Smoke-consuming; fire-bridges.-Air for secondary combustion in a steam-generator furnace is supplied from a hollow chamber at the rear of the fire-bridge, the direction of delivery being approximately the same as the direction of travel of the furnace gases. The chamber is formed on one side by the bridge b, and on the other side by a vertical plate h and an inclined plate i, having grooved corrugations i<3>. The current of air passing into the flue through the opening i<2> is directed by suitably-shaped bars i<1>, k. The supply of air is regulated by a damper f. The bridge consists of a brickwork foundation e and a metal portion b, the rear face of which is inclined.
