Abstract

1340146 Carbon black CONTINENTAL CARBON CO 23 Sept 1971 [11 March 1971] 44528/71 Addition to 1282518 Heading C1A In a carbon black furnace according to the parent Specification, which is characterized inter alia by possessing a burner assembly for producing an axial stream of combustion gases by introducing through it a suitable fuel to mingle with an oxygen containing gas stream, which burner assembly is spaced from tangential parts, positioned downstream of the burner assembly and being adapted to admit a second stream of combustion gases tangentially into the axially flowing stream, the, or each, tangential port is located a distance from the point of fuel ingress of six to fourteen times the diameter of the refractory lining of that cylindrical portion of the reactor through which the tangential ports pass. During the process of production 3500 to 5200 BTU preferably 3600 to 4500 BTU of heat per pound of feedstock is introduced through the primary combustion gas stream and 1000 to 2500 BTU preferably 1200-2000 BTU of heat per 1b of feedstock is introduced through the secondary combustion gas stream. The air to fuel ratio for the primary stream may be from 10 : 1 to 15 : 1 by volume and the air to fuel ratio for the secondary stream may be from 10 : 1 to 20 : 1.
