Patent CA-2276221-A1 (CA)
Inventor: MARSCH HANS-DIETER
IPC: B01J8/04
Filed: 1999-06-25
Abstract: With a device for performing catalytic chemical reactions of a fluid in the gas phase, besides avoiding the known disadvantages, a device with two catalyst beds of different life spans are supposed to be designed in such a way that the catalysts can be changed independent of one another, without taking into account unutilised dead spaces and with the possibility of being able to circumvent each bed.      This is achieved, in that a) the first catalyst bed (6) in the flow path has a lesser catalyst volume than the second catalyst bed (7); b) the first and second catalyst bed (6, 7) are designed largely cylindrical, whereby the cylindrical boundary wall (12) of the inner catalyst bed (6) forms the cylindrical inner wall of the second catalyst bed (7); and c) the first catalyst bed (6) can have a flow-through radially and the second catalyst bed (7) axially.

Patent CA-2278732-A1 (CA)
Inventor: TSUNODA TADASHI
IPC: F28F9/00
Filed: 1998-01-23
Abstract: An annular heat exchanger (2) provided with a high temperature fluid passage inlet (11) at one end in the axial direction and a low temperature fluid passage inlet (15) at the other end in the axial direction is supported inside a cylindrical outer casing (9) via a heat exchanger supporting ring (36). The heat exchanger supporting ring (36) connecting a low temperature section near the low temperature fluid passage inlet (15) of the heat exchanger (2) and a posterior flange (33) of the outer casing (9) is formed by bending a sheet in a cross-sectionally step shape so that it can readily undergo elastic deformation to offset the thermal expansion of the heat exchanger (2). This ensures positive sealing between the high temperature fluid passage inlet (11) and the low temperature fluid passage inlet (15) of the heat exchanger (2) while minimizing the thermal stress occurring in the heat exchanger (2) and the outer casing (9). The heat exchanger supporting ring (36) also has a function of partitioning between a combustion gas passage inlet (11) and an air passage inlet (15).
