Abstract

297,385. Hickton, R., Bagguley, W. W., Birks, G., and Hickton, R. G. March 18, 1927. Furnace bricks.-In a furnace for heating steam-generators, retorts, coke ovens, and the like, air for combustion is preheated in cavities in the furnace walls which are built up of bricks or blocks so shaped and arranged that no straightthrough joints exist for the leakage of flames or hot gases. The walls are preferably built of bricks as described in Specification 296,033, Fig. 10 showing part of a wall constructed of alternate courses of bricks a', a<9> of the form shown in Figs. 15 and 13 respectively. The cavities are produced by the use of outer facing or connecting bricks and all the bricks are formed with vertical holes v jointed at suitables places by semi-cylindrical depressions s to produce a honeycomb structure.
