ABSTRACT:
There is provided a slagging combustion system for generating high purity working fluid suitable for driving gas turbines. The system consists of a precombustor for preheating oxidant tangentially fed to a primary slagging combustor where a solid carbonaceous material is combusted under substoichiometric slagging conditions. Slag is collected in the primary slagging combustor and products of combustion passed to a transition section where tertiary oxidant and sulfur-gettering agents are added, and then to a cyclonic secondary combustion chamber.
