Abstract: The invention relates to a method of regulating, for the purpose of burning soda-ash in a recovery boiler furnace, the feeding-in or combustion conditions of concentrated spent liquors of varying chemical and physical properties by measuring some physical property of a liquor fed into the recovery boiler furnace and by regulating the feeding-in and combustion conditions directly on the basis of the thus measured physical properties. According to the invention, the maximum swelling, upon heating, of a dry-matter particle of the liquor fed into the recovery boiler furnace is measured. On the basis of this measurement the temperature, pH value, or injection pressure of the liquor fed into the furnace, or the height of the injection point or the direction of injection, or the feeding of air into the furnace is adjusted directly on the basis of the maximum swelling measurement.

Abstract: PURPOSE: To easily and reliably determine the expansion of a concentrated waste liquor by using the concentration ratio of the lignin to at least one acid present in the liquor as a measure for the expansion. CONSTITUTION: Based on the fact that there is an interdependent relationship between the expansion of a concentrated waste liquor and the concentration ratio of the lignin to acid (s) present in the liquor, the expansion is determined by measuring the concentration of the lignin and the (total) concentration of one or several acid (s) in a concentrated waste liquor. Based on the measurements, the feed conditions of the concentrated waste liquor can be regulated by controlling the chemical or physical properties of the liquor.
