Impacts of Firing High Solids Black Liquor on Kraft Recovery Furnace Nitrogen Oxides and Sulfur Dioxide Emissions – A Review (WP-21-04)

This white paper reviews the literature on the impact of high solids black liquor (HSBL) firing in a kraft recovery furnace on furnace sulfur dioxide (SO2) and nitrogen oxides (NOx) emissions. Past literature has confirmed that HSBL firing in kraft recovery furnaces is undoubtedly beneficial for controlling furnace SO2 emissions,…
