Introduction. Replacing some of the coal by biomass is an effective way to reduce CO 2 emissions from pulverizedcoalfired power plants and integrated coal gasificationcombined cycle power plants. However, compared with coal, biomass has lower grindability in the existing roller mills 1 and a lower calorific value per weight. 2,3 The maximum biomass cofiring ratio for stable operation is ...
