[Gasification] Steam oxygen coal gasifier operating pressure

[Sunil K Rawal]

what about ash content of coal and what is the carbon content of coal? from
where you got value of operating pressure of  100/.05 bar
I have worked on plasma gasification project and i am unable to understand
what you want to clarify. mass balancing is not proper.
