A catalytic reactor/heat exchange device () is provided for generating a catalytic reaction in a reaction fluid flow () and transferring heat to a cooling fluid flow (). The device includes reaction flow channels () with turbulators () therein. The turbulators () include an initial portion () and a selected portion () that includes a catalytic layer or coating () to initiate the desired catalytic reaction at a location () located downstream from the initial portion (). In some preferred forms, each of the selected portions () of the turbulators () include at least one downstream section () wherein the heat transfer performance has been intentionally reduced to improve performance of the device () during start up conditions.

Catalytic reactor/heat exchanger

Venting difficulties in a heat battery including a first container (10) for housing a heat storage salt that may be in the solid phase or in the liquid phase, a heat exchanger (22) within the container (10) and a second container (12) surrounding the first container (10) in generally spaced relation to provide an insulating space (14) about the first container (10) along with coolant inlet and outlet connections (40, 42) to the heat exchanger (22) are avoided in a vent system (52) including a vent inlet (66) generally centrally located in the top wall (56) of the first container (10) generally centrally of the ends thereof. A vent passage includes a check valve (106) located in close proximity to the vent opening (66) and the vent opening is surrounded by a cup shaped baffle (60) having an opening (62) facing the interior of the container (10). A filter (78) is located between the check valve (106) and the opening (62) to the baffle (60). The check valve (106) is located in a valve housing (104) which itself serves as a safety valve to vent pressure in the event the check valve (106) malfunctions.
