Pulverized coal dilute phase pneumatic conveying is a highly efficient and widely adopted technology for transporting fine coal powder over long distances through pipelines using a high-velocity gas stream. This method is particularly suitable for applications where the material-to-air ratio is relatively low, typically below 15 kg of coal per kg of air, ensuring that the particles remain suspended in the gas flow without settling. The system operates by introducing compressed air or inert gas at the inlet, which carries the pulverized coal from the feed point to the receiving vessel, such as a silo, burner, or reactor. The dilute phase approach is known for its simplicity, reliability, and ease of control, making it a preferred choice for many industrial processes, including power generation, cement production, steelmaking, and chemical processing.
One of the most significant advantages of dilute phase pneumatic conveying for coal powder is its ability to handle a wide range of particle sizes and moisture contents without clogging. The high gas velocity, usually ranging from 15 to 30 m/s, ensures that even the finest coal dust is effectively transported. The system can be designed with multiple pick-up points and discharge points, allowing flexible routing and distribution. Additionally, the absence of moving mechanical parts in the conveying line reduces maintenance requirements and extends equipment life. The use of inert gas, such as nitrogen, can also minimize the risk of dust explosions, which is a critical safety consideration when handling combustible coal powder.
Pulverized coal pneumatic conveying systems are extensively used in thermal power plants for feeding coal into boilers, in cement kilns for fuel injection, and in steel mills for blast furnace injection. The dilute phase method is especially suitable for applications where the coal powder needs to be transported over hundreds of meters, such as from a central coal mill to multiple burners. The technology also plays a vital role in coal gasification and chemical synthesis processes, where precise control of coal feed rate and distribution is required. By integrating with automated control systems, the conveying process can be continuously monitored and adjusted to maintain optimal performance.

In a recent project, Shandong Headpowder Engineering Co., Ltd. supplied a complete dilute phase pneumatic conveying system for a coal-fired power plant in Shandong, China. The system was required to transport pulverized coal from a central mill to four boiler burners located 150 meters away. The designed conveying capacity was 15 tons per hour with a conveying pressure of 0.3 MPa. By using a combination of venturi eductors and rotary airlocks, the system achieved stable operation with minimal wear and tear. The plant reported a 20% reduction in energy consumption compared to the previous mechanical conveying method, along with significantly lower maintenance costs. This case demonstrates the reliability and efficiency of Headpowder's coal powder pneumatic conveying solutions.
