Abstract

Combustion, 


Methane,


Burner

This paper deals with combustion of premixed and diffusion methane flames. Temperature and emission measurements of premixed and diffusion methane flames have been carried out in the present study. A new combustion system including burners and combustor has been designed and manufactured in order to determine the temperature and emission values of methane flames throughout the combustor. This combustion system includes burners, combustor, gas and air lines, regulators, manometers, flowmeters and so on. Premixed and diffusion burners with a capacity of 10 kW have been used so as to burn the methane during the experiments. Temperatures have been determined by using thermocouples throughout the combustor. Emission values have also been measured via a flue gas analyzer throughout the combustor. The results show that the maximum flame temperatures have been measured as of 1230°C under the premixed flame conditions and as of 1193°C under the diffusion flame conditions. When it comes to emission measurements, it may be said that the maximum NOX and CO2 emission levels form in the flame region while minimum CO formations emerge in the same region under the premixed combustion conditions due to the complete combustion conditions in the premixed burner. Therefore, it can be concluded that complete combustion has been nearly achieved by the premixed methane burner.
