Ash content analysis

Ash content analysis measures the total mineral and inorganic residue remaining after a sample, such as coal or biomass, is burned at high temperatures. This residue, called ash, indicates the amount of inorganic material present. The test helps assess the fuel’s purity and energy content, as higher ash levels generally mean less efficient combustion and potential handling issues. The process involves burning a known sample in a controlled environment and weighing the remaining ash to calculate its percentage relative to the original sample. This information is valuable for evaluating fuel quality and suitability for various energy applications.
