XDHR-5 ash melting point tester

The melting characteristics of coal ash are directly related to the slagging (commonly known as coking) and its severity in power plant boilers, thus it has a great impact on the safety and economic operation of boilers. This instrument is an intelligent device specifically designed for measuring the fusibility of coal ash. According to the national standard GB/T 219-2008, the heating speed is automatically controlled by a microcomputer, and the furnace body can rotate freely, making it easy to take and lay out.

Performance characteristics of XDHR-5 microcomputer ash melting tester

1. Microcomputer automatic control, in compliance with national standards and GB/T 219-2008 requirements. Suitable for measuring the ash melting characteristics of coal.

2. Real time display of gray cone image changes, automatic storage, and easy reading.

3. Automatically determine four characteristic temperatures; It can also be manually judged or compared through image playback for further verification and analysis.

4. Adopting a high-definition camera, the gray cone image is clear and intuitive; Ultra fine thermocouple design eliminates image interference.

5. The screen displays the temperature rise curve, and you can choose to print the gray cone image results and related data.

6. Using RS232 serial communication, it can be connected to the internet online. Integrated structural design, beautiful and practical, easy to maintain.

7. Microcomputer program control, automatically completes the heating process of ash melting point determination according to national standards.

8. It has multiple fault prompt functions. Easy to operate, stable and reliable performance.

9. There are 1-3 samples, and the microcomputer screen automatically displays the gray cone image and prints images of 4 temperature points.

The experimental process of the microcomputer ash melting point tester is monitored and controlled by a camera system and a computer system. The computer automatically determines the characteristic melting temperature, deformation (DT), softening (ST), hemisphere temperature (HT), and flow temperature (FT) based on real-time images of the heating changes of the ash cone. Automatically store and display the entire experimental process, the furnace body can rotate freely, and it is easy to take and place.
