N2 - Liquid Pretolium Gas (LPG) experimental investigation used to Inverse Diffusion Flame (IDF) burners is presented. The effect of fuel jet velocity on the flame stability and flame temperature distribution of LPG Inverse Diffusion Flame (IDF) was investigated. Fuel jet speed (Vf) = 0.154 m/s and 0.330 m/s was chosen for analysis. Air jet velocity varies from Va = 7.431 m/s to Va = 15.924 m/s for Vf = 0.154 m/s and Va = 8.493 m/s up to Va = 21.231 m/s for Vf=0.330 m/s . The results of the observation show that the velocity of the fuel jet affects the ratio of the velocity of the air-fuel jet which will ultimately have a significant effect on the flame. It was found that the stability of LPG IDF flame at Vf = 0.154 m/s occurred at Va = 11.677 m/s, the equivalence ratio (φ) = 1.99. The stability of LPG IDF flame at Vf = 0.330 m/s occurs at Va = 14.862 m/s with an equivalence ratio (φ) = 1.56. It was observed that the temperature along the IDF centerline increased when the distance from the burner (Z) exit increased. The nature of this temperature distribution shows that central cold air in the air jet is gradually heated towards the IDF downstream. The highest flame temperature is seen in Z between 90-110 mm. It was found that the length of the flame increased with increasing flow of fuel jets. At a constant fuel jet speed the flame length increases but will return again to a certain fuel-air ratio. At Vf = 0.154 m/s the highest flame height is 111 mm and at Vf = 0.330 m/s the highest flame height is 143 mm.
