Coal Gasification - an overview | ScienceDirect Topics

Coal gasification is a process in which coal is converted to a low-grade gas; it can be regarded in many ways as fuel-rich combustion. Oxygen-blown coal gasifiers operate at overall equivalence ratios (fuel to oxidizer ratio normalized by fuel to oxidizer ratio required to fully oxidize fuel) greater than two.
