<p>A high performance, multi-stage, pressurized, airblown, entrained flow coal gasifier system (10) and a method of operating such a gasifier system (10) for generating therewithin fuel gas from coal. The subject gasifier system (10) includes an outer, pressure containing vessel (14) surrounding an inner, water-cooled vessel (12) wherein the gasification reaction, through which the fuel gas is generated from coal, takes place. The inner, water-cooled vessel (12) embodies a first stage (22) within which the high temperatures required for the gasification reactions to take place as well as for slagging are generated from the combustion of char, a second stage (24) within which the char is gasified to generate the subject fuel gas, and a third stage (26) within which coal is devolatilized to produce the char for the first stage (22) and the second stage (24) and with a concomitant quenching being effected of the fuel gas as the latter flows through the third stage (26) of the inner water-cooled vessel (12).</p> |
