The invention relates to a method of measuring dry substance in the flue gas in liquor recovery units in mills for the manufacture of papermaking pulp in order thereby to render it possible to control the operation of the unit. According to the invention, this is carried out in that the radiation emission caused at the combustion of fuel particles in the hearth of the unit above the fuel supply level is detected optically, and that the signals are used for indication and/or control of the operation of the unit.
