摘要/Abstract

摘要： Ignition-assisting agents for densified corn stover briquette fuel (DCBF) were developed, and their ignition and emission characteristics were investigated using type LLA-6 household cooking stove. Three waste liquid fuels, waste engine oil (E), diesel oil (D), and industrial alcohol (A), were used as raw materials to make 25 ignition- assisting agents by mixing at different ratios. Their ignition performance was evaluated in terms of ignition time and cost. It was found that ignition-assisting agents ED15 (a mix of E and D at volume ratio of 1︰5) and DA51 (a mix of D and A at volume ratio of 5︰1) presented better ignition results with shorter ignition time (40-53 s) and lower cost (6.1 and 5.3 cents) at the dosages of 9 ml and 8 ml, respectively. The emission of O2, CO, CO2, NOx, and SO2, the temperature in fume gas, and combustion efficiency were investigated for ED15 and DA51. The results show that the emission of ED15 with the dosage of 9 ml is lower than that of DA51 with the dosage of 8 ml in the ignition process. ED15 at the dosage of 9 ml achieves satisfactory combustion efficiency and emits less pollutant, so it is recommended for practical application. The study will provide a cost-effective and environmentally friendly approach to fast ignite DCBF and break the barrier to the prac-tical application of DCBF.
