360,956. Coke ovens. POLLAK, J. E., 20, Holborn, London.-(Hinselmann Koksofenbauges ; 30, Zwiegertstrasse, Essen, Germany.) Aug. 11, 1930, No. 24063. [Classes 51 (i) and 51 (ii).] Regenerators.-In a coke oven having transverse regenerators, alternate regenerators f<2>, which are of an auxiliary nature are formed within hollow walls separating the main regenerators f, these walls being built up of stretcher bricks a<1>, Fig 5, and header bricks a<2>, the latter extending across the space within the wall and forming vertical partitions dividing it into a number of compartments. Pairs of con nected upflow and downflow flues h alternate along the length of the heating-wall, and each pair is connected to one of the compartments of the regenerator f<2>, so that inflow and outflow compartments alternate along the length of the regenerator, and to one or other of the two adjacent main regenerators f. When operating with rich gas supplied through conduits e air is supplied to all the inflow regenerators through base passages n<1>, n<2> beneath the main regenerators, and one of the two passages n beneath the auxiliary regenerators, the other serving for outflow of the waste gases. The connections are preferably such that upflow flues on one side of an oven correspond in position with downflow flues on the other side. Lean gas, when used, is preheated in the regenerators f<2>. The passages n<1> n<2> beneath the main regenerators are connected respectively to one half of the length of the corresponding regenerator through parts o<1>, o<2> and passages m, and each of the ports o<1>, o<2> is controlled by a damper block l having a coned projection fitting in a correspondingly formed seating in the brickwork, and forming a pivot about which the block can be turned. The blocks can be adjusted through openings r, p. Similar blocks are used for controlling the supply of air or gas to the regenerators f<2>. The end portions of the main regenerators corresponding with one or a small 'number of heating-flues are divided off from the remainder by partitions g, and a larger quantity of gas is supplied to the end flues to compensate for the increased cooling at the ends of the ovens. As shown in Fig. 5 the walls partitioning the regenerators f<2> are of two brick thickness, and each brick is jointed to a brick a<3> in the side wall having a portion s<2> projecting into the regenerator space. The rich gas passages e are formed in the cross bricks a<2>, and the minimize leakage, plates p<1>, p2, which break joint with the bricks, are fitted as shown. The heating-walls are built up of stretcher and header bricks which fit together with zig-zag joints.
