Effective Heat Exchange in the Lower Zones of Regenerators

JSGT 1933 V17 T102-T117

The paper demonstrates a method for improving heat exchange in regenerators by increasing the effectiveness of the heat exchange in the lower zones of regenerators. The design of the filler bricks is such that the regenerator is divided into three zones, the lower of which have successively increased restriction to the path of the gases and maintains the velocities of the gases by compensating for their reduced volume at the lower temperatures. Turbulence is also provided in these lower zones to improve the effectiveness of the heat exchange. The bricks required are of a comparatively simple design, and a special feature of it is that, although the velocities are maintained in the lower zones of the regenerator, it is so arranged that the gases do not pass through the regenerator any more quickly than would be the case when passing through straight-walled vertical passages of the same height with reduced velocities in the lower zones
