Coal companies cannot ignore "dryness"
Pulverized coal consists of fine coal particles that are highly susceptible to oxidation when exposed to air, making them prone to spontaneous combustion. Additionally, when suspended in the air at certain concentrations, these particles can form explosive mixtures. As a result, ensuring the safety of coal powder during the drying process has become a critical concern in industries such as coal, power generation, steel production, and metallurgy. These important issues were among the key topics discussed at the Eleventh National Drying Conference held in Beijing from August 17th to 19th.
Drying equipment is primarily used to remove moisture from various materials through physical means. This technology is widely applied across multiple sectors, including chemicals, food processing, pharmaceuticals, and wood manufacturing. The widespread use of such equipment highlights its importance in improving product quality and operational efficiency.
The coal industry has a strong connection with the development of drying technology. For instance, drying and preheating coking coal can reduce the coking cycle by one-third and increase the production capacity of coke ovens by up to 5%. By removing moisture beforehand and shortening the coking time, the strength and ash content of the resulting coke can be more effectively controlled. This allows for the use of lower-quality coal to produce high-quality coke, enhancing resource utilization and cost efficiency.
The National Drying Conference, which takes place every two years, serves as a crucial platform for professionals in the drying industry to exchange knowledge, share innovations, and discuss challenges. Its primary goal is to enhance technical capabilities and promote sustainable growth within the sector. With ongoing advancements in technology and increasing demands for energy efficiency, the conference plays an essential role in shaping the future of the drying industry.
