Abstract
Powdered particles are continuously distributed from a pressurized transporting vessel to a plurality of receiving ends such as tuyers of a blast furnace through a plurality of transporting pipes for each receiving end. A speed of gas supplied to the vessel is controlled depending on a weight changing ratio of the vessel and an internal pressure of the vessel, so that the speed of gas is maintained at constant. Booster gas is supplied to each of the transporting pipes. A discharging rate of the powdered particles is controlled by a cascade control system for each of the pipes by individually controlling a flow rate of booster gas depending on a differential pressure in each discharge nozzle of the pipes, or on an output of solid-gas mass-flow meter in each of the pipes, or on a solid-gas ratio corresponding to each length of the pipes and a mass-flow rate of the particles in the vessel per total gas flow rate.
