Fundamental studies of black liquor combustion: Report No. 2, Phase 1 (October 1984-November 1986)
The fundamentals of kraft black liquor combustion are being studied in a five year project. This report covers the second and third years of work by The Institute of Paper Chemistry (IPC) and the National Bureau of Standards (NBS) for the US Department of Energy. The burning processes are being studied in two continuous flow reactor systems designed to both study overall process and single particle phenomena. Black liquor burning is divided into four distinct phases: drying, volatiles burning, char burning, and smelt coalescence. Phase 1, In-flight Processes, is the main focus of this report. In-flight processes include mainly the stages of drying and volatiles burning. Testing results in both flow reactors and in two specially designed single particle reactors are presented. Dynamic droplet velocity and swelling have been measured for the first time. A direct link between initial liquor viscosity and burning behavior in the early stages has also been identified. During the fourth year Phase 1 will be completed and Phases 2 (Char Burning) and 3 (Fume Processes) will begin.
