| Summary: | Lots of solutions have been offered by scientists to solve dependences on unrenewable energy. One of the solutions that could be offered is by using renewable energy such as biomass. In Indonesia, rice husk is one of the most potential biomass because of its high LHV (14400 kJ/kg) [1] and its availability range is wide since Indonesia is an agriculture country. Gasification process is one way to explore the potential of rice husk. But there is still problems in the gasification process. One of the problems is in the combustion of the gasification’s gas. The problems exist because of low efficiency and low performance of the burner. To solve the problem, high efficiency burner needs to be design with the help of CFD (Computational Fluid Dynamics).<p>This final project goal is to design a new burner with a better performance, which is an improvement from the burner of Willy Adriansyah. Willy Adriansyah’s burner is used as the reference. The first step is evaluation of the reference burner to find improvement prints in the design of new burner. Then, modeling evaluation of the new designs is done to choose the best design, which is the burner that gives the best performance and the best efficiency. The best design is then manufactured and evaluated. The evaluation includes combustion enthalpy, power produced by the burner, and the burner's efficiency. The last step is comparing the performance and efficiency between the new burner and the reference burner to know the improvements that have been achieved and to find new improvements that could be made for further research. The result of this research is a burner with an efficiency of 56,3% and power of 14,253 kW. The new burner has improvements of 25,3% in the efficiency and 5,905 kW in the power compared to the reference burner. Further research could be done to solve the problem of instability of the flame and backflow. <br />
