This paper presents the results of field demonstration for fuel switching to bio-fuel oil in 4 commercial heavyoil fired power plants. The 100% fuel switching field demonstration was successfully carried out in twotangential-firing boilers at a capacity of 75 and 100 MWe respectively without major equipment retrofit, andalso 25% bio-fuel oil blending for two opposite firing boilers at a capacity of 350 and 400 MWe respectively. Despite the low density and heating value, the bio fuel was successfully replaced heavy fuel oil at the fullload by only adjusting operational parameters. Incase of bio fuel oil combustion, heat absorption of radiativeheat transfer section was reduced while convection section has opposite trend. In pollutants emission, amajor reductionin SOx as well as 10-20% reduction in NOx were achieved by the fuels witching. On theother hand, boiler efficiency was slightly underestimated.
