. Supplement to Spons dictionary of engineering, civil, mechanical, military, and naval. ciently bituminous to coke in ordinary ovens, may, however, be coked in the Coppee oven; thecombustion of the gases evolved, by a double admission of air ; the combination of all the hot gasesin a common flue F, running beneath the whole range, and then- utilization for heating boilers, andthe employment of flues I for cooling and preserving the brickwork. The flames from O O pass 943. through a series of openings A, made at the springing of the arch, and circulate in channels B, thenpassing beneath the sole of the adjacent oven, enter by a vertical flue G into F, which first passesbeneath the boilers R, and then leads to the chimney C. The gases are burnt in the channels bytwo sets of jets of warm air, one entering the oven at D, and the other entering the vertical flues B;the admission of the air is regulated by slide bars H and F. Galleries I under the brickwork COKE OVENS. 425 are traversed by currents of cold air, which cool and preserve the structure. The air enters at K, andtraverses four ordinary brick galleries L; at the point M in the centre of the block of ovens itascends, entering the flues I in order to reach the chimneys N. To diminish the loss of heat byradiation, the tops of the ovens are covered with a bed of clay P, on which bricks are laid. Theordinary dimensions of an oven for a coking of twenty-four hours are—length, 30 ft.; width, 18 in.;heig
