charcoal

The values of the highest heat of combustion for the dry ashless state of combustion of 35 samples of vegetable raw materials and 35 charcoal were determined. The need for calculating indicators of their technical and elemental analysis was established. Mathematical and graphical relationships between the actual and estimated values of the highest heat of combustion of plant raw materials for the production of biogas and charcoal were developed. A statistical analysis of the dependence data was performed.

The use of charcoal (CC) for various industries was analysed; the modern ideas about the factors influencing the process of obtaining CC were considered. The effect of raw materials nature (wood or agricultural wastes) and their characteristics (size, physical properties, chemical composition), as well as carbonization temperature, heating rate, oxygen level and pressure on the yield and quality of CC was described.
