CONTINUOUS HIGH PRESSURE SOLIDS PUMP SYSTEM

摘要

A system and method for continuously supplying solids from a lower pressure storage reservoir (10) to a higher pressure feeder tank (30) for use in an application such as a blast furnace (40) employs a high pressure variable speed solids pump (20). A fluidizing device discharges solids in a dense phase flow to a deaerating device (15) for deaerating the solids flow prior to entering a variable speed high pressure solids pump (20). A feeder tank (30) having an outlet (31) is connected to the outlet (21) of the solids pump (20) and the feeder tank (30) is at a higher pressure than the source of the solids.
