In this study, the laminar burning velocity of low calorific gas fuels are verified through the comparison and examination of experimental and predicted results. The bunsen burner which has contraction nozzle is used to measure the laminar burning velocity with the cone angle method. In addition, PREMIXED code combined with two mechanism, i.e., the GRI 3.0, and USC II reaction mechanisms is used to predict the laminar burning velocity. As heating value decrease, the laminar burning velocity correspondingly decreases due to inert gases in the fuels. Through the comparison and analysis of the experimental results and the predicted results, it is confirmed that LCF 9000 and LCF 8000 with the GRI 3.0 reaction mechanism and LCF 7000 and 6000 with the USC II reaction mechanism have a similar distribution of laminar burning velocity between the experimental result and the predicted result. This similarity is due to a large amount of propane, which is not suitable for the GRI 3.0 reaction mechanism in LCF 7000 and 6000.
