A suspension system is presented for a distribution chute of a device for uniformly spreading powdery materials over a circular surface. The distribution chute is suspended in a pivoting manner from a cage in such a way that the angle of tilt of the chute in relation to the vertical axis is adjustable. This cage is suspended from a peripheral annular ring having a vertical axis. The ring is vertically supported and laterally guided by wheels circumferentially spaced apart by an angle of 120.degree.. These wheels are mounted via bearings on a frame supporting the cage. An endless chain engages in a peripheral annular sprocket integrally connected to the cage in order to transmit to the latter a rotary motion about its vertical axis. A variant embodiment is presented with six smooth wheels, three of which have horizontal axes and three of which have vertical axes.

Device for uniformly spreading powdery materials

The probe comprises a probe arm provided with a series of orifices for simultaneously taking gas samples and measuring the heat at different locations of the charging surface and penetrating through an opening in the furnace. This opening is surrounded by a support hoop integrally connected to the wall of the furnace and provided with two diametrically opposite outer journals on which are articulated two parallel arms supporting between them the probe arm. This arm can move about the center of the said hoop under the action of at least one actuator mounted between the said hoop and the outer end of the probe arm, the arm comprising a circular sliding surface moving, sealingly, over the inner surface of the said hoop.

Probe for taking gas samples and heat measurements above the charging

The probe comprises a support in the form of a sheath, a series of internal pipes, retained by spacers and connecting orifices distributed along the sheath to a device for measuring and for receiving the gas samples outside the furnace, and thermocouples arranged at the level of the said orifices. In order to enable the pipes to be replaced without disassembly of the probe, the said orifices are situated in steps provided in the sheath, while the internal pipes, for taking gas samples and heat measurements are all individual, straight and exchangeable elements housed in straight support and protection channels, each traversing the sheath from the outside as far as the respective step.

The device comprises an inclined rotating chute with adjustable angle of inclination, having an elongated flat sliding surface with a rectilinear longitudinal side provided with a retaining edge, the opposite longitudinal side being the pouring side and having overall the shape of an elongated 'S' extending, without interruption and without corners, along the bottom end of the sliding surface as far as the bottom end of the rectilinear side.

Device and method for uniformly distributing materials on a circular

A pneumatic mixture which has a relatively high content of pulverulent materials in the propulsion air is formed in a single metering means. This mixture is propelled through a common primary pipe to a distribution head in which the mixture is divided into secondary currents which are delivered respectively to each of the injection points. A supercritical speed is imparted to the mixture in the distribution head.
