What are the hazards of slag leakage from the water-cooled air distribution plates in circulating fluidized bed boilers?
If slag leaks from the water-cooled air distribution plate into the water-cooled air chamber, it will block the passage of the primary air, increase the resistance to the flow of primary air, affect its velocity, and thereby impact the fluidization state of the entire bed. An increase in the pressure of the primary air system leads to an increase in the fan’s output, which can even exceed the rated value. The blower casing is prone to cracking due to the high pressure, resulting in damage to the equipment.
