  分析了半焦种类、实验总压、氧浓度、试样粒径和加热速率对最大失重速率、最大失重峰温、燃烧时间、燃烬温度等的影响。
• Coal - char pyrolysis , firing , burnt and limestone calcination under o _ ( 2 ) / n _ ( 2 ) oro _ ( 2 ) / co _ ( 2 ) atmosphere were carried on a thermobalance . limestone calcination and sulfuration under o _ ( 2 ) / co _ ( 2 ) atmosphere were tested on a bench scale fluidized bed facility . the characteristics of coal combustion and pollutant emission under o _ ( 2 ) / n _ ( 2 ) or o _ ( 2 ) / co _ ( 2 ) atmosphere were experimented on a circulating fluidized bed multi - function test - facility
  在热天平上进行o _ 2 / n _ 2气氛与o _ 2 / co _ 2气氛下的煤焦热解、着火与燃烬反应动力学及石灰石煅烧分解特性研究；在小型流化床试验台上进行石灰石在o _ 2 / co _ 2气氛下的煅烧与硫化反应特性研究；在设计、搭建的循环流化床多功能综合试验台上进行o _ 2 / n _ 2气氛与o _ 2 / co _ 2气氛下的煤燃烧特性与污染物排放规律研究。
• In order to solve the problems effectively , under the auspices of 863 plan in china , the synthesis diagnosis has been carried by means of measuring and numerical imitating the combustion chamber of refining column , and some conclusions is such as : ( 1 ) through measuring the temperature and combustion in the burning chamber of the refining column , the result shows the temperature difference on the same level is more than that in height direction , and there is a few of co in bottom of burning chamber . ( 2 ) in order to ensure normal work of flue system in lead column in the course of zinc refining , theoretic calculation and measure about the flow resistance of exhaust gas are carried through . the results of study reveal that drawing out force of chimney is inadequate , which is mainly caused by illogicality of flue construction
  在研究过程中，采取了现场实测和数值仿真手段对韶关冶炼厂锌精馏铅塔燃烧室及排烟系统进行了综合诊断，具体结果包括如下： ( 1 )完成锌精馏铅塔燃烧室内温度测试以及燃烧状况的测试，结果发现：铅塔燃烧室内水平方向的烟气温度并非均匀，而且其温差比上下方向的温差更大，以及铅塔燃烧室尾部存在co未燃烬问题； ( 2 )为了保证铅塔烟气系统的正常工作，对烟道系统的阻力进行了理论计算及测试分析，结果发现：锌精馏铅塔烟气系统中烟囱抽力不够，这主要是烟道结构不合理所造成的。
• Instead , stardust investigator don brownlee of the university of washington in seattle and his colleagues found that the isotopic composition of nearly every grain that they analyzed matched that of the inner solar system , demonstrating that the rocky material in wild 2 indeed originated in the solar system
  与猜测相反，位于西雅图的华盛顿大学的星尘研究员唐?布朗里和他的同事发现他们分析的几乎每一粒星尘的同位素组成与内层太阳系的尘烬相同，这说明维尔德2上的岩石物质确实源自于太阳系。
• Using this system , research on nox emission and burnout characters of the test facility are carried out . the results of influence on nox emission and carbon in fly ash by coal type , coal particle diameter , furnace temperature and excess air are reached through tests . then micronized coal reburning tests are processed , which show a remarkable effect results on nox reduction and burnout rate
  通过大量的试验，得出了煤种、煤粉细度、炉膛温度和过量空气系数等因素对nox排放和煤粉燃烬率的影响趋势；并在此基础上研究了超细粉再燃对脱氮效果和燃烬性能的作用，试验结果表明超细煤粉再燃对降低nox排放和飞灰含碳量具有明显的效果。
