| 摘要 |
This invention relates to a fluidised bed system in which the condition of the bed may be continuously monitored by vibration detectors. The system preferably comprises a container (1) having located in its walls a series of rigid rods (5). Each rod (5) has associated with it a vibration detector (9) which detects vibrations of the rods (5) caused by collisions with the bed particles and which transmits a signal to a comparator (13). By comparing signals from any selected combination of detectors (9) it is possible to gain an indication of the condition of the fluidised bed (4). <IMAGE> |
