The Simulation of Biogas Combustion in A Mild Burner

Blog Article

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 click here 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 the gel bottle audrey 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%.
