Abstract

This paper discusses the design and development of moderate and intense low oxygen dilution (MILD) combustion burners, including details of the computational fluid dynamics process, step-by-step from designing the model until post-processing. A 40 mm diameter bluff-body burner was used as the flame stabilizer. The fuel nozzle was placed in the center with a diameter of 1mm and an annular air nozzle with an opening size of 1,570 mm2, and four EGR pipes were used. Non-premixed combustion with a turbulent realizable k-epsilon was used in the simulation. The fuel used is low calorific value gas (biogas). The synthetic biogas was a mixture of 60% methane and 40% carbon dioxide. The simulation was successfully achieved during the MILD regime where the ratio of maximum-to-average temperature was less than the required 23%.
