Evaluating the effect of recovery boiler operation of green liquor dregs concentration using multivariate analysis
نویسندگان
چکیده
Poor settling and filterability of green liquor dregs has been a persistent problem in many kraft pulp mills. While the concentration settling/filtering behaviors are expected to be related how black is burned recovery boilers, effect boiler operation not well understood. A systematic study was conducted examine may affect raw (RGL) at three mills using SIMCA, multivariate data analysis (MVDA) program. Daily average operating from were analyzed over 3-year period. Results both principal component (PCA) partial least squares regression (PLS) suggest that main operations contributing high concentrations RGL low firing load, bed temperature, poor char burning, unstable bed.
