Abstract: The disclosure relates to a multi-pass removable plate heat exchanger without a need of arranging interfaces or connections on a mobile pressure plate, and a specific heat transfer plate therefor. The heat transfer plate has a plurality of lateral regions, where a plurality of mutually communicative lateral-pass partitions or mutually isolated pass partitions are formed with specially shaped gaskets. With such kind of heat transfer plates, a multi-pass removable plate heat exchanger without a need of arranging interfaces or nozzles on the mobile pressure plate may be constructed. The disclosure further relates to a specially shaped gasket to allow construction of a multi-pass removable plate heat exchanger without a need of arranging interfaces or nozzles on the mobile pressure plate.

Abstract: A heat exchanger, for heating or cooling bulk solids, includes a housing including an inlet for receiving the bulk solids, an outlet for discharging the bulk solids, and a heat exchange chamber disposed between the inlet and the outlet. The heat exchanger also includes spaced apart heat transfer tubes supported within the housing, between the inlet and the outlet, and extending through the heat exchange chamber, for indirect heat exchange of a heat exchange medium in the heat exchange chamber with the bulk solids that flow, by gravity, from the inlet, and through the heat transfer tubes, toward the outlet. The heat transfer tubes include a first end for receiving the bulk solids, and a second end for release of bulk solids. At least one of the first end and the second end is moveable relative to the housing to accommodate thermal expansion or contraction.

Abstract: A heat exchanger includes a housing that includes an inlet for receiving bulk solids and an outlet for discharging the bulk solids. A first heat transfer plate bank is disposed between the inlet and the outlet. The first heat transfer plate bank includes a plurality of horizontally spaced apart, substantially parallel heat transfer plates for cooling the bulk solids that flow from the inlet, through spaces between adjacent plates. A second heat transfer plate bank is disposed between the first bank and the outlet. The second bank includes plurality of horizontally spaced apart, substantially parallel heat transfer plates for cooling or heating the bulk solids that flow from the spaces between adjacent plates of the first bank, through spaces between adjacent plates of the second bank, to the outlet. The plates of the second bank are horizontally offset from the plates of the first bank such that the plates of the second bank are not in vertically aligned with the plates of the first bank.

Abstract: A heat exchanger includes a housing including an inlet for receiving bulk solids, and an outlet for discharging the bulk solids. A plurality of spaced apart, substantially parallel heat transfer plate assemblies are disposed in the housing between the inlet and the outlet for cooling the bulk solids that flow from the inlet, between adjacent heat transfer plate assemblies, to the outlet. Ones of the plurality of heat transfer plate assemblies including a heat transfer plate and a pipe extending along a top end of the heat transfer plate to protect the heat transfer plate.
