Sample Preparation and the Analysis of Secondary and Biogenic Fuels

Sample Preparation and the Analysis of Secondary and Biogenic Fuels

Secondary and biogenic fuels are usually inhomogeneous and come in large volumes. For reliable analysis results, laboratories require part samples which are fully representative of the original sample. These need to be sub-divided and homogenized before they can be submitted to analysis. Ideally, the preparation of the analytical sample should not take too much time. The homogenization of the sub-divided part-sample is typically done in two steps – preliminary grinding and pulverization. The homogenized sample must represent the original lab sample, but also the much larger initial amount.

Once the sample is prepared, it can be analyzed, for example for its calorific value. The effective calorific value of fuels depends on the respective carbon and especially hydrogen content. When secondary fuels are combusted, for example, a significant amount of water is formed from the hydrogen content which must then be vaporized through a rotary tube furnace. This procedure significantly reduces the calorific value. Elemental analysis and the reliable determination of carbon, hydrogen and sulfur content is therefore an essential part of the quality control process.

In this webinar you will learn more about:

  • Correct sampling and sample division
  • Homogenization and how to select the most suitable mill
  • Application examples
  • Particle size determination with sieving machines
  • Analysis of Carbon, Hydrogen and Sulfur concentrations
