    Standard Practice for Manual Sampling of Stationary Coal

    Sampling technicians must never work in coal that is piled or in railroad cars over hoppers and/or feeders or where there is the possibility of the coal being eroded from beneath them. Sampling should never be performed near a face of a stockpile where the face extends upward at an angle greater than the angle of repose of the coal. 7. Procedure

    The Analysis of Coal and Analysis techniques

    The analysis of coal determines the following aspects: 1. Measurement of moisture The moisture content is being determine by placing a sample of powdered raw coal of size 200- micron in an uncovered crucible which is placed in the oven kept at 108 +2 °C along with the lid. After that sample is cooled to room temperature and weighed again.

    CHAPTER 4 RESULTS AND DISCUSSION COAL ANALYSIS

    chemical composition of the coal used in the study. These differences in compositions are attributed to the particle size of the coarse coal samples, which ranged from 13.2mm to 2.36mm, possibly producing heterogeneity that affected the sampling process. The XRF analysis of the feed coal sample to gasification indicated that this sample
