<p>(57) The invention relates to a method of regulating, for the purpose of burning in the soda-ash furnace, the feeding-in or combustion conditions of concentrated spent liquors of varying chemical and physical properties by measuring some physical property of the liquor fed into the soda-ash 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 expansion, upon heating, of a dry-matter particle of the liquor fed into the soda-ash furnace is measured. On the basis of this measurement the temperature, pH value, or injection pressure of the liquor fed into the soda-ash furnace, or the height of the injection point, or the feeding of air into the soda-ash furnace is adjusted directly on the basis of the maximum expansion measurement.</p> |
