Green and Black Liquor Heating in Pulp & Paper Mills

Use direct steam injection for black and green liquor heating to improve slaker efficiency and avoid plugging and fouling.

Green Liquor Heating – Slaker Efficiency

» Precisely control green liquor temperature
» No scaling or fouling
» Low maintenance

Black Liquor Heating

» Heat solids over 70% without fouling or
plugging
» Smooth, stable operation even at reduced
liquor flow during boiler startup
» Accurate temperature trim heating

Stripper Tower Water Heating

» Optimum temperature control
» Efficient absorbency of gas pollutants
» Eliminate fouling and maintenance issues,
common with heat exchangers
