    摘要： In the production of carbon black from a hydrocarbon oil which is injected axially as an atomized liquid or vapour into a cylindrical furnace co-currently with a longitudinal stream of a burning fuel gas, an axial oil supply pipe and a surrounding fuel gas supply pipe are axially movable with respect to a central inlet in a metal plate constituting the inlet to the furnace. As shown, a stream of air passes from a radial supply pipe 9 through an outer annular space in a cylindrical air box 8 into an inner annular space bounded by an air baffle 10 and thence into a furnace 5 through apertures in a plate 12. About two-thirds of the air passes through a central aperture 14 and the remainder passes through two series of apertures 18 and 16 (Fig. 2). Fuel for combustion passes through a pipe 20 surrounding an axial oil injection pipe 30 and terminates in a flame deflector disc 24 having a tubular extension 26 covering a circular series of fuel gas outlets 28 (Fig. 3). The fuel gas-oil injection assembly passes through a packing gland 46 carried by air box 8 to enable it to be moved axially. The assembly may be moved so that the flame deflector disc and tubular extension are inside the furnace (Fig. 4, not shown).
