摘要
The dynamic sulfur emission from combustion of blends of coal liquefaction residue(CLR) and biomass (sawdust, MX and leaves, SY) was studied in a tubular furnace. The results show that the curves of sulfur release in combustion of CLR or the blends gently increase with temperature, and the curves of sulfur release rate have two-peaks. Two sulfur release peaks are generated from different organic and inorganic sulfur forms in CLR and biomass. For the blends, the sulfur release is mainly determined by the high sulfur content of blends, which is CLR. With the decrease of CLR ratio, the amount of sulfur release and two maximum values of sulfur release rate derived from blends combustion all decrease, while the times for occurrence of the two characteristic peaks are both postponed.
