化学分离法分析大型纸浆发电厂废渣中生物质底灰和飞灰成分(英文)

采用三步分离法,其中第一步用水,第二步用乙酸铵,第三步用盐酸,提取纸浆发电厂生物质飞灰和底灰的组分,以评估这些残渣的浸出行为。除了Mo、S、Na以及那些浓度低于检测范围的元素外,在这两种灰份中,对于其他元素这三种浸出剂的浸出能力从弱到强的顺序为:水、乙酸铵和盐酸。采用三步分离法处理的废渣中元素浓度比前期用BCR连续提取法得到的低。     

煤粉与废塑料混合在模拟高炉风温下的燃烧试验研究

为了研究向高炉中混合喷吹废塑料和煤粉的可行性,在模拟高炉喷吹风温条件下改变空气流量、混合试样中的废塑料颗粒粒径和混合掺入废塑料比例进行燃烧性能(平均燃烧速率)研究。结果表明:空气流量对燃烧平均速率的影响最为显著,其次是塑料比例,塑料粒度对混合试样燃烧平均速率的影响最小;在高温燃烧下废塑料所产生的灰烬量低于煤粉。     

SZ36-1油田污水悬浮物无机组分研究

综合利用扫描电镜能谱分析、X-射线衍射仪等先进仪器对SZ36-1油田滤膜组分燃烧前后进行综合分析研究。通过分析无机组分中Fe、Ca等元素的变化规律,并结合现场水质监测数据,研究发现SZ36-1油田回注污水由CEP向AJ、平台输送过程中水质逐级恶化;同时污水由CEP到A平台再到J平台过程中,Fe原子百分比平均值依次为4.45%、13.03%、19.45%,Ca原子百分比平均值依次为4.33%、5.43%、5.66%。腐蚀、结垢现象逐渐加剧,是导致注水水质恶化的主要原因。     

时间灰烬里的上海往事

妖娆的旗袍、逼仄的弄堂、咿呀绵软的吴语，遥远年代的老歌、身份含糊的人、晦涩纠缠的情感……时光的褶皱被一一抚平，遥远时代消逝的流年勾勒出时间灰烬里的上海往事。     

火袭花都

3月23日早上7点，杭州市区石桥路上的花都市场内，店主们纷纷打开卷闸门，开始一天忙碌的营业。他们没有想到的是，两小时后的一把大火，点燃了梦魇时刻。火势顷刻间蔓延，直逼间间相连的18间店铺，市场上空很快被浓烟包围。不少店主只能眼睁睁看着货物一瞬间消失在火海中，随即被烧成灰烬。     

THE STUDY OF THE BASIC THEORY AND THE APPLICATION OF REMOVAL PYRITE AND ASH FROM FINE COAL WITH ELECTROSTATIC SEPARATOR

The effect of removing pyrite and ash from fine coal with electrostatic separator is determined by the electric property of coal, the distribution of corona ion and electrostatic field, and the disperse and even feed. The dielectric constant of coal and mineral matter is studied in this paper and the amendment has been made to survey theory. The oscillogram is adopted to study the distribution of corona ion and electrostatic field. The paper details the study of remoing pyrite and ash from fine coal, and the test results demonstrate the high efficiency of removing pyrite and ash with electrostatic separator.     

浴火再生

凤凰是再生的象征，那美丽的形态被赋予了极其深邃的涵义，似乎生命轮回成为一种值古的美丽，每经历五百年，凤凰要自焚一回，它要烧掉它衰老的和瘦弱的外形，于是一只崭新的，朝气蓬勃的和脱胎换骨的凤凰就从灰烬中飞出。     

时间的灰烬

看到这个题目，你会想起什么，仅仅是“Ashes of Time”么？其实这是一部我很喜欢的王家卫的电影——《东邪西毒》。这也是少数几部被外国人翻译的比较象样的电影名字（那些外国人总是依着性子，胡乱的编）。不知道为什么要选这样一部电影的名字来作为我文章的题目，但是它确实让我感受到了那种温暖而又潮湿的流动，时间就像被风吹起的细沙，“等待”让它堆积成了沙漠，无边无际……     

The Mineral Transformation of Huainan Coal Ashes in Reducing Atmospheres

By using the advanced instrumentation of a Computer Controlled Scanning Electron Microscope （CCSEM）, X-ray diffraction （XRD） and X-ray fluorescence （XRF）, the ash composition and the mineral components of six typical Huainan coals of different origins were studied. The transformation of mineral matter at high temperatures was tracked by XRD in reducing conditions. The quartz phase decreased sharply and the anorthite content tended to increase at first and then decreased with increasing temperatures. The formed mullite phase reached a maximum at 1250 ℃ but showed a tendency of slow decline when the temperature was over 1250 ℃. The mullite formed in the heating process was the main reason of the high ash melting temperature of Huainan coals. Differences in peak intensity of mullite and anorthite reflected differences in phase concentration of the quenched slag fractions, which contributed to the differences in ash melting temperatures. The differences in the location of an mnorphous hump maximum indicated differences of glass types which may affect ash melting temperatures. For Huainan coal samples with relatively high ash melting tempera- tures, the intensity of the diffraction lines for mullite under reducing condition is high while for the samples with relatively low ash melting temperature the intensity for anorthite is high.     

扫描电镜能谱辨识纸质材料燃烧灰烬的研究

利用扫描电镜能谱仪,分析了常见纸质材料——静电复印纸、纸巾纸、报纸和瓦楞纸板等燃烧后灰烬颗粒的形貌特征、成分及组成比例,分析了水分、温度对灰烬颗粒形貌的影响。结果表明,以上4种纸质材料的灰烬颗粒形貌明显不同。静电复印纸灰烬颗粒外形单一,钙元素含量远高于其他元素;纸巾纸灰烬中纤维体边沿上有呈圆点状或细条状元机物;报纸灰烬中纤维状物质形多样;瓦楞纸板灰烬中含有较多的奇特形状颗粒,且氮元素含量高。
