Corrosion in coal gasification atmospheres

Corrosion of metallic materials by coal gasification atmospheres has been the subject of extensive study for over 20 years. While many alloys were found to be resistant to attack by high moisture content gases representative of fluidized bed gasifiers at temperatures up to 900 OC, good resistance could not be sustained for more than a few thousand hours as a result of changes in the structure a...

Alloy corrosion in a coal gasification system

The corrosion performance of alloys in coal gasification systems is of increasing industrial interest as more advanced coal-fired power generating systems are developed. It is necessary to consider the performance of candidate materials under likely exposure conditions to ensure that components have adequate lifetimes. Materials performance can influence the economic feasibility of these system...

Gasification: The Technology of Choice

The Power Systems Development Facility (PSDF) is an engineering scale demonstration of advanced coal-fired power systems and high-temperature, high-pressure gas filtration systems. The PSDF was designed at sufficient scale so that advanced power system components and the Department of Energy’s Clean Coal Roadmap program elements could be tested in an integrated fashion to provide data for comme...
