High-pressure coal powder transportation
Thread Content
I recently received a project involving the feeding of coal powder into a gasification furnace. There is a back pressure of 40 KG in the furnace – has anyone dealt with this before? Is it feasible to use pneumatic conveying?
Hehe, take a look at Shell’s approach to see if we can draw some inspiration from it, hehe
Of course it’s feasible; both SHELL\GSP use high-pressure N2 or CO2 to effect dense-phase transport via pressure difference into a vaporization furnace with a backpressure of 40 kilograms
It should be feasible; the original poster can draw on Shell’s concept of dense-phase transportation, and disc valves could be considered for the valves.
What kind of valve is a disc valve? Can it withstand a pressure of over 40 kilograms? What kind of valves does SHELL use?
Gas transportation is the preferred method; for the transportation of dry coal powder, pneumatic transportation under positive pressure is almost always used, as negative pressure suction is not suitable.
It depends on which furnace it’s sent to; they’re different； Another point is that the type of coal delivered makes a big difference.
