What are the common faults of one-way air nozzles in circulating fluidized bed boilers?
Yes: 1. The fluidized pellets collide with and scour the outer wall of the air cap, causing wear to that wall; however, as long as the material of the air cap is of good quality, this wear occurs at a slow pace. 2. The fine particles of ash that leak into the water-cooled air chamber can enter the air ducts along with the primary air, thereby causing wear on the inner walls of the air nozzles. 3. The Γ-shaped directional air nozzles located on the bed surface may suffer severe wear as a result of the high-speed airflow from adjacent nozzles; this wear is not only severe but also occurs rapidly.
