Coal powder transfer pump

This post was last edited by lflsedin on 2015-11-27 at 22:04. Currently, the feed systems for pulverized coal gasification use high-pressure gas transmission. However, abroad, a type of vane-driven pump is being studied; it resembles a water pump. Coal powder enters the pump at low pressure and exits it at high pressure, with the mechanical power of the pump itself being used to overcome the pressure difference between the inlet and outlet. Due to this pressure difference, the pump must have excellent sealing properties. I wonder if there are any studies on this topic in China, and whether anyone is aware of information related to it?
You mean something similar to the principle of a Fuller pump, right?
I hope such a pump exists, as it would **reduce the investment required for air separation**
Pratt & Whitney in the United States is conducting research in this area and has already achieved results; everyone should pay attention to it! Planned for use in PWR gasification.
It seems that GE is also conducting research in this area. Its effect is to replace the current coal lockhopper, but it’s unknown what the results will be How is the system configuration?
I’ve also been paying attention to this issue recently; I hope we can discuss it more. My QQ number is 375895689 – feel free to add me if you’re interested
Who has the schematic? The HYGAS is a good furnace for oil-coal slurry
