Quantification of the calorific value in solids and liquids. Calorific value indicates the amount of energy contained in a unit of mass, and is usually expressed in Kcal/g. A analysis It is carried out in a calorimetric bomb, with automatic oxygen injection and water circulation. The analyses, in the case of solid fuels, can also be combined with the determination of volatile material, ash content and fixed carbon content. It can be applied to fuels in general, biofuels, biomass, food and animal feed.
