PFBC dust cake studies

The Westinghouse Electric Corporation, Science and Technology Center is developing an Integrated Low Emissions Cleanup (ILEC) concept for high-temperature gas cleaning to meet environmental standards, as well as to provide economical gas turbine life. The ILEC concept simultaneously controls particulate, sulfur, alkali, and other contaminants in high-pressure fuel gases, or combustion gases, at temperatures up to about 1700 degrees Fahrenheit in advanced, coal-fired, power generation systems. The overall objective of this program is to demonstrate, at a bench scale, the conceptual, technical feasibility of the ILEC concept for multi-contaminant control, and to provide test data applicable to the design of subsequent field tests. The current program objective is to conduct ceramic barrier filter testing under simulated PFBC conditions to deal with filter cake permeability and pulse cleaning issues that have been identified in recent PFBC filter field testing.
