Experimental study of pine sawdust ignition in a vertical tube furnace

The combustion processes of composite particles of powdered fuel from lignocellulose and coal have not been previously studied. It is planned that a non-obvious relationship will be established between the structure and properties of solid fuels obtained under various conditions of preliminary machining of individual fuel components and joint mechanochemical processing of fuel components before burning in the combustion chamber. Based on the data obtained, the description of both individual chemical and physical processes and complex mathematical models will be improved. In this paper, we investigate the influence of the structure and dimensions of a particles pine sawdust as one of the components of composite fuel on ignition and thermal decomposition.
