Biodiesel is fuel consisting of mono-alkyl ester mixture from fatty acid long chain, which is used as alternative fuel for diesel engine and made from renewable resources such as vegetable oil and animal fat. In many companies that still use diesel fuel for their oil burner, biodiesel is the right alternative fuel because it only needs relatively small investment compared to other alternative fuel such as LNG, residue, or coal. Despite the ease, usage of biodiesel actually causes unwanted effect on engine performance, especially the high deposit forming rate. One of solutions that we can do to overcome the problem is by using fuel additives. This method is considered as an economical one because we don’t need to modify the engine. With low treat rate, fuel additive can improve engine performance that uses biodiesel as its fuel. In this experiment, we use detergent additive that contains nitroparaffin and other specialty chemicals. This additive is specially developed to improve biodiesel quality, claimed that this additive can help reduce emission, fuel consumption, and deposit forming in injector head up to 90%. The aim of this experiment is to find out effects of additive usage on oil burner performance that uses biodiesel mixture as its fuel. The experiment was carried out by using Olympia burner and customized chimney installation and located at ITB’s incinerator in Sabuga. Deposit identification was held at Laboratorium Uji Material, Departemen Metalurgi dan Material FTUI. From the experiment, it is found that usage of detergent additive on biodiesel mixture can reduce deposit forming rate and fuel consumption. For flame dimension, 1000 ppm of additive usage on B05 and B20 & 2000 ppm of additive usage on B10 can increase the flame parameter. For emission issue, additive usage on B05 and B10 increased the CO and HC emission, and reduce those emissions on B20. From the data that has been collected, we can observe that additive performance is influenced by treat rate and its basic substance.
