Sludge palm oil (SPO) is one of the wastes produced during the activity of palm oil milling process. The most common method to synthesise biodiesel from SPO is through a chemical process known as esterification and transesterification. The chemical process required additional cost and time. Hence this paper aims to evaluate the utilisation of SPO directly as fuel in burner system and compare with conventional diesel. The SPO studied contain free fatty acid (FFA) content about 30 %, density and viscosity at 0.982 g/cm3 and 67.76 mm2/s respectively which is higher than diesel. The maximum combustion temperature achieved was 869 °C lower than diesel, 891 °C. Lower CO, CO2 and NOx emission during combustion compare to diesel around 34 %, 6% and 90 % reduction respectively. The low combustion temperature, flame length and emission due to the high viscosity of SPO compare to diesel. Fuel spray and flow was affected by viscosity which lowers the combustibility and consumption of SPO. SPO show great properties and combustion performance as fuel for burner system and improvement can make it even better.
