Convenient for guiding coal washing, blending and other process operations.

This system can also simultaneously detect coke pore parameters and coke optical texture composition.

●Applications in coking production:

1. Pre-purchase coal type evaluation: Judge the true quality of pre-purchased coal from both metamorphic degree and coal petrographic composition, whether it is a typical coal type, etc. Combined with conventional indicators, scientifically guide coal type procurement.

2. Incoming raw coal quality control: Quickly and accurately identify single/blended coal and coal active/inert ratio composition, comprehensively and scientifically assess coal quality.

3. Guide reasonable stacking in coal yard: Using the principle that coals with similar vitrinite reflectance distribution have similar quality, arrange stacking in the coal yard reasonably to prevent large production fluctuations caused by unknown secondary blending in the plant.

4. Monitor coking coal blend ratio: Obtain the true proportion of "active components" with different coking characteristics, not misled by the appearance of "surface coal type ratio". Prevent large fluctuations in coke quality and mis-allocation or omission in other production links; effectively stabilize coke production.

5. Refined coal petrography blending: Guide coal blending from a coal petrological perspective, refine proportioning operations, save huge costs, reduce waste.

6. Coke pore distribution detection: Reverse deduce reasons for coke quality changes, verify the rationality of blending "concepts", compare the impact of different blended coals on coke quality, etc.

●PETRO 200AIThe system currently achieves ten "innovative technologies":

1. Adopts the advanced "multi-feature intelligent recognition technology" in current coal petrography automatic measurement and control field, with very high recognition accuracy for vitrinite! (Holds multiple invention certificates!)

2. Has the function of simultaneously providing vitrinite reflectance and distribution as well as coal petrographic composition (active/inert ratio) in one scan, the entire process is fully automatic without manual intervention, high accuracy, comprehensive coal quality evaluation!

3. Combines fully automatic scanning with rapid sample preparation, can test 15-50 samples per day (8 hours), a truly instrument that meets the needs of supervising large batches of incoming coal!

4. Currently the only device that can detect whether lignite or anthracite is blended in incoming coal solely through automatic scanning! Effectively prevents the entry of "extremely poor coal quality" coal.

5. Measurement area control can achieve "soft centering", replacing the traditional inconvenient "aperture plate limit - measurement diaphragm" method! Measurement area less than 2 micrometers! Purer vitrinite measurement!

6. Block coke porosity measurement achieves "front peak dynamic recognition and segmentation technology" (patented technology!), solving interference from sample grinding and coke wall composition differences, accurate results, fast speed (2min/sample)!

7. Creatively uses direct-read 16-bit (65536 levels) underlying RAW data technology, solving the contradiction that traditional photometer method has sufficient precision but cannot identify components, while image method can identify components but has insufficient precision. Integrates component intelligent recognition with high-precision detection in one! Truly achieves high accuracy, high precision, fully automated rapid coal petrography detection technology. At the same time retains manual detection functions strictly in line with national standards, with precision and stability superior to traditional photometers.
