High-Temperature,High-Pressure Particulate Control with Ceramic Bag Filters.

摘要

The report gives results of bench-scale research indicating that fine particle control at high temperature and pressure can be achieved using barrier filtration by ceramic bag filters. Evidence supporting this contention includes: (1) 'blanket'ceramic fiber materials (felts) consisting of small diameter fibers (3.0micrometers) appear to be the most promising materials for high-temperature and -pressure applications because of their combination of good filtration performance and relatively high strength;and (2) accelerated media cleaning tests at high temperatures and pressures show that several ceramic filter structures are capable of surviving in excess of 50,000cleaning pulses while maintaining pressure drop at acceptable levels.
