摘要
Conveyor gas is passed through a conveyor conduit to convey bulk material therethrough, while clean gas is passed through a by-pass conduit connected to the conveyor conduit at positions spaced along the length of the conduits. The by-pass conduit can be divided into a plurality of sections by shut-off valves which close in response to a predetermined pressure difference between the two conduits, with a reduced pressure in the conveyor conduit due to a blockage of material therein. Due to the pressure difference, clean gas is transferred from the by-pass to the conveyor conduit at a plurality of said connections between the two conduits, only in the respective section in which there is the pressure difference.
