Title:
RARE EARTH ENERGY-SAVING ADMIXTURE FOR CEMENT KILN AND BLENDING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/197545
Kind Code:
A1
Abstract:
The present invention relates to the technical field of cement kiln energy saving and emission reduction. Disclosed are a rare earth energy-saving admixture for a cement kiln and a blending method therefor. In the present invention, under the condition of making no changes or making few changes to existing hardware devices, the addition amount of the rare earth energy-saving admixture is calculated by performing thermotechnical diagnosis on a production system, thereby reducing heat consumption of the production system, reducing nitrogen and sulfur emission, and saving the retrofitting and technical improvement costs of a large hardware device.
