Progress on Biomass Coal Co-firing for Indonesia Power Plant

PT. PLN Indonesia Power (PLN IP) collaborated with other research institutions has conducted several studies to investigate the possibility of using biomass for co-firing with biomass in coal power plant. This review paper integrates results of the previous study results carried out by the authors. Biomass has some disguise disadvantageous such as low energy density, high alkaline metals, high volatile mater, handling difficulties, which may cause derating in power plant and some problem in the combustion facilities such as slagging, corrosion, abrasion, and agglomeration. The investigation carried out reveals that the use of multi-type biomass could eliminate the derating. The pre-treatment of the biomass such as drying and pelletizing could improve not only the energy density but also diminishing the slagging potential.
