Method of measurement of properties of a stack and corrosion of materials in a unit of recovery of caustic soda

摘要

Invention patent: b '' method of measurement of properties of a pile and corrosion of materials in a unit of recovery of soda '' d .The present invention relates to a method of measuring the properties of a stack (15) in which viscous molten salt is formed in the bottom of the soda recovery unit (14) while black liquor is burnedOf the same, and to measure the corrosion of the materials of construction of the unit (14) during the operation of the same.In the method, at least a device sensor (11) is brought in contact with the battery (15), this device sensor (11),Electrically isolated from a soda recovery unit (14).In the method, at least some electrochemical properties and the temperature of the battery (15) is measured with the device sensor (11).The data measured with this device sensor (11) are fed to the unit of acquiring and measuring data (12).And the unit of acquiring and measuring data (12) is controlled by the control unit (13).
