The report gives results of intensive tests to establish the level of both gaseous and particulate air pollutants discharged from a controlled-odor kraft recovery boiler. It documents both the cost and emission control capability of such a boiler, designed and erected without direct contact evaporation of the feed liquor. Also investigated were major process variables that affect kraft recovery boiler operation and the emissions resulting therefrom in order to establish boiler operating conditions that minimize emissions. Investigated were boiler loading, liquor sulfidity, and liquor distribution within the furnace. Test data was analyzed statistically by computer, using the multiple regression analysis technique. Particulate emissions were primarily affected by and directly proportional to the amount of black liquor solids burned in the recovery furnace (boiler loading). Both SO2 and total reduced sulfur (TRS) emissions were affected by liquor sulfidity: emissions increased as sulfidity levels increased. This new kraft recovery boiler incorporates the most recent technology for air pollution control, enabling it to meet the Montana state emission standards for both TRS and particulates.
