“…The processing of coal with biomass, according to several studies [23,24], was found to result in significant reducing in sulfur and nitrogen oxide emissions-by up to 1.5-2 times [25,26]. This effect is applied at various thermal power plants in different countries where up to 13 wt.% of agricultural wastes [27] or biomass of other types [28][29][30][31] is co-burned with coal, but so far, such a sufficiently effective solution to the environmental problems created by coal-fired thermal power plants [32] is not theoretically justified. There are reliable experimental data [33,34] and the results of their industrial application, but there is no theory that justifies the laws of physical and chemical processes that occur during the sequestration of sulfur and nitrogen oxides in the conditions of co-combustion of coal and biomass.…”

On the Effect of the Distances between Coal and Wood Particles during Their Joint Pyrolysis on Sulfur Oxides Formation

The simultaneous pyrolysis of coal with wood was experimentally found to allow reducing concentrations of sulfur-containing substances in gases released. The objective of experimental studies is comparison of the sulphate of calcium and aluminum in the ash of coal-wood mixtures after pyrolysis of the latter in a dense “packing” of aggregate particles of these two fuels and at a few millimeters distance between particles. The 3B-grade lignite, T-grade bituminous coal and pinewood sawmill waste were chosen as feedstocks for pyrolysis experiments because they are widespread in Russia as well as many other countries. The elemental composition of all raw materials and pyrolysis residues was determined. The inorganic composition of obtained pyrolysis product in the solid phase was characterized by X-ray analysis. The content of aluminum and calcium sulfate in residue in case of simultaneous processing of coal with wood was found to be higher, compared to the processing of coal only (within the random errors of the experiment), than those established for such mixtures under conditions of dense “packing” of large masses (up to 15 g).
