TL;DR: In this paper, the authors proposed a fuel supply method for a gas turbine combustor having first and second stage combustion chambers, which makes it possible to reduce NO x without deteriorating the combustion performance by stepwise supplying a predetermined flow rate of the fuel when the second stage fuel is to be supplied and at the same time, stepwise reducing the same quantity of fuel that is being supplied from the first stage fuel supply.
