Key Features
The instrument features an automatic temperature recording along with images of the Ash Cone using a high Resolution CCD camera. The camera collects and records the images of the Ash Cone as it deforms with increase in furnace temperature. A maximum of 3/5 tests can be carried out in one experiment. A rugged High Temperature Heater used with high grade thermal insulating blocks ensure a long life of the heater element even after continuous and repeated use at temperatures up-to 1520/1620 deg C.
- Automatic Image Recognition (AFT-2) Software for analysis of Ash Cones
- Automatic determination of (AFT-2) IT, DT, HT and FT of Ash Cones
- A highly sensitive and accurate controlling card controls the operation of the instrument and has advanced features like cold-junction compensation, temperature overshoot protection etc.
- The instrument can be programmed to take images of the Ash Cone at predetermined intervals of time or temperature
- The graph can be saved for future analysis.
- The results of ash graph can be printed out and the temperature rising curve can be displayed on the screen.
- A PCI Card fitted inside the instrument ensures seamless integration of the system with the computer.
- The software is designed to completely support Windows system.

FAQs of Ash Fusion Analyzer-AFT:
Q: How does the Ash Fusion Analyzer-AFT enhance accuracy during ash fusion tests?
A: The analyzer utilizes automatic and manual calibration, a high-resolution touch screen, and advanced image processing to ensure measurements of ash fusion temperatures are consistently accurate to within 1C.
Q: What is the process for conducting ash fusion analysis with this equipment?
A: Samples are placed into the up to five available test positions, and users select the desired atmosphere type (oxidizing, reducing, or inert). The heating rate is programmable up to 20C/min, and real-time observation is enabled through the integrated CCD camera, with results displayed and reported automatically.
Q: When should the oxidizing, reducing, or inert atmosphere control be used?
A: Atmosphere control is selected based on the specific coal or coke sample requirements and test standards. Oxidizing conditions are used for conventional ash fusion assessments, while reducing and inert environments are essential for research into alternate fusion behaviors.
Q: Where can the Ash Fusion Analyzer-AFT be installed for optimal performance?
A: Installation is recommended in laboratory environments with ambient temperatures between 10C and 40C and access to a 220-240 V AC power supply. The robust, corrosion-resistant construction allows placement in facilities handling coal and coke analysis.
Q: What are the benefits of integrated CCD camera and real-time observation?
A: The integrated camera system enables continuous monitoring of samples during heating cycles, helping detect physical changes at temperature transitions and capturing quality images for detailed documentation and reporting.
Q: How is data output and reporting handled by the Ash Fusion Analyzer-AFT?
A: Data and images are transferred via USB or Ethernet to connected PCs. Dedicated PC-based software provides customizable reports, advanced image analysis, and supports multiple languages for ease of use.
Q: What safety features are included with this analyzer?
A: Over-temperature protection, door interlock, and airflow monitoring are standard, minimizing risks to users and preserving the integrity of each sample throughout operation.
