In oxygen deficient high temperiture combustion, the amount of volatic material evolved influene the conversion of sulfur in coal, high volatile content restrains the oxidation of pyrite and iron sulfide , which causes compavatively large amount of iron sulfide left in char. At the condition of air coefficient α=0.4, the sulfur conversion is up to 87% for SHONGZHAO anthracite coal, 72% for FORGCHANG bituminous coal, and the conversion is compeleted within 0.5 see.

在高温贫氧状态下燃烧，煤中硫的释出率高于煤的燃烧率，高挥发份将抑制黄铁矿的氧化释放出来，即影响煤中硫的释出率，在过量空气系数为40％时，松澡无烟煤能达到87％的硫的释出率，丰城烟煤达到72％的硫的释出率。

The organic facies are researched in the region, the result indicated: coal rock is mainly the better hydrocarbon source rock and has better latent capacity of producing oil and gas. Feature of reservoir was analyzed, the result indicated: from south to north of along qiguang fault, the depth of coal bed augments inch by inch; the coal bed thickness accretes at first and then decreases until steady.

通过对研究区的煤岩有机相特征的研究，得出：煤岩主要为较好烃源岩，具有较好的生油气潜力；分析了煤储层特征，结果表明：在垂直齐广断裂由南往北方向上，煤层埋深逐渐增大；煤层总厚度先增大后减小至稳定。

According to these features, a hybrid genetic algorithm is developed to optimize the operation of pulverized system in admixing combustion conditions, where a fuzzy neural network is adopted to evaluate admixed coal's slag property, and a radial basic function neural network is used to predict pulverized coal's fineness and mill's outlet temperature.

本文将人工神经网络和遗传算法相结合形成混合优化算法，对电站多煤种掺烧制粉系统运行进行寻优。针对掺烧煤结焦的模糊性和非线性特征，采用模糊神经网络评估混煤的结焦特性，并利用径向基神经网络关联掺烧煤的煤粉细度和磨出口温度。

In order to realize the pre-mixed water jet flow ultra fine coal comminuting devices automatic control, raises the fine coal of smashing efficiency and the product quality, designed the pre-mixed water jet ultra-fine coal comminuting configuration monitoring system.

摘 要：为实现前混合水射流超细煤粒粉碎装置的自动控制，提高煤粒粉碎效率和产品质量，设计了前混合水射流超细煤粒粉碎装置的组态监控系统。

In the producer gas sulfur originates in the gasification uses the coal, mainly by the H2S form existence, gasifies with the coal in the sulfur has 80% to transform H2S approximately to enter the coal gas, if, gasifies with the coal including the sulfur quantity is 1%, after the gasification changes over to in the coal gas to form about H2S approximately 2-3g/Nm3, but professions and so on ceramics, kleit contain the sulfur quantity request to the coal gas are 20-50 mg/Nm3; If in after coal gas H2S burning transforms SO2 is completely about 2.6g/m3, stipulates the SO2 highest emissions density target compared to the country to outdo many.

发生炉煤气中的硫来源于气化用煤，主要以H2S形式存在，气化用煤中的硫约有80％转化成H2S进入煤气，假如，气化用煤的含硫量为1％，气化后转入煤气中形成H2S大约2-3g/Nm3左右，而陶瓷、高岭土等行业对煤气含硫量要求为20-50 mg/Nm3；假如煤气中的H2S燃烧后全部转化成SO2为2.6g/m3左右，比国家规定的SO2的最高排放浓度指标高出许多。

It mainly includes the technologies of removing organic sulfur from coal, gasifying coal and in liquefying coal .
