摘要： Control over the direction and inclination of a charge distribution chute within a blast furnace is accomplished with a compact and reliable drive mechanism. The drive mechanism includes a rigid control rod for varying chute inclination angle and a gear drive which translates angular position commands in the form of rotation about a vertical axis to reciprocation of the control rod. The control rod and its gear drive rotate with the chute while simultaneously varying the inclination angle.

摘要： A pulverized solid fuel is injected into a shaft furnace by being entrained in a stream of pressurized air, the resulting fuel-air mixture subsequently being further mixed with heated air being delivered to the furnace via a tuyere. The air used to entrain the pulverized fuel is diverted from the cold air supply to a mixing station, which is used to control the temperature of the hot air supplied to the furnace via the tuyere, and this diverted air is pressurized prior to the pulverized material entrainment.

摘要： An isolation and flow control valve in a furnace charging installation, installed in a discharge conduit of a storage hopper which may be alternately at ambient pressure for loading and furnace pressure for discharging, is characterized by a valve member which is caused to move serially in two directions during opening and closing. The movement is produced by an actuator mechanism including a pivot arm and a cam system and results in movement axially with respect to the conduit for seating and unseating and generally transverse to the conduit axis for controlling material flow through the conduit.
