Abstract
A method and apparatus for controlling the viscosity of slag contained in a rotary incinerating kiln by detecting the position at which the slag exits the outlet of the kiln, thereby determining changes in the viscosity of the slag. If the viscosity deviates from a predetermined range of values, appropriate additives are supplied to the slag for bringing the viscosity back to within the range of the predetermined values. There is also disclosed a method and apparatus for measuring viscosity as 'angular' viscosity.
