An apparatus and method for supplying a controlled flow of fluid transported solid particles, in particular, pulverized coal by the controlled injection of a fluid, such as a gas like compressed air, into at least one feed pipe. The flow of coal in feed pipes is controlled by selectively reducing or increasing the flow of primary air to achieve a balanced burner operation.

An apparatus for controlling the flow of fluid transported solid particles, comprising: a vessel for containing a mixture of primary fluid with suspended particles; at least one feed pipe connected to said vessel for supplying a flow of said mixture from said vessel; means for injecting a fluid under pressure into each feed pipe, said injecting means being situated so that the injected fluid creates a recirculation zone proportional in size to the injection pressure of the fluid in each feed pipe, the size of the recirculation zone proportionally regulating the flow of primary fluid; means for measuring the flow in each feed pipe and establishing a signal indicative thereof, said measuring means being positioned downstream from said injection means; and means for controlling the fluid injection pressure for each feed pipe responsive to the flow signal.
