Abstract
The results of experimental studies of the influence of the initial moisture content of cedar needles on the time characteristics of ignition of coal-water suspensions based on D-grade thermal coal are presented. Biomass (fallen and freshly cut cedar needles) was used as an additive accelerating the ignition process. An analysis was carried out of the influence of the initial moisture content of the plant additive in the composition of water-soluble suspensions on the ignition delay times. It has been established that the initial moisture content of cedar needles does not have a significant effect on the time characteristics of the fuel ignition process (the difference does not exceed 4%), but the addition of needles leads to a significant reduction in the ignition delay times (the VUS ignites faster on average by 15%).
