FIELD: heat-exchange apparatus.
SUBSTANCE: device comprises housing provided with means for fluidizing the bed of material to be fluidized in the zone of pseudo-fluidizing located inside the housing and heat exchange pipes arranged in the zone of pseudo-fluidizing for drawing heat from the zone and /or supplying heat to the zone. The heat exchange pipes pass in the longitudinal direction along the axis of the zone of pseudo-fluidizing and are located in the cross-section of the housing at the corners of the rectangular whose side length exceeds the length of the other side at least by a factor of 1.5. The method comprises generating pseudo-fluidized bed from the material to be fluidized and drawing/supplying heat with the use of heat-exchanging pipe.
EFFECT: enhanced efficiency.
