摘要:
基于Aspen Plus软件对林业废弃物氧气-水蒸气气化进行模拟计算,并对比模拟结果与试验结果以验证模型的可靠性,研究了气化温度、气化压力、当量比及水蒸气与废弃物的质量配比(S/F)对气化特性的影响.结果表明:随着温度升高气体产物中H2和CO含量增加,同时气化效率也相应增加,800 ℃时气化效率达到最高值为87.38%;压力增大时气体产物中H2,CO含量减少,但干气体产物的CH4含量及气体热值迅速增大;气化的最佳当量比约为0.22,过高或过低均会导致可燃组分和气化效率的下降;S/F增大时,气体产物中CO2,H2含量增多,CO含量减少,当S/F≥0.5时气化效率达到最大值并保持不变.
Abstract:
Aspen plus software was used to simulate the process of forestry residue oxygen-steam gasification. The model was validated by comparing simulation results with experimental ones. The effects of gasifier temperature, gasifier pressure, equivalence ratio and steam to forestry residue ratio(S/F)on gasification characteristics were investigated. Results show that rising temperature enhances the formation of H2 and CO and improves gasification efficiency to a maximum of 87.38% at 800 ℃. Increasing pressure lowers H2 and CO contents, but leads to rapid increase of CH4 content and gas heating value. The optimum equivalence ratio for oxygen-steam gasification is about 0.22. Higher or lower equivalence ratio can reduce the combustible components and the gasification efficiency. As the steam to forestry residue ratio goes up, the contents of H2 and CO increase while the content of CO2decreases. When S/F≥0.5, the gasification efficiency reaches a maximum and remains unchanged.
