#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 been required. In this podcast we find out how ANDRITZ has developed its new "Lo-NOx" Low Emission Recovery Boiler concept. Hear from ANDRITZ experts Hamilton Brandao, Technology Director Recovery Boilers, Naveen Chenna, Director Research & Innovation Recovery and Power Side Streams and Kasper Skriver, Global Product Manager ESP, about the pilot trials and successful launching of the latest recovery boiler concept as part of the CircleToZero initiative.
