ABSTRACT:
An automatic pressure sensitive regulation assembly and process is provided for use with a non-mechanical particulate solids flow apparatus. The automatic pressure sensitive regulation assembly comprises first and second pressurized fluid distributors. The first pressurized fluid distributor provides incipient fluidization of the particulate solids in the vicinity of the automatic pressure sensitive regulation assembly and an attendant hydrostatic pressure. The second pressurized fluid distributor senses variations in the hydrostatic pressure as a function of the particulate solids level, and in response thereto directly varies the flow of pressurized fluids to the downstream end of the particulate solids flow apparatus to change the rate of flow of particulate solids at the same rate as received.
