摘　　要：文章从实验测试和数值模拟两方面对生物质燃气自燃温度(AIT)的相关研究进行了综述。回顾了燃气AIT的实验测试装置,对比不同压力下测试方法和着火判据的异同;对零维、二维和三维数值模拟方法进行了介绍。不同的测试方法对生物质各组分的测试结果差异很大,温度的最大波动达到210℃;一般着火等待时间以10 min为宜;稳态和非稳态的雷诺平均(RANS)可以初步模拟AIT,S曲线可以应用于新型燃烧模式的AIT预测。多组分混合气的标准化测试将成为未来发展趋势。文章旨在为生物质燃气应用的标准制定提供技术参考。In this paper,the experimental and numerical methods of determining the auto-ignition temperature(AIT)of biomass gas in recent years are reviewed.The experimental devices for AIT testing are briefly described,and the testing methods and ignition criteria under different pressures are analyzed comparatively.0D,2D,and 3D numerical calculation methods are summarized.The study shows that the test results of various components of biomass gas varied greatly with a maximum fluctuation of 210℃.Generally,the ignition waiting time should be 10 min.The steady and unsteady Reynolds average(RANS)can initially simulate the AIT,and the S curve can be applied to the AIT prediction for the new combustion mode.The standardized testing of the multicomponent mixture will become the future trend.This study aims to provide technical references for the standard of biomass gas application.
