Abstract
A method of monitoring filter components. The components are hollow and employed for filtering hot and dusty gases. They are accommodated in groups in a housing. Each group communicates through a single supply line with a filtered-gas line. The filtered-gas line conveys the filtered gas away. A sweeper is injected in the form of a gas into each supply line in cycles at higher pressure. The sweeping cycle is recorded. Measurement is carried out in the flow of sweeper and/or of filtered gas. The result of the measurement is compared with the record and an alarm released in the event of a discrepancy.
