Fossil Energies as studied by Thermal Analysis

The study of fossil fuels by thermal analysis can yield valuable information. For example thermal gravimetric analysis (TGA) can be used for proximate analysis of coal.

Analysis of Coal by Pressed Pellets

Coal is the most abundant source of energy amongst the remaining fossil fuels in the world. Coal production is classified into two groups based on its usage. Thermal (steam) coal is used for generation of electricity, whereas metallurgical (coking) coal is mainly used for production of steel. Coal beneficiation (coal cleaning) is critical since it determines the quality of final product. Rapid and accurate elemental determination is therefore important in order to assure that harmful components to the environment such as ash and sulfur are sufficiently low. X-ray fluorescence (XRF) spectrometry with pressed powder method is a simple analysis technique that can rapidly determine elemental composition of coal with high accuracy and precision. It is therefore well suited for industrial process and quality control. This non-destructive analytical technique has the added benefit of easily being able to determine the concentration of elements that can be lost during ashing process. This note demonstrates rapid and accurate determination for multiple elements in whole coal by pressed powder method.

Calorific value determination of coal, coke and oil sources for power generation.

Calorific value determination of coal, coke and oil sources for power generation. Any powerstation that is burning coal, coke, oil, or SRD and RDF must know it’s energy value for deterining power generation. Parr calorimeters are a crucial tool for every day use for the analysis labs associated with power generation.
