In a recovery boiler having a plurality of air inputs, with the primary air input closest to the bed of the boiler, a fuel input, a smelt output, and an exhaust output, a method of controlling the combustion of fuel in the boiler to operate at the maximum reduction efficiency. The method includes the steps of measuring the amount of sulphur dioxide at the exhaust output; and varying the amount of air entering into the boiler through the primary air input until the minimum amount of sulphur dioxide is measured at the exhaust output.
