Abstract
An ash fusion analyzer for determining the ASTM defined fusion temperatures of coal and coke ash includes a furnace chamber with a viewport. A rotatable sample-supporting platform is positioned within the chamber such that samples on the platform are viewable through the viewport. An optical system is aligned with the viewport for directing images of the moving samples onto a solid state line scan array. A microprocessor is coupled to the array for periodically sampling data from the array and calculating shape information relating to the samples.
