Numerical Study of LPG Combustion affected by Y- shaped Nozzle mounted on Slot Burner

This research is to study the LPG combustion affected by Y-shaped nozzle mounted on slot burner. The Y-shaped nozzle is a burner outlet which controls the air and fuel flow on the slot burner. In order to increase temperature by improvement of the mixing between air and fuel over the burner, the Y-shaped nozzle mounted on the slot burner was designed and investigated by numerical method. This study focused on main parameters as 15, 30, and 45 degrees of air circulating cavity angle with/without air strengthening hole by numerical simulation model at equivalence ratio Φ =1.0 and 2.0 kW of firing rate. As the result, more 150C (11.0%) of maximum flame temperature was increased with Y-shaped nozzle slot burner mounted with 45 degrees of air circulating cavity angle and added air strengthening hole. This study shows the enhancement of LPG flame temperature influenced by the Y-shaped nozzle mounted on the slot burner due to the improvement of the turbulence flow mixing.
