in cavities of chambers. Internal surface at least of one grid is provided with longitudinal ribs; at that, height of rib is approximately equal to thickness of fluidised bed of disperse intermediate heat carrier. Channels connected to gas chamber cavity are made along outer perimetre of air chamber. ^ EFFECT: improving operating efficiency of heat exchanger by reducing heat losses during the working process. ^ 3 dwg
