National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Development of NDE technology for hot gas filters.

DE2001757549

Publication Date	2000
Personal Author	Ellingson, W. A.; Koehl, E. R.; Budzynski, B.; Carroll, J.
Page Count	10
Abstract	Hot gas candle filters are currently under development for hot gas particulate cleanup of advanced coalbased power systems. Ceramic materials systems are one option under development for hot gas filters and include oxide/oxide composites, clay-bounded SiC, recrystallized SiC, etc. One concern during plant shutdowns is the availability of reliable data of which to base decisions for resuing or replacing hot gas filters: another is the possibility of predicting remaining service life. The work in this product is directed toward developing nondestructive evaluation (NDE) technology that will allow detection and measurement of life-limiting materials characteristics such as cyclic fatigue from back-pressure pulsing, thermal shock, localized cracking, damage from local burning, and chemical attack.
