With the distribution and the industrial quality index analysis on the vitrinite reflectance of the single coking coal and blinded coal from one company in the recent years,it was found that the industrial quality of the single coal was quite stable and the vitrinite re- flectance and distribution had a high variation.

In order to provide a technical base for the Coking Plant to select coal blending ratio,lots of single coal from the Coking Plant have been made singly in the 20kg experimental coke oven,and the coke strength and sieve composition of every single coal are obtained.

Through carrying on experiment on coke reaction, optical textures before and after the reaction are studied to calculate the intensity of coke reaction, and then characteristics of each single coal can be use effectively so as the coal blending can be reasonably made to increase the coke hot reaction strength.

Effects of coal type and carbonization conditions on the surface properties of activated coke;

The effects of coal type and carbonization conditions on the porous texture of activated char derived;

The effects of the coal type and the hot-briquetting process parameters on the strength of the Carbon Composite iron ore hot Briquette(CCB) are investigated,and the mechanism of the CCB strength is discussed.

Base on element and lithofacies analysis of coals,it was discussed that the relationship the kind of coal with productivity of hydrogenation reaction.

In the process of coal based DR, the results of the product is greatly affected by the kind of coal, especially its reactivity, content of ash and content of volatile.

Adaptability questions for coal variety of SG1 025 t/h boiler have been studied and tested in this paper, the paper analyzed the security and economy while burning different coal variety of this boiler,conclusion and suggestion that instrust the boiler running have been proposed.

The fineness of coal powder from the pulverizing system and the coal variety effective on the fume discharge temperature of boiler have been analysed in the paper.

This paper approaches the adaptability problem of coal rank for large size utility boiler from the fuel coal characteristies,e-quipment configuration and operating conditions the three aspects and seeks after the optimum coupling of boiler type and coal property through coal-batching and blended-coal firing as well as adjusting and testing.

This paper systematically expound the characteristics and functions of the contentwide data source stored in the data bank of chinese coal rank source, these data include the coal resource of the national productive mining areas and prospecting areas, production, coal quality, transformation and combustion.

Burner reconstruction to improve coal species adaptability of 420t/h coal burning boiler;

Presents the requirement of water coal slurry gasificafion to coal,determination of coal mines for water coal slurry gasification as well as specific sampling method of coal species.
