A cogeneration system is a system supplying multiple types of secondary energy (electricity, steam, etc.)
continuously by driving a gas turbine with primary energy (fuel).

Only pilot fuel is used atthe start-up and in the low
load range(diffusive combustion)

Switching over to DLE begins when
the load reaches a certain level.
The amount of main fuel is increased
DLE combustion range

Supply of pilot fuel isterminated and lean premixed
combustion begins.

The amount of supplementary
firing fuel is adjusted inaccordance with the load.
