In coal gasification techniques, the gasifier is the key equipment which directly affects gasification characteristics, therefore flameless oxidant technology was applied to the design of new gasifier for high ash melting coal, and gasification characteristics in the gasifier were carried out by not only experiments under cold state and therma1 state, but also numerical simulations in this paper.

由于气化炉是煤气化技术中的最关键设备，因此，本文以高灰熔点煤的高效气化为背景，归纳分析了各种先进干煤粉气流床气化炉的炉型结构，将无焰氧化技术应用于粉煤气化，提出了一种基于无焰氧化的新型干法进料煤粉气化炉，进行了炉内冷态、煤粉气化的热态试验和数值计算，分析了高灰熔点煤在该气化炉中的气化特性，并以此为基础，对气化炉的结构进行了优化，提出了无焰氧化分级气化炉，对高灰熔点煤在该气化炉中气化特性进行了数值计算与分析。

Then, gasification experiments of high ash melting point coal with dry pulverized coal feeding were carried out on the gasification test system, the flame images were observed to validate the feasibility of flameless gasification inside the gasifier, temperature distributing inner the gasifier and syngas components were measured under different / atom ratio and steam/coal ratio conditions.

进而，建立煤粉气化炉的物理和数学模型，运用概率密度函数方法对高灰熔点煤在基于无焰氧化的煤粉气化炉内的气化过程进行了模拟计算，参照小试的试验工况，验证了气化炉模型；分析了不同氧碳原子比、蒸汽煤比和气化压力对高灰熔点煤气化特性的影响，并可视化地研究在典型工况下高灰熔点煤在该气化炉中气化过程，为进一步炉型结构和气化工艺的优化设计提供依据。

From the bottom up, the strata are the Fuxian, the Yan'an, the Zhiluo and the Anding Formations. In the past, it was thought that only the Yan'an Formation contains coal in the Jurassic systerm of the basin. However, recent explorations have shown that the Zhiluo Formation also has some minable coal seams in a certain area.

以往认为鄂尔多斯盆地的侏罗系延安组为含煤岩系，其他均为不含煤的地层，在近几年来的勘查中，发现直罗组也存在具有一定分布面积的可采煤层，笔者通过直罗组岩石露头、钻孔岩心和测井曲线的分析研究，划分了直罗组沉积相，并探索了直罗组的聚煤规律，对煤层进行了预测。

The research shows that these basins alternate between uplift and concave and that their spreading directions follow certain rule. The 6 NEE-trending basins are of early Jurassic epoch, some of which may contain coal-bearing strata and minable coal seams of Beipiao Formation. The 12 NNE-trending basins are all of early Cretaceous epoch, among which Badaohao, Leijia and Xielintai Basins have relatively good coal-bearing property and can serve as coal-searching prospect area.
