ABSTRACT:
A ceramic filter candle arrangement employs a plurality of filter candles held within a tube plate by hold-down weights, each having a flow path, and includes a conduit communicating with the flow path and protruding into the candle filter. A passage is formed between the conduit and the internal wall of the filter candle and leads to at least one exhaust port. In operation, the passage and the exhaust port allow controlled pressure wave leakage during gas pulse cleaning of the filter candle.
