<p>Fluidising transport apparatus comprises a hopper 2, a pressure vessel 4 and a valve element 8 which controls a port 6 between the hopper 2 and the vessel 4. The valve element 8 is retained closed against the port 6 under pressure within the vessel 4. A fluidising nozzle 14 receives transport fluid, such as water from a fluid line 16. Water supplied through the fluid line 16 thus fluidises solids 32 in the vessel 4 and raises the pressure to maintain the valve element 8 in the closed position. The fluidised solids material is then supplied to a transport pipeline 24 from the vessel 4. Solids material loaded into the hopper 2 depress the valve element 8 when pressure within the vessel 4 is relieved, so allowing a fresh charge of the solids material 32 to enter the vessel 4 for a subsequent cycle.</p> |
