In order to utilize palm acid oil (PAO) for combustion fuel, improvement on the low temperature fluidity of PAO-diesel mixed fuel is demonstrated using polyglycerol fatty acid ester (PFAE). PFAE has an effect on reducing the PAO deposition at low temperature definitely in exchange of viscosity increase. One of the PFAEs: THL-17 puts the aggregation of PAO particles off in the beginning of the cooling in addition to keeping the uniform distribution of the PAO particles. Combustion experiment using an industrial diffusion burner fueled by the PAO-diesel mixed fuel with PFAE is carried out to evaluate the combustion and emissions characteristics. The result shows that the furnace outlet temperature of THL-17:2wt.% mixed fuel almost keeps as high as the temperature of diesel fuel. On the other hand, the THL-17:2wt.% mixed fuel decreases NOx by maximum 30 % in comparison with the diesel fuel, showing a possibility that NOx is reduced by PAO.
