Abstract
A method for restoring slagging conditions in a substoichiometric slagging combustor first requires the establishment of a threshold condition below which an unacceptable risk of slag outlet pluggage exists. Upon observation of current slagging conditions below the threshold conditions, substantially pure oxygen is injected into the combustion reaction zone to increase both zone temperature and reaction rate, leading to improved slagging conditions within the slagging combustor.
