The GTS MTB burners are gas burners with Metallic Tube used for direct heating. The burner produces an intense flame that allows high heat penetration and better temperature uniformity inside the combustion chamber. The MTB burners are “Nozzle Mix” type burners. The fuel gas and combustion air is mixed at the combustion head to avoid flashbacks. The burner is suitable for regulation in stoichiometric, excess air or reducing air-to-fuel gas ratio.
