    Then, millers discovered that black liquor could provide a reliable, abundant energy source. Since the 1930s recovery boilers have allowed the recovery and reuse of the byproduct to extract energy from the pulping residues. Many boilers were installed in the 1960s and 70s that are still used to create steam from the recovered black liquor.Learn More

  • Black Liquor - an overview | ScienceDirect Topics

    The black liquor must be concentrated to as high a solids content as possible before being burned in the recovery boiler to maximize the heat recovery. The viscosity rises rapidly with concentration above 50%, with softwood black liquors being more viscous than hardwood black liquors. Black liquor is usually fired at 65%–70% solids content.Learn More
