Phosphogypsum and flue gas from power plants burning high-sulphur coal will be the vast potential resources.

磷石膏及燃高硫煤电厂的烟气是硫的巨大潜在资源。

The results show that coal and gangue are involved in the microbial role; the quantity of inoculums is directly related to the quantities of gas and the contents of methane, at the same time it has a certain degree of impact on the contents of NO(superscript - subscript 3)-N, NH(superscript + subscript 4)-N, S(superscript 2-), SO(superscript 2- subscript 4), and metals; moreover, because of the microbial anaerobic fermentation, the contents of NH(superscript + subscript 3) are seriously substandard; overall, the group B which has a smaller proportion of gangue has a less impact to the environment compared to the group A which has a larger proportion of gangue.

结果表明：煤、煤矸石参与了微生物作用；接种物的加入量与产气量和甲烷含量密切相关，并对硝酸盐氮、氨氮、硫化物、硫酸盐和金属也有一定程度的影响；同时由于微生物厌氧发酵的关系，氨氮严重超标；矸石比例较小的B组对环境的影响略小于矸石比例较大的A组。

The S entering into pellet with concentrate is pyrite, with coal powder are iron sulfide, sulphate and organic sulphur, when reducing, S existing in pyrite, iron sulfide and organic sulfur come into gas phase, then been absorbed by fresh Fe and liberate out of pellet, combined with CaO existing in outside of the pellet to form CaS finally, sulphate will remain in DRI.

当还原温度高于在铁碳相图中的最低液相线温度1147~1153℃时，渗碳作用导致DRI外壳熔化，这层致密的熔融外壳起到热态直接还原铁的防氧化作用。低于这个温度将有助于还原和脱硫。

A modified k-ε model,a k-ε-kp gas-particle model and a EBU-Arrhenius model is applied in the simulation of turbulent free jet flow of pulverised coal combustion in different load cases.

采用修正的k-ε湍流模型，利用k-ε-kp气固两相模型和EBU-Arrhenius燃烧模型模拟了不同工况下煤粉气固两相自由射流燃烧的过程。

The invention aims to solve the problems of the prior W-shaped flame boiler adopting overfire air nozzles in direct flow structure form, such as higher carbon content in fly ash resulting from the fact that the gas and pulverized coal in the jet flow of the conventional boiler are unlikely to be mixed with those between adjacent jet flows due to the poor lateral diffusion capacity.

本发明的目的是为解决现有W型火焰锅炉燃尽风喷口采用的都是直流的结构形式，其射流的横向扩散能力较弱，无法与相邻射流之间的烟气和煤粉混合，造成飞灰含碳量偏高。

Heating is one of the most important processes in heattreatment .and there are many ways to heat,such as charcoal,coal,liquid and gas fuel.

加热是热处理的重要工序之一。金属热处理的加热方法很多，最早是采用木炭和煤作为热源，进而应用液体和气体燃料。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
