The co-firing of bituminous coal with woody biomass provided an available approach for cutting carbon emissions. In this work, a study on the application of high blending ratios of biomass with coal in co-firing was experimentally conducted in a lab-scale drop tube furnace (DTF) to reduce CO 2 emissions and control deposition and …Web

The coal nozzle comprises a duplex tube; the pulverised coal. CO 2 reduction by ammonia co-firing. Since ammonia is a carbon-free gas, CO 2 emissions should decrease in proportion to the increase of co-firing rate. Fig. 3 shows the results obtained, when ammonia is co-fired with pulverised coal. Ammonia supply points are …Web
