Utilizing pure hydrogen as an energy source is becoming more realistic as technology is advancing. Hydrogen has been historically difficult to produce, store, and transport. Natural gas is the main clean energy source currently. It is composed of mainly methane. Methane is made up of a carbon atom and four hydrogen atoms. When methane is burned to create heat in industrial processes, carbon emissions are released. This contributes to climate change. Burning pure hydrogen does not produce carbon emissions. Burning hydrogen, especially with the current infrastructure, has potential issues. This thesis investigates the combustion of a mixture of hydrogen and natural gas. This will better suit the current infrastructure and produce less pollution than just burning natural gas. This thesis will focus on the stability of laminar premixed combustion of different mixtures of hydrogen and methane. An issue with combustion is stability. There is generally a stability window in which a flame will be stable. This can be influenced by the flow rate, medium in which combustion is occurring, type of combustion, and oxidant-fuel ratio. This will provide theoretical stability limits based on the mass flow rate for each mixture. Stability limits are important as they set the limits for flow rate and Oxidant-Fuel ratio. There are improvements that can be made with the physical combustion medium to improve these limits. This thesis utilizes Ansys Chemkin. The Chemkin code utilized in this thesis was confirmed utilizing a peer reviewed article. This is a numerical study that can provide theoretical predictions based on calculations.
