Abstract
150,762. Anderson, R. J. April 4, 1919. Shaft furnaces; rotary furnaces; metallurgical furnaces; chemical manufactures, furnaces for.- Consists of a furnace or kiln adapted for the reduction of ores, for conversion of chemical compounds. manufacture of cement, and like operations. Fig. 1 shows the application to an iron or lead smelting blast furnace. Products of complete combustion from combustion chambers 41, 42, and products of incomplete combustion (including carbon monoxide) from combustion chambers 45, 46 are delivered into the charge, and in each combustion chamber the air and fuel are supplied in numerous crossing jets and in regulable proportions so that complete interaction coupled with precise regulation is obtained. Either gaseous, oil, or pulverulent fuel can beused. The cross-jetting is obtained as shown in connexion with the " primary " combustion chambers 41, 42, and diagrammatically in Fig. 5, by means of refractory air pipes 15 extending across the chamber and perforated all round, and by fuel jets 22 directed longitudinally of the chamber, and thorough mixture is further ensured by the staggered relation of the air pipes and of the fuel jets, as shown in Fig. 5, and by the fact that both air and fuel jets are in planes substantially at right-angles to the outlet from the chambers. Fig. 7 shows the application to a rotary furnace for conversion of heavy chemicals, and more particularly designed for the manufacture of sodium sulphide from sodium sulphate. Gases issuing at 92 at an upper level from the " primary " combustion chamber serve mainly to heat and soften the oncoming charge while gases of incomplete combustion issuing at 93 from the " secondary " combustion chamber at a lower level effect the desired reduction to sodium sulphide. The completed product is discharged at 91.
