摘要
The invention relates to a method for measuring the properties of a stack (15) that viscous molten salt forms on the bottom of a soda recovery unit (14) while black liquor is burned therein, and for measuring the corrosion of the materials of construction of the unit (14) during the operation thereof. In the method, at least one sensor means (11) is brought into contact with said stack (15), this sensor means (11) being electrically insulated from the soda recovery unit (14). In the method, at least some electrochemical properties and the temperature of said stack (15) are measured with this sensor means (11). The data measured with this sensor means (11) are fed to a measuring and data acquisition unit (12), and said measuring and data acquisition unit (12) is controlled by a control unit (13).
