Liquid metering and distribution arrangement for rotary reactor

Abstract

Flow control valves are mounted with corresponding axial rows of nozzles about the periphery of a rotary kiln. A metering cylinder is mounted on the kiln and rotates therewith. A piston member is moveable in the metering cylinder in alternately opposite directions to deliver a predetermined measured volume of a liquid hydrocarbon such as fuel oil from said cylinder equally in each direction of movement of said piston member. A first hydraulic circuit interconnects each of said liquid flow control valves with a liquid fuel supply and with one end of said metering cylinder on one side of said piston member, and a second hydraulic circuit interconnects each of said liquid flow control valves with an opposite end of said metering cylinder on an opposite side of said piston member and with a plurality of nozzles in the row of nozzles corresponding to the given flow control valve. Means is provided to selectively move each flow control valve to an 'ON' position to permit hydraulic flow through said first and said second hydraulic circuits of the respective flow control valve when the given row of nozzles corresponding to the given flow control valve moves to a first predetermined location under a bed of metallic oxide, and to move each flow control valve to an 'OFF' position to prevent hydraulic flow through said first and said second hydraulic circuits of the respective flow control valve when said given row of nozzles moves to a second predetermined location under the bed of metallic oxide.
