Cement Glass Industry (2024 edition) for more than one month, it has greatly promoted the standardization of capacity management of existing cement clinker production lines. In explaining why the implementation measures for capacity replacement were revised, the new implementation measures said that through strict capacity identification, improvement of new project standards, simplification of cross-provincial flow procedures and other corresponding adjustments, the industrial layout adjustment and green low-carbon transformation were promoted, and the cement and glass industry was promoted to achieve high-quality development. In the interpretation of the main amendments, there are five items, the first and second of which are to tighten the requirements of cement replacement, improve the way of capacity verification, and promote the unification of registered capacity and actual capacity.
"Strict" or "stricter" should reflect the intensification of efforts to curb new capacity and strengthen capacity reduction. As far as the formulation of the capacity replacement plan is concerned, in the same case, the reduction of capacity through the plan formulated in 2024 should not be less than that of the plan formulated in 2021.
Recently, a province in southwest China announced a replacement plan for a cement clinker production line project with a daily output of 4000 tons.
Acceptance of supplementary capacity project: specification, model and quantity of main equipment: one Φ4.6x50.4m rotary kiln; design capacity: 4000 t/d; replacement (inlet) capacity: 1333 t/d; replacement ratio: 1.5: 1. What is the original design capacity of the
project? There is no publicity. According to the above data, it should be 2667 t/d. After investigation, the list of cement clinker production line published by the province only until 2022 shows that the design capacity of the line is 2500 t/d. The design capacity calculated according to the published capacity replacement scheme is 167 t/d more than design capacity published in the list. The new (documented) design capacity for the Supplemental Capacity Project shall be 3833 t/d
based on the design capacity shown in the schedule.
Transfer-out capacity project: specification, model and quantity of main equipment: one Φ3.5x56m rotary kiln; design capacity: 2000 t/d; used to replace transfer-out capacity: 2000 t/d.
2000 t/d is 1333 t/d according to the replacement ratio of 1.5: 1. According to the published data, the capacity account of accepting supplementary capacity projects and transferring capacity projects is "rolled flat".
If the design capacity of the transferred-out capacity project is 2000 t/d in 2021, the actual capacity is 1500 t/d according to the cement clinker capacity conversion table. If the actual capacity is less than registered or approved capacity, the replacement capacity of the supplementary capacity project shall be 1000 t/d according to the principle of determining the actual capacity and the specified replacement ratio of 1.5: 1. The design capacity announced in the
supplementary capacity project list is 2500 t/d, and now the supplementary capacity is 1000 t/d. The new (filed) design capacity shall be 3500 t/d. The design capacity announced
according to the capacity replacement plan in 2024 is 14% higher than design capacity calculated in 2021. Even 3833 t/d calculated according to the design capacity published in the list is 9.5% higher. The capacity accounts of the projects accepting the replenishment of production capacity and the projects transferring out of production capacity are not even. Is the
method strict or relaxed? It seems that there are still mistakes in the strict, can pick up the leak!
