Abstract
A device for monitoring the hollow filter components employed to filter hot and dusty gases. The components are grouped inside a filter housing (1). The components communicate through supply lines (9) with collectors ( 10). The collectors convey the filtered gas away. The line supplying each group accommodates a lance (15). The lance injects a fluid for sweeping the components clean. A transducer (16) downstream of the filter components detects the pressure of the filtered gas in the line. A change in pressure reveals a malfunction.
