无烟煤

Although there is a little carbonite caused by some magmatic dikes in the CarboniferousPermiam coal, most Carboniferous-Permian coal has no great differences in vitrinite reflectance, crystalline indices, bulk specific gravity, hardness, and the content of velotile matter from the Jurassic coal, and both are super-anthracite.

区内石炭—二叠系煤与侏罗系煤除了前者含有一些由侵入体造成的天然焦或半焦外，二者均为超无烟煤，在镜质体反射率、煤晶核结构、显微硬度、挥发份和容重等方面上均没有明显的差异，说明区域变质是在煤系地层沉积之后发生的。

For the exploitation of mineral resources, there are 10 species, of which, anthracite, coal-bed methane, pyrite, clay, bauxite mining stone of the most value.

可供开采的矿产资源有10余种，其中，无烟煤、煤层气、硫铁矿、粘土、矾石最具开采价值。

The corrosion rate of plain carbon steel contacted with higher coalification such as anthracite coal is 2 to 3 times larger than that in brown coal .

在相同的其它条件下，碳钢的腐蚀速率随接触的煤的煤化度提高而增加，与发育良好的无烟煤接触的碳钢的腐蚀速率是在煤化度相对较低的褐煤中的2～3倍以上。

An industrial experiment were conducted to test the influence of excess air coefficient and secondary air ratio on the carbon content of fly ash of CFB boiler burning Fujian anthracite.

煤质特性及锅炉运行工况是影响飞灰含碳量的2个重要因素。福建无烟煤由于挥发分低、固定碳含量高，反应性差，难于着火和燃尽。

The combustion characteristic of the BCC containing 5%~35% of the corn haulm was studied by the thermo gravimetry under different experiment conditions.

以无烟煤、玉米秸秆和黄土为原料，研究了玉米秸秆含量为5%~35%的生物质型煤在不同试验条件下的燃烧特性。

The biomass compound coal composed of anthracite coal,corn haulm and loess was taken as the object of study.

BCC is composed of anthracite coals as the raw coal,haulm of the corn as the biomass and loess as the cementing agent.

原煤选用无烟煤，生物质选用玉米秸秆，黏结剂选用黄土，制备生物质型煤。

The results show that when the mass ratio of sodium jarosite residue to anthracite is 5∶1, reduction roast lasts at 800℃for 0.5 h, leaching is carried out at 70℃for 40 min by 0. 5 mol/L H2SO4 with liquid-solid ratio of 7∶1, 93% of both iron and nickel can be leached out.

研究结果表明：当黄钠铁矾渣与无烟煤按质量比为5∶1均匀混合，在800℃还原焙烧0.5 h，焙烧渣用0.5 mol/L硫酸溶液按液固比7∶1在70℃浸出40 min时，渣中93%的铁和镍进入浸出液中。
