This manual is a muchneeded revision of an earlier USGS publication, Coal Petrographic Laboratory Procedures and Safety Manual (Moore and Stanton, 1985). The development of new sample preparation and analysis techniques has necessitated both an overhaul of many established procedures and the adoption of new ones.
Coal for metallurgical coke production: predictions of coke quality and future requirements for cokemaking Dı´ez*, R. Alvarez, C. Barriocanal Instituto Nacional del Carbo´n (INCAR), CSIC, Apartado 73, 33080 Oviedo, Spain Accepted 31 October 2001 Abstract
Jul 18, 2013· To understand the effect of coal fluidity on coal blending and there by the coke quality, studies have been conducted using the industrial scale coals and coal blends. An empirical relation has been developed between actual blend fluidity and calculated fluidity using logarithmic weighted average from fluidity of individual coals.

evaluation (refer Appendix A) and it is anticipated that coal analysis work carried out in Australia will be conducted according to these standards. AS1038 is the prefix used to identify the principal Australian Standards that detail the methods for analysis, testing and reporting of quality in higherrank coal .
The RETSCH pulverizer range covers applications from the preliminary size reduction of particles of several centimeters to fine grinding down to the nano range. A good pulverizer guarantees reproducible sample preparation, which is the basis for any reliable and accurate laboratory analysis.
temperature region of the coal depends on the type of ) Therefore, the thermoplastic and dilatation behavior of a coal blend cannot be elucidated from simple measurements of fluidity and expansion ratio of the coal blend. At present, addition of a binder is a popular method for increasing coke
