Coal & Cokes

TLR International Laboratories has several units for analysing solid (bio) fuels. The laboratory not only has state-of-the-art equipment, it also has extensive experience with methods of this type.

 

Proximate and ultimate analyses are important for determining the type and quality of coal and cokes. In the proximate analyses, we look at the moisture content, ash, volatile components and the calorific value. In ultimate analyses, the elemental composition of hydrogen, carbon, sulphur, nitrogen and oxygen is determined.

 

In addition, TLR has methods for analysing the ash, both in terms of composition and fusion temperature. Physical analysis methods are also available, including grindability and swelling. The measurements for these are Hardgrove Grindability Index (HGI) and the Free Swelling Index (SFI).
