What is “FGI”?
FGI is an acronym for Fuel Gas Injection. Just as the name implies, Fuel Gas Injection is a method by which supplemental fuel, typically natural gas, is injected into the VOC contaminated process upstream of the RTO to boost the process fuel value to a “fuel-free” operation level. The advantage of Fuel Gas Injection is reduced supplemental fuel consumption and operating costs since combustion air from the burner is not needed. Also, since the burner is not needed, the NOX generation is negligible. Fuel Gas Injection should be reserved for processes where the fuel value of the VOCs being destroyed is less than that required for “fuel-free” operation.
