Why the other one? Because there was a self-description of a Φ3.3m kiln cement clinker production line in January this year. The Φ3.3m kiln, which was built a few years ago and located in another city in the province, is the one I want to describe now.
I was issued a birth permit by the province in 2004 and was born in 2005. From the birth permit to the list of provincial production lines, it has always been registered on the production capacity of 2500 t/d new dry process cement clinker production line. For example, the actual capacity is only 1167 t/d according to the cement clinker capacity conversion table of the capacity replacement method in 2021 and before, which is 1.14 times larger than batch. In the list of provincial clinker production line in 2023, the design capacity is marked as 2500 t/d, and the capacity converted according to the measured kiln diameter is marked as 1167 t/d.
Looking back, first, the provincial competent department was really far-sighted and defined the production line as 2500 t/d new dry process cement clinker production line on the birth permit, which not only avoided the industrial policy restrictions in 2005, but also made me avoid the industrial policy restrictions in 2011 and later. It is not included in the restricted category, not only because the electricity consumption in production is not increased, but also because the proportion of capacity replacement will be increased from the current capacity replacement method in 2021, and the 2:1 reduction replacement of restricted capacity will not fall on my head. Second, if the actual capacity replacement is calculated by the cement clinker capacity conversion table, it is less than half of the approved capacity, which is too bad. Fortunately, I have to endure until 2024 when this capacity replacement method is introduced. The new policy stipulates that the amount of capacity used for replacement shall be determined strictly according to the capacity specified in the project filing (approval) documents. Now, if it is used for replacement, it can be "justified" to take 2500 t/d as the base, and the market value of its capacity index can be much more, making a lot of money.
In January this year, my 2500 t/d production capacity was split into two parts, which were sold to Φ3.6m kiln and Φ4.7/5m kiln respectively in the way of 1.5: 1 reduction replacement to supplement production capacity. A total of 1666 t/d was supplemented for them by a reduction of 1.5: 1. According to the old method, plus the (should be) restricted category, only half of 1167 t/d can be added with 584 t/d, and the reality is that 1082 t/d is added. No wonder the brothers of the Φ3.3m kiln called me too lucky.
On June 11, the provincial authorities announced that the capacity replacement plan had not been organized and implemented for some reason and had been revoked, which was a bit frustrating at that time. Of course, the revocation only needs to be announced, and there is no need to explain the reasons. The announcement added "for some reason" purely for the sake of silky and delicious sentences.
Unexpectedly, only 20 days after the cancellation, the provincial authorities announced the capacity replacement scheme of six phosphogypsum acid co-production cement clinker production lines in four projects. Among them, the annual output of cement clinker for two lines is 750,000 tons, and the required cement clinker production capacity index of 2,500 t/d is provided by us. According to this capacity replacement method in 2024, the new cement kiln production lines in Hubei, Yunnan, Guizhou, Sichuan, Anhui and other five provinces dispose of phosphorus (titanium, fluorine) gypsum, and replace more than 70% of limestone raw materials, the equivalent replacement will be implemented.
No, I have contributed to supporting cement enterprises and phosphorus chemical enterprises in key areas to jointly develop phosphogypsum resource utilization, and put on the hat of "green" development. 2500 t/d index 1 t/d does not fall, 100% in place. Compared with the capacity replacement plan in January, it is much more atmospheric and affordable, and it feels "immeasurable merit"! Can
this "large" production capacity really be "wantonly" used for replacement?
When the competent authorities interpreted why the implementation measures of capacity replacement should be revised in 2024, they pointed out that the 2021 edition should be revised to promote industrial layout adjustment and green low-carbon transformation by strictly identifying capacity, improving the standards of new projects and simplifying the procedures of cross-provincial mobility. Promote the cement and glass industry to achieve high-quality development.
What is through strict capacity identification? It is indispensable to reasonably supplement the production capacity of the "batch of small and large" production lines, strictly identify the "batch of large and small" production lines, and determine the reasonable production capacity. The cement clinker production capacity calculated only by kiln diameter is quite different from the actual production capacity, which is not very accurate. However, they turn a blind eye to the "big batch" and use the new regulations to replace the number of production capacity, strictly on the basis of the clear capacity determination of the project filing (approval) documents, "brazenly" use the "big batch" production capacity fully and "steal self-joy", in order to further consolidate the achievements of the cement and glass industry in capacity removal, optimize the industrial layout and promote the market. The spirit of promoting high-quality development of cement and glass industry is inconsistent. When it comes to
"blatant" words, it is not entirely true that this "batch of large" production capacity is still a bit "guilty". In the column of specification, model and quantity of main equipment in the capacity replacement scheme, the column of rotary kiln diameter * length should have been filled in, but it was hidden, and it was replaced by one 2500 t/d new dry process general cement clinker production line (when the capacity of two projects was supplemented in January, it was the same in one of the projects). If you are not "guilty", why not use a set of Φ3.3m * 52m rotary kiln with decomposition furnace?
It is also noted that the transferred capacity project for the three co-production lines of the other two projects is a Φ4.3m * 64m cement clinker production line. In 2006, the approved production capacity was 4000 t/d. According to the capacity conversion table of the previous capacity replacement policy, the capacity shall be 3000 t/d. By the end of 2023, the list of provincial clinker production line shows that the converted capacity of measured kiln diameter is 3500 t/d. 4000 t/d is used in this replacement. When the project was born, it was "large batch", and when the capacity was replaced, in fact, it also used "large batch" capacity.
