possible coal samples.“

Coal Analysis

Field Sampling:

As with most analytical testing, gathering a proper and representative sample is the most important step to obtaining accurate analytical results. Sampling for coal analysis is no different. Geochemical Testing sampling teams are trained and experienced in collecting samples in accordance with both ASTM D 2013 (Standard Practice for Preparing Coal Samples for Analysis) and ASTM D 2234 (Standard Practice for Collection of a Gross Sample of Coal). These practices ensure that a representative sample is collected for our client’s analytical needs.

    • Size, Luster, Quantity, etc.
    • Check for Impurities (Wood, Shale, etc.)
  • Sampling
    • Stock Piles
    • Railroad Hopper and Truck
    • Prep Plant
    • Channel Sample

General Coal Analysis

While all coal may look the same, it does not burn the same. Determining the coal quality is not only important for valuing purposes, but also for protecting equipment, plant efficiency and environmental impact modeling. Geochemical Testing offers a wide range of coal quality analyses from basic to complete. We understand the importance of timely results as well, which is why our coal department operates on a 24-hour basis Monday through Friday.

Ash Analysis

One of the byproducts of coal combustion is the creation of ash, namely bottom ash and fly ash. Bottom ash generally falls out and is collected during the combustion process. The lighter fly ash, in past times, would have gone out the smoke stack, but modern pollution control mechanisms now trap and collect the fly ash. The goal with either type of ash is to find a beneficial use (creating concrete, asphalt, bricks or for use as soil stabilization, clean fill). Ash that does not meet standards for beneficial use may be treated to meet the criteria. The alternative to both processes, and usually the more expensive option, is to simply dispose of the ash. Geochemical Testing has the capability to determine the quality of the ash and takes pride in assisting our clients in finding new/innovative ways to treat ash for beneficial use.

Power Generation Analysis

Geochemical Testing (GT) strives to meet the needs of our power generations clientele from the beginning of the process to the end. Our coal services can determine the quality of a potential coal purchase, the characteristics of the coal for plant efficiency, the ashing properties of the purchased coal, and the disposal options of the ash byproduct. Our environmental services can provide analysis for National Pollutant Discharge Elimination System (NPDES) permits or ash landfill monitoring requirements.
