Recently, the Office of Industry and Information Technology of a district in Northwest China announced the replacement plan of three cement clinker production lines to supplement production capacity and upgrade production capacity. One of the production lines will be implemented in two phases of capacity replenishment and upgrading. The Φ4.0 m kiln with a registered capacity of 2000 t/d in
Phase I is replaced by 500 t/d at a ratio of 1.5: 1, with a supplementary capacity of 333 t/d. After the supplement, the registered capacity rose to 2333 t/d. The source of 500 t/d capacity replaced is a bit of a "mouthful". First, in a capacity replacement plan approved in 2020, two production lines with Φ4.0 m kiln capacity of 2000 t/d and Φ4.0 m kiln capacity of 2500 t/d were combined to build a production line with Φ4.6 m kiln capacity of 4000 t/d. At that time, the kiln diameter was strictly linked to the production capacity, and the Φ4.6 m kiln could only be registered as 4000 t/d. The extra 500 t/d capacity index can not be abandoned, and it will be transferred to another capacity replacement scheme approved in 2020, which is also the capacity scheme of a new Φ4.6m kiln with a capacity of 4000 t/d production line. There are three transferors of production capacity of this production line. Among them is the 500 t/d. At that time, the replacement method did not have the condition that "the cement clinker production capacity used for the replacement of new projects could not be split and transferred", so the splitting of 2500 t/d for two new production lines was also compliant. Later, according to the announcement, the project has announced the capacity replacement plan but has not been implemented. According to the new replacement method, if the announcement of the capacity replacement plan has been completed and the project has not been started before the implementation of this method, the ignition and production shall be completed before the end of December 2026; if the project has not been completed, the capacity replacement plan will be invalid after January 1, 2027. The 500 t/d must be used before the end of next year to ignite and put into production, otherwise it will be abandoned. Therefore, it is urgent to use the 500 t/d quickly, and the most realistic way is to supplement the production capacity, which does not involve the construction content. Because they only need to replenish production capacity, they can quickly find a "husband's family" and "marry" out. In the process, it is better to reduce the amount of replacement than to draw water from a bamboo basket in the end! If you "marry" first according to 1.5: 1, the loss of 167 t/d will be regarded as "betrothal gift". The official announcement is called the replacement plan of supplementary capacity and upgrading capacity of 4333 tons per day cement clinker project (completed in two phases), so there is a phase (only) supplementary capacity project. According to the announcement of the
second phase, the second phase of upgrading and transformation project will be implemented on the basis of the first phase of supplementary production capacity. How to implement? The "husband's family" has two "sons" (two Φ4.0 m kiln production lines), based on the other "unmarried" 2000 t/d, the "married" 2333 t/d is packaged as a whole "dowry", which avoids the stipulation that "the cement clinker production capacity used for replacement of new projects can not be split and transferred". A new production line with Φ4.4 m kiln capacity of 4333 t/d is built by "combining two into one", which also meets the requirement of "the capacity replacement ratio of the same legal person in the same plant area is 1:1". With careful planning, the "loss" of production capacity indicators has been minimized, and the result is naturally happy! How can
this replacement scheme of supplementary production capacity and upgrading and transformation maximize the benefits in the implementation of the new replacement method. But how can we forget the new strict requirement that the new production line should reach the benchmark level of energy efficiency in the cement industry in the current edition of the Benchmark Level and Benchmark Level of Energy Efficiency in Key Industrial Areas, and that the environmental performance level should reach A level! According to the announcement, the energy consumption of the new line is 102.87 kgce/t, but the benchmark level of energy efficiency in the cement industry should be 100 kgce/t. Of course, there is no relevant statement that the level of environmental performance is to reach A-level!
