A few days ago, Guizhou announced a 6833t/d cement clinker production line project supplementary capacity replacement plan, which shows that the main equipment specification model and quantity Φ5.4/5.8 × 78m rotary kiln ; The design capacity after supplementation is 6833t/d; the replacement (import) capacity is 2333t/d; the replacement ratio is 1.5: 1.
According to the list of 2022 cement clinker production line published by Guizhou Provincial Office of Industry and Information Technology (up to now, there is no list of 2023 cement clinker production line in Guizhou Province) , the main equipment specifications of the production line are Φ5.4/5.8 × 78m. The design capacity is 4500 tons/day, and it will be completed and put into operation in May 2011.
According to the cement clinker capacity conversion table of previous capacity replacement methods , when the production line specification is Φ5.4/5.8 × 78m, the corresponding actual capacity should be 8500t/d. However, the design capacity listed is only 4500t/d. The actual capacity is 1.89 times the design capacity, which is only one step away from doubling. Now, even if the 2333t/d capacity to be supplemented is taken into account, the re-filed capacity is 6833t/d, which is only 80% of 8500t/d. In fact, considering the continuous progress of production technology and equipment level, 8500 t/d may not be able to hold. According to the official interpretation of the Measures for the Implementation of Capacity Replacement in the
Cement and Glass Industry (2024 edition), the provisions on the approved capacity based on the diameter of cement rotary kilns should be abolished to promote the unification of the registered capacity and the actual capacity. In order to promote the unification of the registered production capacity and the actual production capacity, for the compliance production lines whose actual production capacity is greater than registered production capacity, the difference in production capacity can be made up according to the implementation measures, and the relevant procedures such as registration, environmental assessment and energy assessment can be improved. The actual production capacity referred to here should be the actual production capacity of the production line, which is different from the actual production capacity calculated according to the kiln diameter as mentioned before. However, there is still a certain degree of correlation between them, which has certain reference significance.
For a batch of small and large projects, the actual production capacity is greater than or even far greater than design capacity. In order to deal with this kind of fraud, the competent authorities had to insert the procedure of comparing the design capacity with the actual capacity calculated according to the kiln diameter and taking the smaller one. This is really a "landscape" line in the cement industry.
How to make up the difference in production capacity? Especially when there is a large gap, how can we really make up for it? Since the original design unit and Party a worked together to reduce the production capacity and turn the feasibility study into a batch study, the competent authorities are determined to standardize the production capacity management of the cement industry. In order to eliminate the serious impact of the two skins of record capacity and actual capacity on the seriousness of examination and approval, the honest management of enterprises, and the development ecology of the industry, enterprises with two skins of record capacity and actual capacity sho uld work together with the original design units to complete the production line scale and output plan requirements. Project demand analysis and output plan, project factor guarantee, production and operation plan, safety guarantee plan, investment estimation (purchasing capacity, preliminary work cost, capital, etc.), profitability analysis, financing plan, debt repayment ability analysis, financial sustainability analysis, ecological environment impact analysis, resource and energy utilization effect analysis, carbon peak and carbon neutralization analysis. Risk identification and evaluation, the main risks faced by the project and other contents are carefully studied, and the feasible research conclusion of how much capacity the project should supplement is put forward. After the production capacity is completed, the production line record capacity and the actual production capacity are unified. You can't just pat your forehead and fix it! It seems unconvincing whether the replacement scheme of the cement clinker production line project in
Guizhou Province to supplement 6833t/d production capacity can really achieve the unification of the registered production capacity and the actual production capacity!
