Dry Low Nox Combustion AKA DLN1 emission control technology is used in heavy duty gas turbine developed by GE
Mode/Operating Range
■Primary-- Fuel to the primary nozzles
only. Flame is in the primary stage
only. This mode of operation is used
to ignite, accelerate and operate the
machine over low- to mid-loads, up to
a pre-selected combustion reference
temperature.
■Lean-Lean-- Fuel to both the primary
and secondary nozzles. Flame is in
both the primary and secondary
stages. This mode of operation is used
for intermediate loads between two
pre-selected combustion reference
temperatures.
■Secondary -- Fuel to the secondary
nozzle only. Flame is in the secondary
zone only. This mode is a transition
state between lean-lean and premixra modes. This mode is necessary to
extinguish the flame in the primary
zone, before fuel is reintroduced into
what becomes the primary premixing
zone.
