Latest Patents

Gunnar Hage holds a patent for a method titled "Control of a black liquor recovery boiler." This invention focuses on controlling the combustion and reduction processes in a black liquor boiler of a paper pulp plant. The method influences the feeding of black liquor to the recovery boiler using a black liquor gun. A key characteristic of this method is the control of the average thickness of the black liquor flow layer immediately after it exits the gun. This thickness is measured indirectly through a droplet index (DIX), which is determined by the viscosity, density, and feed rate of the black liquor, as well as the shape and opening area of the gun. Hage's innovative approach enhances the operational efficiency of black liquor recovery systems.
