Ⅰ. The Coal Classification Method for the Chinese Coals. (а) The Ultimate Analysis Graphical Coal Classification Method-Use the volatile Mateer on Combustible basis Vr as abscissa and the simplified coal characteristic coefficient as ordinate. (б) Proximate Analysis Graphical Coal Classification Method-Use the volatile matter on combustible basis VT as abscissa and the fixed carbon on ash free basis F. C.w Ⅱ. The Ranks (kinds) of the Chinese Coals-By using the two above mentioned graphi- ed coal classification methods, the Chinese coals available with ultimate analysis or proximate analysis data can be easily classified into the following different kinds as known internationally: -anthracite (A), semi-athracite (T), semi-bituminous ( C), coking coal (k), steaming fat coal ( ), gas coal ( ), long flame (candle) coal ( ) and lignite coal ( ), as tabulated on Table - 4. Ⅲ. The Properties of Chinese Coals. (а) The composition of the Chinese Coals - with the exception of ash and sulfur which vary irregularly, the other constituents. like carbon, hydrogen, oxygen, nitrogen and analytical moisture vary regularly with the variation of the vodatile matter on combustible basis V in the different stage of carbonization. (б) The Reltation between the ultimate analysis and proximate analysis for the Chinese Coals- In the bituminous coal region, the data of proximate analysis can be transferred to the ultimate analysis proximately according to the straight line formula, as for the bituinous coal. The other constituents like H, O and N, S can also be obtained by the straight line formulas as shown on the graph. (в) The Heating Value of Chinese Coals - The Heating Value of Chinese Coals; when only ultimate analysis data is available, can be checked by using the Mendeleef formula; when Duly the proximate analysis data is available, the heahng value can be checked by the Goutal Formula. When illers is only the ultimate data without any bomb calorimeter, the heating value can be obtained by the following empirical formulas:(p) The Coking Property of the Chinese Coals---The ebbing property can be represent6d by' foe coking coeffident as suggested by the author, the ratio of hydrogen to oxygen on combustible. basis (%). With the exception of anthraede, semi--anthracite and liana, ' which will have the ash in powderform, when burned, the other bituminous coals like (1) Semi--bituminous and part of the coking coal, when Vr- 16 ~ 24 7o and (%) = 0.90 1 .8, the ash after combustion will become softly caked; (2) for coking coal, Steaming fat Hr coal and gas coal, when Vr~25-47 and M~0. 58-1 .2, the ash after combustion will become strongly caked; (3) FOr gas coal and long flame coal, when Vr~31 ~46 ac and aam: =0. 34-0. 50, the ash will become softly caked. f {if) The Combustion Characteristics of Chinese Coals -- The combustion characteristics vary with the kind of coal. Which kind of coal is suitable for what kind of industrial use and which type of furnace is suitable for burning what kind' of 'coal,. all depends uPOn the rank, composition and combustion charact6rislics of the coal. F6, economy, it is necessary >to burn the poor quality coal nearby and the problem of caking inside the furnace resulting from poor quality coal muSt be properly solved. ' (in) The ash Fusion point of Chinese Coals -- The ash composition affects the fusion point. greatly. The change in ash composition will of feet the fusion poillt. Thus increasing the met,ilie oxides in the coal ash liko FeZO3, CaO and MAO ate. will raduce the fusion point and will fadlitate the ash disposal in fluid form. On the other hand, whother increasing 'the kaolin (fire clay) in the ash composition will raise the ash fusion point or not is a problem worthy for further investigation and research. ' '. It may be reaseonably assumed as suggested by the auther that the coal ash is mainly consisted of kaolin (Al.O, ZFios ZHZO) + free SiOZ + different motailic odddes (FavOr, CaO and MgO, etc ). When coal is burned, the free SiOZ will combine with some of the metallic

The simplified Coal characteristic Coefficient β' = 2.35, as proposed in author's two previous papers to ho used with Vr for coal classification, has been for the first time repeatedly proved as shown in many graphs (Fig. 2-Fig 9) to represent (a) the foundamental characteristics of coal, like caking property, heating value, plastic layer thickness. etc. (b) the quality of the side Chain of the coal crystal (c) the percentage proportion of vitrain composition with respect to the other constitutents in petrographic...

The simplified Coal characteristic Coefficient β' = 2.35, as proposed in author's two previous papers to ho used with Vr for coal classification, has been for the first time repeatedly proved as shown in many graphs (Fig. 2-Fig 9) to represent (a) the foundamental characteristics of coal, like caking property, heating value, plastic layer thickness. etc. (b) the quality of the side Chain of the coal crystal (c) the percentage proportion of vitrain composition with respect to the other constitutents in petrographic components, during the different stages of coalification. (2) The simplified coal characteristic coefficient β' can be used to substitute the free swelling index, Roga number L.R. and the plastic layer thickness y etc in the coal classification of type together with the volatile matter on combustible basis VP for the coal classification of rank. (graph 10-graph 16) (3) Besides the VP and β' coal classification system,(Fig - 18), Carbon content on combustible basis CP with the free hydrogen H°= (HP=)for coal classification (Fig-23), VP vervus classification (Fig.-24), VP versus H°(Fig. -25) and VP versus (Fig-26) coal classification are also proposed. Comparisons of the different systems are made with the conclusion of adopting VP versus β' as the most logical system. (4) In the VP versus β' graph; the plastic layer thickness y curves (Fig.-27) represent the the rate of vitrinification during the different stages of coalification due to the different constituents of principal peat-forming plant substances. So a new international three-parameter coal classification system is proposed with the volatile matter on combustible basis VP as the first parameter and the simplified coal characteristic coefficient β' as the second principal parameter with the thickness of plastic layer y in mm as the third parameter. (Fig-28)

(1)简化特性系数β’=2.35代表着煤的分子结构中侧链的本质,而纯燃质挥发分 VP代表着煤的原始物质中侧链与核心部分的相对数量. (2)简化特性系β',即自由氢碳比率函数,是煤岩成分比例不同的标志;角质类和不透明质与透明基质数量的相对比例的标志;是镜煤质与非镜煤质含量相对数值比例的标志,亦即是镜煤化程度的标志。 (3)简化特性系β'反映了煤的特性,焦油产率,炼焦性质,胶层厚度,发热量及碳含量,氢含量,氧含量等,并有充分的证明。 (4)简化特性系β’揭露了近百年来国际间对於煤的特性的秘密,而是国际上有最完善的理论根据的分类指标。 (5)因此,作者建议(a)用VP及β’来作为中国煤工艺技术分类指标(6)用VP,β'与y作为国际煤分类指标,其中 厚度y,根据作者的见解,代表着煤在碳化过程中,凝 化的速度的标志。

应用煤岩相方法並結合煤的化學和工藝性質分析,對本溪煤田煤的煤質做了較系統的鑑定。結果指出:本溪煤田的變質程度沿煤田的走向由東北向西南加深,而沿煤層深度的變化则與Hilt定律相反,上部煤層的變質程度較下部煤層為深。寳砟層煤中的絲炭存在形態和其含硫量較低可作為此煤層是異地生成和陸相形成的特征之一。煤岩相的宏觀和微觀觀察說明了本溪煤田中的煤層主要由光輝層狀煤構成。煤的顯微組分絕大部分是鏡煤類物質,角質類物質發現的極少。煤的可選性隨着煤層的加深而下降,這一現象與煤層中所含夾石層的數量以及煤岩組分中浸染礦物質的程度有關。根據煤的工藝性質,本溪煤屬於好的煉焦煤。
