摘要：
Full-scale black liquor spraying experiments were carried out at three spraying 14 temperatures and three mass flow rates with high solids content black liquor. We studied the spray disintegration mechanism, the length of the sheet, and estimation of drop size from the wavelength of a black liquor sheet. The flash-dominated disintegration mechanism produced a very short uniform sheet. 14 We observed wave formation and perforation in non-flashing cases. An image-analysis-based algorithm to measure the sheet length was developed and tested. Fast Fourier transform and autocorrelation functions were tested to find the dominating wavelength of the spray to predict the final drop size.
