煤質活性炭著火點的測定方法

发布时间：2015-10-26 点击次数：2376次

煤炭活性炭的着火点试验方法的原理，在空气流中按一定升温速率加热试料，随着温度的上升，炭样温度突然上升超过进入炭层空气的温度，此时的温度即为着火点。

活性炭着火点试验条件：

干燥、洁净、无油的空气源-----空气应通过空气过滤器和干燥器，空气的相对湿度在25℃ 下应小于5%。

活性炭的试验的制备：

对所送样品用四分法取出约35ml试样，将试样放入试验筛中，按GB/T7702.2的规定，除去试样中的炭粉，备用。

HTRD-6M型煤顆粒活性炭著火點測定步驟“：

1、將試樣填充石英灼管。

2、碳層高度25mm±1mm ，炭層上部應覆蓋厚度爲15mm石英珠、熱電偶尖端置于試料上端四分之三處，另一端熱電偶尖端置于炭層下端四分之三處，用于升溫速率控制。

3、通入幹燥、潔淨、無油的空氣，以20L/mm的流量吹試料1h

4、將空氣流量調至14.7L/min± 0.3L/min

5、調節程序升溫器，使通往炭樣的空氣流溫度以大約10℃ /min的速率升溫，當空氣溫度達到約150℃ 時，改變升溫速率至2℃ /min-3℃ /min

6、保持2℃ /min-3℃ /min的升溫速率，直至熱電偶T1或T2測得的炭層溫度突然升高至著火。

7、發生著火時，立刻切斷空氣流並通入氮氣滅火。

结果计算：根据自动平衡记录的热电偶T1或T2绘制的温度时间关系曲线，在着火前后的温度曲线画切线，切线交点所对应的温度值即为着火点。

The great ship steamed onward, day after day and night after night. There was no storm to break the monotony; no sail showed itself on the horizon; no one left the steamer, and no new-comers appeared; nobody saw fit to quarrel with any one else; and there was not a passenger who showed a disposition to quarrel with his surroundings. Stories were told and songs were sung, to while away the time; and, finally, on the twentieth day, the captain announced that they were approaching land, and the voyage would soon be over. "I could go on with a long account of the tortures in China, but they are not very pleasant reading, and, besides, some of them are too horrible for belief. I will stop with the torture known as 'the hot-water snake,' which consists of a coil of thin tubing of tin or pewter in the form of a serpent. One of these coils is twisted around each arm of the victim, and another around his body, in such a way that the head of the snake is higher than any other part. Then they pour boiling water into the mouth of the snake, and the flesh of the prisoner is burned and scalded in the most terrible manner. This punishment is said to be used rarely, and only[Pg 374] on persons accused of crimes against the government. It is too horrible to be popular, even among the most cold-blooded people in the world. "No, Lieutenant, she nearly cried. Oh, I wish we were on some dangerous errand to-night, instead of just camp and bed!" One glance at the dim mirror and Leona Lalage flew down the corridor. The music of the band was like the sound of mocking demons in her ears. As she flew up the stairs she could see the blank windows of the Corner House staring dreadfully in. Then she locked the door behind her and flung herself headlong down on the bed. . . . Surely they were a long time getting that hot water. In such a case as this hurry was everything. Bruce crept from the room and looked over the banisters. The whole place was in darkness! "Just a moment," Leona said eagerly. "Suppose I deny that. How are you going to prove that I did so?" It was weary work sitting there and pretending to drink, but patience has its reward at last. Gradually the shy swindlers became accustomed to the seedy shop assistant, who even went out of his way to give them hints as to credulous firms. It seemed to Prout that he knew all the gang at last save one. 162 "I told you to go," she repeated, raising her brows. "Come here, Shorty, you dirty little rascal," said the Deacon, assuming a severely maternal tone, at which Si laughed feebly but cheerily, "and let me wash your face and comb your hair." a-courtin', as you will know if ever you was a widower, and he "Could the gunner knock a man's head off, or one of his legs, just as he pleased?" "But—" "You can't go by yourself—he wudn't like it." "Not if we stick to the farm. Did you notice that ring on his little finger?" "Can't you mortgage?" HoME 色色新妈妈电影 ENTER NUMBET 0010cll160805.com.cn
