Introduction
When it comes to understanding the combustion properties of fuels like coal, coke, and biomass, one of the most critical parameters is volatile matter. It determines how a fuel behaves when heated and directly influences its combustion efficiency and performance. The Volatile Matter Furnace – VMF/ASTM is specifically designed to measure this parameter with accuracy, speed, and repeatability — making it an essential instrument in any coal and coke testing laboratory.
The VMF/ASTM furnace provides a standardized and reliable way to determine the volatile matter content as per ASTM D3175, ensuring that results are consistent and comparable across industries and laboratories.

What Is Volatile Matter and Why It Matters
Volatile matter refers to the gaseous products (excluding moisture) released when a fuel is heated in the absence of air. These gases include hydrocarbons, carbon monoxide, hydrogen, and other compounds that vaporize before combustion.
The percentage of volatile matter in a fuel determines how it will burn:
- Fuels with high volatile matter ignite easily but may burn less efficiently.
- Fuels with low volatile matter burn slowly and may require higher ignition temperatures.
Hence, measuring volatile matter is essential for:
- Classifying coal grades
- Assessing combustion characteristics
- Evaluating coking properties
- Optimizing furnace and boiler performance
That’s where the Volatile Matter Furnace – VMF/ASTM proves indispensable — providing accurate data that supports energy efficiency and fuel quality optimization.
What Is a Volatile Matter Furnace?
A Volatile Matter Furnace is a high-temperature laboratory instrument designed to determine the volatile matter content of coal, coke, and similar solid fuels. It operates under precisely controlled temperature and time conditions to simulate the heating process and measure the mass loss associated with volatile release.
The VMF/ASTM model is built to meet the rigorous specifications of ASTM D3175, ensuring full compliance and reliability for professional laboratories. It provides fast, accurate, and reproducible measurements essential for research, production, and quality control environments.
