During the past year, Carbofrax and Diamel brick, each having distinctly different but superior, heat‐transfer properties as compared with fire brick, were tried out as part of the regular checker brick in a full‐sized standard single‐shell oil‐gas generator, which was operated under normal conditions. It was hoped that increased gas‐generating capacity would be obtained by their use, but such was not the case, chiefly because of the influence of other factors having as much bearing on generator capacity as the checker brick. The chief limiting factors were (1) the remoteness of a large portion of the checker brick from the combustion chamber and therefore from the source of heat supply; (2) uneven heat distribution in the generator; and (3) the formation of heavy cokelike carbon deposits on a portion of the checker brick. With the development of improvements in the generators and the correction of some of these difficulties, there appear to be excellent possibilities in the use of brick of superior heat‐transfer properties in promoting operating efficiencies and in increasing gas production.
