Seeking help with circulating fluidized bed boiler issues
Thread Content
Our factory’s 75-ton circulating fluidized bed boiler: when the air volume used for fluidization was set to the design value of 6W5, the bed material still did not become fully fluidized. After checking the air nozzles several times, no issues were found. Experts, what could possibly be the cause of this problem? It’s urgent! ....
Keep pressing up to see if there’s a problem with the flow meter
What about the bellows pressure? Our small furnace is not equipped with a flow meter; when measuring the critical airflow at low temperatures, we determine the fluidization state by considering both the bellows pressure and the motor current. Pressure instruments are simpler and more reliable than flow meters. The installation of flow meters requires care. It is recommended that the poster check whether the current drawn by the blower exceeds the specified value (the motor’s rated current can be used as a reference); the pressure in the blower box generally does not exceed 4000 Pa, and fluidization occurs even at low temperatures.
