Many mills have increased the as-fired black liquor solids in order to improve their boiler’s thermal efficiency, increase liquor throughput and [...]]]></description>

		<description><![CDATA[Pulping methods and conditions have a pronounced effect on the viscosity of black liquor. For example, black liquors from (PS+AQ) pulping are lower in carbohydrate content, and are expected to have lower viscosities (if the liquor REA stays relatively constant). They also have lower organic/inorganic ratios and lower heating values. If liquor firing parameters are [...]]]></description>

		<description><![CDATA[Mills that do not separate soap for tall oil production can have high soap content (around 2.5%) in their black liquor. The soap will increase the heating value of the black liquor, which may be advantageous if the boiler is not steam limited. Other beneficial effects include a reduction in chemical make-up, increased bed temperature [...]]]></description>

		<description><![CDATA[The viscosity of black liquor determines its handling properties, and is a critical parameter for the control of a recovery furnace. Viscosity is also an important factor in black liquor evaporation, as it affects the heat transfer rate. An increase in viscosity can lower the evaporation capacity. Softwood black liquors (e.g., pine) generally exhibit near-Newtonian [...]]]></description>
