Coal bends are crucial components in the infrastructure of thermal power plants, specifically designed for the pneumatic conveying of pulverized coal through the system from the pulverizers to the furnace. These bends are strategically positioned in the pipeline system to facilitate the smooth directional change of the high-speed coal-air mixture while minimizing wear and erosion which are common in such high-abrasion environments. Typically constructed from wear-resistant materials like ceramic-lined steel or other durable alloys, coal bends are engineered to withstand the harsh conditions of both the material being transported and the velocity at which it moves. Their design and material choice are critical to maintain efficiency, reduce maintenance costs, and ensure the longevity of the conveying system.
