利用热空气加热的方法对不同含水量褐煤煤样的强制氧化着火特性进行实验研究。通过对不同含水量褐煤煤样在不同温度条件下的升温进程、气体产生率以及耗氧量的分析，得出了在本实验条件下含水量对强制氧化着火特性的影响规律。研究表明：在本实验条件下，含水量较低的煤样着火时间更长，较大含水量对褐煤升温进程有一定的促进作用；在适当的含水量范围内，煤样的含水量越高，CO、CO2的产生率越大；含水量在19．5％～23．5％（质量分数）时，含水量越小，耗氧量越大。

The forced oxidation and ignition characteristics of lignite samples with different moisture content was investigated by the hot air heating method.The influence rules of moisture content on lignite forced oxidation and ignition characteristics were obtained by the analysis of temperature rising process,gas production rate and oxygen consumption.It is found that the lower moisture content of coal sample,the longer ignition time under this experimental condition,and the high moisture content in lig-nite can be active to heating process.In the proper range of moisture content,the higher moisture content it has,the bigger pro-duction rate of CO and CO2 it gets.When the moisture content is between 19.5% and 23.5% (mass fraction),the lower mois-ture content it has,the more oxygen consumption it gets.
