The rate of heat exchange in a regenerative-chamber filled with four different checker works was investigated under actual conditions. It was found that the heighest rate of heat exchange per unit volume of checker works was in spherical shaped bricks while the lowest rate of that was in a solid chimney type. However there was no appreciable difference between these two above mentioned in respect to the rate of heat exchange per unit heating surface. In another word under present conditions the total heat exchange mainly depends on its heating surface although it is slightly affected by the velocity of gas. Having been thus obtained the coefficient of heat transfer, the most suitable heating surface for an unit calorific mass of gas was calculated out in order to give a basic data for the design of regenerators. As to the theory of regenerators, the author has also calculated graphycally the temperature distribution in respect to the time and space, whereby the conductivity of brick was taken in consideration.
