How to determine the residual carbon in coal cinders
Thread Content
To improve the utilization rate of coal, it is now necessary to determine the residual carbon in coal cinder! May I ask how to determine the residual carbon content in coal cinders?

This relates to the representativeness of the samples; therefore, the samples collected by the analysts have a significant impact on the analysis results, which means that errors can be quite large. When I performed this type of analysis in the past, I used a simple method taught to me by my former teacher: 1. Place the slag produced by each batch separately. 2. Take samples from several different points within each batch of slag. 3. Collect at least 3 KG of sample material. 4. Use a large sieve to wash the sampled material in water, thereby removing the slag. 5. What remains is carbon. 6. The amount of carbon can be determined simply by visual inspection. 7. With this method, those carrying out the operation usually don’t need to say anything – it’s easy to compare the results and ensure fairness
In the laboratory, the method of measuring side ash can be used to determine whether combustion was complete: an analytical balance is used to measure the weight difference of the coal ash before and after high-temperature heating, making sure that the coal ash is dried first.
