NO_x decreasing ratio of micronized coal reburning comparing withgeneral combustion is not proportionable to NO_x reduction ratio in reduction zone,which depends on both NO_x reduction ratio and NO_x increment in burnout zone.

超细粉再燃与常规燃烧相比NO_x脱除率与再燃区NO_x还原率不成正比，它是由NO_x还原率与燃尽区NO_x新的生成综合决定的。

In this work, Large Eddy Simulation and standard k-εturbulence model were employed separately to simulate a round and a elliptic turbulent jet in cross flow with the Reynold number of 16600. The numerical results of the trajectory show a good agreement with the previous experimental data.

在空气分级和煤粉再燃技术中，OFA射流和再燃射流的穿透深度，以及与主烟气之间的混合扩散情况是脱硝率的重要影响因素，对这两股射流的流动规律进行研究是很有必要的，OFA射流和再燃射流都属于典型的横流中的射流(JICF：jet in cross flow)。

An increase in valve overlap results in some recycling of unburnt fuel which reduces unburnt hydrocarbons and also results in internal exhaust gas recirculation, further reducing nitrogen oxides.

在阀门增加重叠部分未燃尽的燃料可以减少未燃尽碳氢化合物，并在内部废气再循环的成果，进一步降低了氮氧化物回收的结果。

A Corner-tangential-boiler of 410t/h in Guohua Beijing thermal powerplant was studied in the thesis. Firstly, optimizing operation was carried on boiler for de-NOx emission; secondly, numerical simulation was made by Fluent software, the calculation results were consistent with experiments. The retrofit scheme of reburn was put out which ascended the upper primary wind.

本论文以国华北京热电分公司410t／h四角切圆燃煤锅炉为研究对象，首先进行了锅炉低NOx优化运行的试验研究；并通过Fluent数值模拟对其进行了深入的研究，计算结果与实际情况吻合较好，同时提出将上一次风上移作为再燃的改造方案，并对改造后的情况进行模拟预测，得到改造后工况运行优于现行工况。

At the same time the carton content of fly ash and slag condition of boiler were almost not influenced by coal water slurry technology applied. These show coal water slurry rebuing technology applied in large scale station boiler is a prospect method and offer instruct for the practical utilization of coal water slurry reburning.

同时试验结果表明采用水煤浆再燃技术时对炉内结渣状况和飞灰含碳量的影响很小，说明大型电站锅炉上采用水煤浆再燃是一种有前景的脱硝方法，这对水煤浆再燃技术的推广应用具有重要意义。

Based on it,three dimensional numerical simulation of Natural Gas Rebuming is carried out.With the typical tangentially fired boilers in China as research object,it is set up that the pulverized coal combustion models and the NOx models.Through CFD method,the combustion process is simulated.All of these will promote the engineering applications of fuel reburning technology.

在此基础上，对燃煤锅炉的天然气再燃过程进行了系统的三维数值模拟，以我国典型的四角切圆煤粉锅炉为研究对象，建立了煤粉扩散燃烧和污染物NOx生成-还原模型，采用计算流体力学方法，模拟其燃烧过程，促进了再燃低NOx技术应用的推广。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
