IGCC technology has been drawing attention as the upcoming alternative energy source to generate electric power for a few decades. It is because its higher efficiency and possibilities for using low rank coal and adapting carbon capture and storage. In this research, Pilot scale two-stage gasifier was used to evaluate the performance. The produced syn-gas qualities like temperature, composition and flow rate were monitored to find the effect of different coal feed rates and supplied steam quantities on the gasifier performance. And, the ABK coal from Indonesia was selected for the test as one of the sub bituminous coals. Coal feed rates to the second stage burners were changed from 10% to 90% of supplied coal to the main burners.
The results demonstrate that increasing steam and coal feed rate to the second stage burners make the temperature of produced syngas reduce. Furthermore, the composition of syngas was also changed. H<SUB>2</SUB>(hydrogen) and CO<SUB>2</SUB>(carbon dioxide) was increased but CO(carbon monoxide) and CH<SUB>4</SUB>(methane) was decreased. In the case of cold gas efficiency was increased slightly as the steam and coal feed rate increased. Through this research, coal feed rate to the second stage burners was recommended up to 30% of total coal feed rate.
