#19 What are the possibilities to 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.
In general, emissions from the recovery boiler have decreased substantially over the last decades, for instance CO2, dust and sulfur emissions, however in the case of NOx emissions new technology has...
