Embodiment Construction
[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0019] Such as figure 1 As shown, the method for using CDQ dedusting ash in the coal blending process includes the following process steps:
[0020] (1) The dedusting ash produced every day by CDQ is transported to the coal storage yard by car through the ash discharge port, and unloaded into low-sulfur coking coal with a sulfur content of <0.4% and low-ash lean coal with an ash content of <8.5%. Separate storage near the lean coal;
[0021] (2) Mix CDQ dedusting ash with low-sulfur coking coal with sulfur content <0.4% and low-ash lean coal with ash content <8.5% according to the weight ratio; Coke CDQ dedusting ash and low-ash coking coal and low-sulfur lean coal in a weight ratio of 1:5:5 are fully matched and evenly formed into a new mixed dedusting ash;
[0022] (3) Transport the uniformly mixed dust ash in step (2) to the coal blending bin, and...
