Abstract: 852,498. Pulverulent fuel furnaces; liquid or gaseous fuel furnaces. COMBUSTION ENGINEERING Inc. Dec. 8, 1958 [Dec. 12, 1957; Dec. 17, 1957], No. 39450/58. Class 51 (1). [Also in Group XIII] A tubulous vapour generator is fired by at least three rows of tilting burners directing streams of fuel and air to converge on an axis transverse to the general direction of flow of the combustion gases in the chamber, or tangentially to an imaginary surface of revolution about that axis. In one embodiment, Fig. 1, two vertically spaced horizontal rows of pulverulent fuel burners 10 on each of the front and back walls of an upright tube lined steam generator are directed tangentially to an imaginary horizontal firing cylinder 75. In each row the burners 10 alternate with tiltable air inlet nozzles, and the direction of each burner of a row is separately adjustable. By adjusting all the burners of a row in the same manner, the burning gas mass may be moved within the furnace, or the diameter of the imaginary firing cylinder changed. By adjusting each burner of a row separately, the imaginary firing cylinder may be tilted, or alternate burners may be adjusted to give oppositely rotating gas streams. The direction of the individual burners in each row may be controlled by thermostats located in the individual elements of the superheater S1 so that the temperature of the gases leaving the furnace are maintained constant over the width of the furnace. In another embodiment, Fig. 22, two burners 95, 96 in the front wall of a low head horizontally arranged steam generator co-operate with a burner 97 in the roof and a burner 98 in the rear wall to form a gas mass rotating about a horizontal axis. Three burners only may be used, Fig. 23, not shown. In an upright steam generator, four rows of burners on each of the front and rear walls may be arranged so that the upper pair of burner rows on each wall are directed tangentially to an upper firing cylinder and the remaining burners deliver tangentially to a lower firing cylinder. The direction of rotation of the two gas masses formed may be same or opposite.

Filed: 1967-08-30
Abstract: 1,157,220. Rolling. VERWALTUNGSGESELLSCHAFT MOELLER U. NEUMANN OFFENE HANDELS-GESELLSCHAFT. 30 Aug., 1967 [14 Sept., 1966], No. 39636/67. Heading B3M. A tie-rod system for use in a prestressed rolling mill includes, disposed between the head 10a of a tie-rod 10 and the upper chock or housing cap 18 of the mill, an hydraulic cylinder 11, an annular piston 12, and a divided ring 16, 17. Between the ring 16, 17 and the piston are positioned two rings 20, 21 whose teeth 20a, 21a can either intermesh in tooth-togap contact or be placed in tooth-to-tooth contact, by rotation of the ring 20 using a cylinder 27. When in tooth-to-gap contact, the mill can be operated normally either with a constant prestressing force applied to the rod 10, or with the force in the working chamber 15 varied according to a regulating signal. When the pressure is released in the chamber, springs 13 urge the piston downwardly to allow the ring halves 16, 17 to be removed and hence the cap or chock 18 to be lifted clear of the tie-rod. When in tooth-to-tooth contact, the prestressing force of the mill passes through the teeth and not the chamber 15, the roll gap then being adjusted by a screw mechanism, Fig. 5. The mechanism includes an externally threaded and internally splined sleeve 46 which extends between a lower housing part 1 and a fixed nut 45 in an upper chock 18. Rotation of the sleeve, by means of gearing 48-53, varies the roll gap. In order not simultaneously to vary the prestressing force, the tie-rod 10 is arranged to be rotated by an integral toothed member 54, the lower threaded end of the rod moving relative to a fixed nut 55. The nut can, however, be rotated by a worm 56 if the tie rod is to be axially adjusted.
