Description

Technical Field

[0002] my country is a major cement producer, accounting for approximately 70% of the world's total cement production in 2022, according to statistics. However, the cement industry is also a high-energy-consuming and high-emission sector. Statistics show that in 2021, the cement industry accounted for 6.5% of total industrial energy consumption and approximately 12.6% of the country's total carbon dioxide emissions.

[0003] Currently, the main method for assessing energy efficiency in cement enterprises is to establish an energy efficiency and carbon efficiency monitoring system within the enterprise. This system collects data on electricity, coal, water, and natural gas consumption at regular intervals for different processes, and then accurately calculates the enterprise's energy efficiency and carbon efficiency indicators according to relevant cement industry standards. While this method can accurately assess an enterprise's energy efficiency indicators, the high construction cost of the monitoring system makes it difficult to promote in practice. Some parameters are unavailable, making it impossible to accurately calculate the enterprise's energy efficiency indicators according to relevant cement industry standards. This is particularly true for the clinker calcination process, a high-energy-consuming and key process in the industry. If this process does not have a separate electricity meter, there is no data available, and in reality, electricity consumption data for any particular process is rarely available, making it difficult to obtain energy efficiency and carbon efficiency indicators for that specific process.
