4 Conclusions

We present an experimental study on a swirl-stabilized, LPG - air, and methane - air-

fueled dump plane combustor. Experiments carried out at different fl ow rates

varying from 70 to 200 lpm with varied degree of fuel air premixing. Equivalence

ratios are also varied from stoichiometric to LBO limit. Studies have been carried
