Reduce NOx emissions from recovery boilers

Often described as the “beating heart” of a pulp mill, the recovery boiler has come a long way since it was first invented nearly 100 years ago. Although recovery boilers carry out a virtually irreplaceable function at pulp mills, including the recovering inorganic chemicals, burning organic chemicals and recovering heat for generating energy, there is still work to be done when it comes to emissions - especially NOx emissions.
