Applications


Online Ash and Moisture Analyzer  (AMA-D) independently developed by DFMC is directly installed on the coal conveyor belt and directly performs on-line detection of the whole coal flow, avoiding the problem of poor sampling representativeness. It can be widely used in coal mines, thermal power plants, coal washery, coal blending plants and coal terminals for on-line inspection, and can also be used for automatic adjustment and control of the production process in coal preparation and coal blending processes.

1.Real-time analysis: The detection of the coal flowing through the belt is totally real-time. The analyzer can give the instantaneous value and average of coal ash within any time period according to the needs.

2.Representative measurement result:The analyzer analyzed all the coal flowing through the belt and overcame the shortcomings of poor representativeness of the results of traditional assays, taking only small portions for analysis.

3.Adaptability:The analyzer uses the principle that signals can penetrate matter to achieve non-contact measurement. 


1.Accuracy Clean coal ≤ 0.5% Raw coal with low ash content ≤ 1.0% Raw coal with high ash content ≤ 2.0%

2.Accuracy of moisture measurement 5%~10% ≤ 0.5% 10%~20% ≤ 1.5% More than 20% ≤ 2.0% 

3.Thermal value reference accuracy (specific accuracy is given based on site conditions) Clean coal ≤ 100Kcal/Kg Raw coal with low ash content ≤ 150Kcal/Kg Raw coal with high ash content ≤ 200Kcal/Kg


Online Ash and Moisture Analyzer  (AMA-D) can be widely used in coal mines, coal washery, coal blending, coking plant, coal- fired power plants, steelworks, coal wharfs, etc. for on-line measurement; it can also be used for coal preparation, coal blending process to automatic adjust and control the production process.
