A method and system for combustion of fuel in a boiler in which flue gasses are produced The boiler includes a source of fuel a source of air, and a controller for controlling the ratio of the source of air and the source of fuel inputted into the boiler. A sensor is used for measuring the concentration of oxygen in the flue gasses. The controller is adapted to calculate the amount of air entering the boiler based on the amount of oxygen in the flue gasses to thereby adjust the air to fuel ratio to include calculated air input and air input from the source of air. A preferred fuel is pulverized coal The method and system provide for the air to fuel ratio to be adjusted to optimize efficiency as well as to minimize NOx production.
