Burners / Injectors: Gaseous Fuels

FT FLEX GAS INJECTOR
Underport Burner

FT Flex unique dual-gas inlet injector-type burner promotes optimal combustion due to fully independent and reproducible control of inner and outer gas flow. This design for gas distribution control creates ultimate flexibility, optimal heat transfer (due to more soot) and extremely low NOx emissions.
