【摘要】：實(shí)驗(yàn)采用ZRJ-1型煤自燃傾向測(cè)定儀,分別對(duì)不同煤樣進(jìn)行不同溫度下吸附氧氣后的脫附實(shí)驗(yàn)。實(shí)驗(yàn)得出脫附過(guò)程中的氧氣的狀態(tài)變化過(guò)程特征曲線,曲線斜率隨脫附出的氧氣濃度變化而變化。整體表現(xiàn)為2個(gè)波峰,其中后1個(gè)波峰表現(xiàn)為拖尾峰。不同溫度下的煤的物理吸氧量變化規(guī)律為隨著溫度的升高物理吸氧量呈整體下降趨勢(shì),在一定溫度范圍內(nèi)有波動(dòng)。
[Abstract]:The desorption experiments of oxygen adsorption on different coal samples at different temperatures were carried out with ZRJ- 1 type coal spontaneous combustion propensity tester. The characteristic curve of the state change of oxygen during desorption is obtained, and the slope of the curve varies with the change of oxygen concentration. As a whole, there were 2 peaks, and the last one was a trailing peak. The variation rule of physical oxygen uptake of coal at different temperatures is that the physical oxygen uptake of coal decreases with the increase of temperature and fluctuates in a certain temperature range.
