The outhor selected fine coal dry cleaning using high —tension separator as the research subject of doctorial thesis.

作者选择了应用高压静电选进行徽粉煤干法脱硫降灰的研究作为博士学位论文的研究课题。

Ng inside the gasifier and the advantages and disadvantages of the the gasifier were detailedly analyzed; at the same time realization conditions, formation mechanism and implementation approaches of flameless oxidation technology also be explored in detail.

由此设计了一种新型干煤粉气流床气化炉，论证了高灰熔点煤在该气化炉上实现高效气化和液态排渣的可行性进。

And do the slagging characteristic research on CWS used in Test.

通过多种结渣预测模型，对所使用的注汽锅炉所用的水煤浆及其灰渣，进行了结渣特性进行了研究；对锅炉改造和所用的燃烧器的进行了系统的试验和计算，对炉内的飞灰轨迹进行了模拟以研究炉内可能产生的积灰与结渣。

An effective approach for utilizing low grade coals,fluidized bed combustion with flyash underbed recycle is recommended based on analyzing the state of the art of fluidized bed combustion.

针对国内外流化床燃烧技术发展现状，提出了飞灰循环底饲回燃利用劣质煤的有效途径。

The combustion technology of CFB boiler as a low pollution technology has been pained attention to, and has been widespread application, but many questions in operation need to solved, for example: air-flow control, automatic combustion control,scarifying, coal-feed system,high carbon content in fly ash ect.

2006中国电机工程学会年会，河南郑州，中国电机工程学会循环流化床锅炉燃烧技术作为一种低污染清洁燃烧技术受到重视，得到广泛应用，但是运行中暴露出不少问题亟得解决，如锅炉风量控制、出力调整、结焦、给煤系统、飞灰可燃物高等问题。

The higher carbon content in dry, ash-free basis of coal shows more remarkable influence of particle size on specific surface area, porosity ratio and pore volume.

煤中无水无灰基元素碳含量越高则其比表面积、孔隙容积与空隙面积受颗粒粒度的影响也就越大。

The research show that from anthracite, lean coal to bituminous, reaction rate become more and more large and ignition activation energy become more and more small; ignition activation energy falls and reaction rate increases as the volatile content increases;With the carbon content of dry ash-free basis increasing, ignition activation energy increases and reaction rate falls.

结果表明：从无烟煤，贫煤到烟煤，其反应速率越来越大，频率因子越来越小，着火活化能越来越低；挥发分增加，活化能减小，反应速率变大；干燥无灰基固定碳含量增加，着火活化能增加，反应速率减小。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
