Abstract:
1. A system for distributing particulate matter comprising: at least two conduits, each conduit extending from a common first position adjacent a source of particulate matter to a second position, the pressure differential between the first and second positions being substantially the same for each conduit; a pressurized fluid for conveying particulate matter through the at least two conduits; a device for measuring a mass flow of particulate matter in each of the at least two conduits; and a controller in communication with the device, the device further providing additional pressurized fluid to each conduit having a solids ratio greater than the desired solids ratio of the at least two conduits in response to the measured mass flow to balance or to preferentially bias the mass flow of particulate matter through each of the at least two conduits; wherein the controller maintains each conduit by monitoring that each conduit satisfies the equation:
