文摘

A simple approach is presented for the early detection of defluidization in a bubbling gas-solid fluidized bed. The new approach relies on the simultaneous monitoring of temperature and pressure signals. It effectively predicted the onset of agglomeration minutes to hours before complete defluidization. It was robust with respect to the changes in gas velocity, operating temperature, and bed inventory.
