O-22 Grindability evaluation of carbonized PKS

Abstract

Palm Kernel Shell is the biomass resource which is generated in large quantities in Indonesia and Malaysia. But PKS is very difficult to pulverize, it is necessary to improve grindability of PKS to use PKS at PC boiler with coal. So, we tried to improve PKS's grindability by low temperature carbonization technology. We produced carbonized PKS of varied VM, and we evaluated these grindability. As results, we have demonstrated 11 cal.% biomass co-firing by using carbonized PKS at the 216 MW commercial power plant.
