REGULATING METHOD OF FEED QUANTITY IN DISTRIBUTIVE TRANSPORTATION

PURPOSE:To quantitatively perform multi-distributive transportation, in a method for supplying pulverized coal to a blast furnace from a pressure vessel, by constituting a device such that a booster low is changed for each booster piping to regulate a feed quantity to each transport pipe per unit time. CONSTITUTION:Pressurized gas is supplied in a pressure vessel 10 from a pressurized piping 19, and maintained at constant pressure. Under this condition, a flow of gas in booster pipings 11-15 is changed individually by each flow regulator 8. In this way, relations between compressed gas pressure drop, frictional pressure drop of granules in the transport pipe, terminal pressure of transport pipe and transport pressure in each transport pipe 1-5 can be changed, and a transport amount of each transport pipe 1-5 can be controlled. In this way, uniform distribution and transport amount adjustment of the desired transport pipe can be easily and selectively achieved.
