Abstract
Both method and apparatus are disclosed for controlling the distribution of powdered solid fuel to one or more burners. The powdered solid fuel is caused to pass downwardly through an air current passing from an air inlet to one or more outlet ports. The total rate at which fuel is distributed is controlled by the rate at which air is supplied to the air inlet. In addition, each outlet port is provided with an individual adjustment for controlling the relative rates at which fuel is supplied through the various individual outlet ports. The construction of the distributor is such that the system may be controlled to distribute fuel continuously or in successive controlled impulses while at the same time controlling both the total amount of distributed fuel as well as the relative amounts of fuel distributed in the various outlet lines to the burners. The preferred distribution apparatus utilizes only components which are stationary and motionless with respect to one another during normal operation so as to avoid the disadvantages otherwise caused by the interaction of the powdered solid fuel particles and moving apparatus components.
