Abstract
Apparatus and a method for delivering materials such as comminuted rubber tires as a secondary fuel to a combustion chamber of a furnace or kiln. A hopper includes a variable speed electric motor-driven screw conveyor, and a control system provides a variable frequency alternating current to the motor of the screw conveyor to deliver a metered amount of fuel from the hopper. A blower and a nozzle assembly may be used to entrain the fuel in a stream of air and carry the fuel to the combustion chamber where it is required. The fuel is delivered in metered quantities in response to the required firing rate of the furnace or kiln. A second metering device provides metered quantities of material which can be carried by the fuel to be taken into a high temperature environment to be decomposed or burned. The apparatus is mounted on a transportable platform.
