Ignition of a group of the woody biomass particles. (1st October 2021) - Syrodoy, S.V.
Graphical abstract: Highlights: The ignition rate of a group of biomass particles depends on their concentration in a unit volume. The ignition mechanism of a group of biomass particles depends on their location relative to each other. In a group of several particles of wood are ignited, usually located in the upper rows. Abstract: The results of the experimental studies of the ignition of a group of the woody biomass particles of a cubic form under conditions corresponding to the combustion chambers of the boiler units have been presented. The influence of the number of the particles in the group and their position relative to each other on the characteristics and conditions of ignition has been established. The results of the experiments show that an increase in the concentration of the particles per unit volume leads to an acceleration of their ignition process. When a group of the particles is ignited, the particles that are located at the outer boundary of the group ignite first. It was found that the ignition of each subsequent particle from a combination of four or more occurs with a delay in relation to the previous one not more than 0.1 s.
