Method for adjusting the concentration of sulfur dioxide in flue gases.

摘要

Method for adjusting the concentration of sulfur dioxide in flue gases, wherein in a washing tower (2) the gas is fed to purge a suspension washing (6) containing water and lime in suspension washing (6) an oxidizing agent is blown gas purified, poor in sulfur dioxide exhaust is evacuated and the content of sulfur dioxide gas to be purified and / or purified exhaust gas is measured continuously or at intervals predetermined time, wherein the oxidizing agent blown into the washing suspension (6) is enriched and / or replaced, at least partially, with pure oxygen, orienting the magnitude of the enrichment and / or replacement to the necessary reduction of the content sulfur dioxide.
