The objective of the present research study was to determine the flame speed of Camisea-Peru natural gas in a wide range of equivalence ratio through an experimental study. Mathematical calculations were implemented using the method of thermal theory in MathCad. Simulations in a current kinetic mechanism were performed using the CHEMKIN program. Values of flame velocity were 5% to 10% higher than 100% pure methane when compared to other authors in a wide range of equivalence ratio. This validated the results since the gas tested was natural gas with 88.54% methane and 10.32% ethane, thus improving the experimental test bench of the laboratory for the combustion and control of gaseous emissions. In conclusion, the methodology presented here provides an adequate database of gas flame velocity for natural gas of Camisea-Peru.
