Why Proximate Analysis Is Done

Proximate analysis of a fuel provides the percentage of the material that burns in a gaseous state (volatile matter), in the solid state (fixed carbon), and the percentage of inorganic waste material (ash), and is therefore of fundamental importance for biomass energy use [37].

What is the proximate analysis?

Proximate analysis refers to the quantitative analysis of macromolecules in food. A combination of different techniques, such as extraction, Kjeldahl, NIR are used to determine protein, fat, moisture, ash and carbohydrates levels.

What are the uses of proximate and ultimate analysis?

The key difference between proximate and ultimate analysis of coal is that proximate analysis is the technique used to analyze the moisture content, ash content and fixed carbon of coal whereas ultimate analysis is the technique used to analyze the chemical composition of coal.
