Temperature Profile Measurement in Non-Premixed Turbulent Flame Near Lean Limit of LPG/Air Mixture

Abstract

The current research was carried out on the topic of non-Premixed turbulentflames.The temperature profile of non- premixed turbulent flame of lean LPG/Airmixture were obtained.A simple jet burner with two different inside diameter and having two differentperforated plates was designed in order to achieve turbulent flow .The temperature was obtained at the two diameters and different positions forperforated plates. The temperature profiles were obtained by using a finethermocouple ( 0.2mm diameter ) at height ( 3mm ) above the burner mouth. Themaximum temperature for all cases was found at flame edge, and start decreasingfor both sides .
