Test the moisture content of the raw coal
Thread Content
The raw coal has a high moisture content when it arrives, but the test results show a lower value; how can we make the result closer to the actual value?
That mainly relates to the issue of sample collection and preparation, and it is also connected to the testing procedures. Inspections must be carried out strictly in accordance with the standards for sample collection and preparation as well as the moisture testing standards; furthermore, parallel samples must be prepared.
What is visible does not reflect the actual situation; when there is more coal present, the moisture content within the coal chunks is lower. It may seem as though water is flowing with the coal being transported, but when a sample is taken, the moisture content is actually lower than that of coal powder that isn’t accompanied by flowing water:lol :lol :handshake
The three steps of sampling, sample preparation, and testing should be carried out in a concise and sequential manner; especially during the spring and autumn when the weather is dry and water evaporates rapidly, the time intervals between these steps have a significant impact on the results.
What you see is just one part of it; there are rules regarding sampling, and it’s important to ensure representativeness. What do you mean by high moisture content? Is this the case in general? After sampling, there is a process for preparing the sample, and care must be taken to prevent the moisture from evaporating. There should be no problems during the analysis process.
