新型阻化浆体抑制煤氧化性能试验研究

Research on Novel Retardant Slurry Performance to Restrain Coal Oxidized Spontaneous Combustion

为提高浆体防灭火性能,通过程序升温实验对一种新型阻化浆体抑制煤氧化自燃性能进行研究,将原煤样和经阻化浆体处理的煤样的实验结果进行对比,发现温度升高,阻化煤样耗氧量和CO生成量明显低于原煤样,煤炭自燃的热分解产物C2H4、C3H8的初始出现温度也得到提高,初始生成量降低。结果表明新型阻化浆体降低了煤的氧化速率,有效抑制了煤氧化自燃进程。

In order to improve the performance of slurry fire-fighting, uses a temperature-programmed experiment to study the performance of a novel retardant slurry which can control the coal oxidation. Comparing the experimental results of raw coal sample with the resistance of slurry , find that the temperature increases, the oxygen consumption and the production of CO are obviously lower than the raw coal sample, the initial temperature that results to the appearance of C2H4 and C3Hs is improved, and the initial production is reduced. The result shows that the novel retardant slurry can effectively inhibit the rate of coal oxidation and the oxidation process of coal.
