Pyrolysis technologies for municipal solid waste: A review

Pyrolysis has been examined as an attractive alternative to incineration for municipal solid waste (MSW) disposal that allows energy and resource recovery; however, it has seldom been applied independently with the output of pyrolysis products as end products. This review addresses the state-of-the-art of MSW pyrolysis in regards to its technologies and reactors, products and environmental impacts. In this review, first, the influence of important operating parameters such as final temperature, heating rate (HR) and residence time in the reaction zone on the pyrolysis behaviours and products is reviewed; then the pyrolysis technologies and reactors adopted in literatures and scale-up plants are evaluated. Third, the yields and main properties of the pyrolytic products from individual MSW components, refuse-derived fuel (RDF) made from MSW, and MSW are summarised. In the fourth section, in addition to emissions from pyrolysis processes, such as HCl, SO₂ and NH₃, contaminants in the products, including PCDD/F and heavy metals, are also reviewed, and available measures for improving the environmental impacts of pyrolysis are surveyed. It can be concluded that the single pyrolysis process is an effective waste-to-energy convertor but is not a guaranteed clean solution for MSW disposal. Based on this information, the prospects of applying pyrolysis technologies to dealing with MSW are evaluated and suggested.

雷管壳体安全检测过程的模拟与检测时间的确定

采用数值模拟与现场试验相结合的方法,分析了带缺陷雷管在气压检测过程中气体的泄漏过程,确定了最佳的检测时间。采用Fluent建立了缺陷雷管正气压检测模型,分析了缺陷在不同位置处的气体泄漏过程,研究了气体泄漏过程中,雷管内部气压的分布及其随时间变化过程,结果表明:距雷管顶端的缺陷因尺寸较大,所以该泄漏点的压强要大于侧壁处,而气体泄漏流速小于侧壁处,综合分析缺陷处和雷管内部的气体压降过程及试验,可确定4s为最佳的充气时间,5s作为最佳的雷管质量诊断时间。
