Ash Fusion Determinator – EATC16 Series (Up to 1600 °C)

The Ash Fusion Determinator is a precision analytical instrument designed to determine the fusibility temperatures of ash derived from coal, coke, biomass, refuse-derived fuel (RDF), and solid biofuels. The EATC16 Series, including the EATC16 Manual, EATC16, and EATC16plus, complies with major international standards such as ISO, ASTM, CEN/TS, DIN, and CEN/TR.

These instruments automatically determine the four critical ash fusion temperatures:

  • Initial Deformation Temperature (IDT)

  • Softening Temperature (ST)

  • Hemispherical Temperature (HT)

  • Fluid Temperature (FT)

By continuously monitoring sample deformation and comparing it with applicable standards, the system enables accurate, repeatable identification of ash fusion points, supporting reliable fuel characterisation and combustion performance evaluation.

High-Resolution Imaging & Analysis System

A high-resolution integrated camera with a manually adjustable lens is mounted on a movable arm, allowing precise observation of samples while providing unobstructed access to the furnace work tube. The live video feed is recorded and displayed on a high-performance computer using a dedicated logging and analysis software.

Advanced image analysis features include:

  • Grid overlay for precise comparison of sample height and width

  • Continuous image capture at every 1 °C temperature increment (EATC16 & EATC16plus)

  • Support for standard specimen shapes, including cylinder, pyramid, upright pyramid, and truncated pyramid
