The aim of the present work is to study and test flame stability and blow off for natural gas by use two design for conical stabilizer to enhance the swirl phenomena through the combustion. An experimental test rig is used to study the effect of the two designs of conical stabilizer on flame stability. In the present work flame stabilization using conical stabilizer is investigated to study the flame stability limits for a free jet premixed flame burner. The stability limit (blow off) is examined through changing some parameters in particular of the inclination angle of exit jet of conical stabilizer. The effect of these parameters on the flame stability discussed. The measurements of experiment is mainly depends on visualization. So that an experimental test rig is constructed to fulfill these objectives and different measurements are recorded and analyzed. The study showed that the conical stabilizer has improved the flame stability extend of free flame. The conical stabilizer case I has an effect on the stability limit more than on the conical stabilizer case II. The exit jet with angle on vertical axis for higher velocities of the premixed mixture. |
