Coal lock pressurization

Pulverized coal furnaces are pressurized with carbon dioxide, while Lurgi furnaces are pressurized with gas – are their pressure application methods different? What factors are considered when choosing a gas for inflation? Leaders, take a look :)
The coal grinding and drying units as well as the coal conveying units for pulverized coal gasification require an inert gas environment with an oxygen content of less than 8%, whereas coal feeding into the coal lock in pressurized gasification using crushed coal takes place in a non-inert gas environment
It is determined by the method of feeding, which in turn relates to the safety considerations taken into account during design. Powder coal gasification uses dry coal powder and requires an inert environment to prevent safety issues, whereas the Ruichi process uses lump coal
When pressurizing with syngas, the oxygen content in the syngas isn’t high either.
