Coal companies cannot ignore "dryness"
Pulverized coal consists of fine particles that are highly susceptible to oxidation when exposed to air and can easily self-ignite. Additionally, when suspended in the air at certain concentrations, it can form an explosive mixture. This makes the safe handling of coal powder a critical concern in industries such as coal, power generation, steel, and metallurgy. These issues were among the key topics discussed at the Eleventh National Drying Conference held in Beijing from August 17th to 19th.
Drying equipment is widely used across various sectors, including chemicals, food processing, pharmaceuticals, and wood manufacturing. Its primary function is to physically remove moisture from different materials, improving product quality and efficiency. The conference brought together experts and professionals who shared insights on the latest advancements in drying technology and its applications.
The coal industry has a strong connection with the drying sector. For example, drying and preheating coking coal can reduce the coking cycle by up to one-third and increase coke oven production capacity by around 5%. By removing moisture beforehand and shortening the coking time, the strength and ash content of the resulting coke can be better controlled. This allows for the use of lower-quality coal to produce high-quality coke, enhancing overall efficiency and sustainability.
Held every two years, the National Drying Conference serves as a vital platform for promoting technical innovation and improving the standards of the drying industry. It plays a crucial role in driving the industry’s sustainable and healthy development, ensuring that modern drying techniques meet the evolving needs of various sectors.
