Co-Combustion of Coal and Biomass: Heating Surface Slagging and Flue Gases

Fire, Journal Year: 2025, Volume and Issue: 8(3), P. 106 - 106

An experimental study was carried out on the ignition and combustion processes of particles (100–200 µm in size) coals different degrees metamorphism biomass, as well mixtures based them, under conditions conductive convective heating, which correspond to fuel boiler furnaces at grates flaring combustion. The biomass contents composition coal-based were 10, 20, 30 wt.%. Under (at 700–1000 °C) 500–800 heating particles, delay times determined using a hardware–software complex for high-speed video registration fast processes. found vary from 1 12.2 s 0.01 0.19 heating. addition 10–30 wt.% reduced by up 70%. analysis flue gas during solid fuels allowed us establish concentrations main anthropogenic emissions. use an additive (from 10 230 wt.%) coal NOx SOx emissions 19–42% 24–39%, respectively. propensity cause slagging depending their component established. mixture did not affect increase tendency surfaces furnace pose threat layer agglomeration mixtures.
