The study of combustion and contaminant emission of black liquid coal-water slurry
黑液水煤浆的燃烧和污染排放特性研究

The coal-water slurry(CWS) is introduced into treating the paper-making black liquid. The black liquid is regarded as a resource to achieve the no-emission. The thermogravimetric analysis on the black liquid coal-water slurry (BLCWS) shows that the characteristics are the lower kindling point and the better property of burnout. The combustion in the industrial boiler shows that the combustion efficiency(97.31%) is high, and the contaminant emission is within emission standard of air pollutants (emission concentration of SO2 is 67mg?m-3).
