Integrated Gasification Combined Cycle and Pressurized Fluidized-Bed Combustion power systems have made it possible to use coal while still protecting the environment. Such power systems virtually eliminate the pollutants associated with coal-fired plants built before the 1970’s. Superior environmental performance and high system efficiency requires that gas stream cleanup be conducted under high temperature and high pressure process conditions. To realize this high system efficiency, particulate cleanup levels must meet gas turbine particulate tolerance limits. Discussed below are some of the particulate cleanup requirements and challenges for these advanced power systems. Also presented is the work underway to support particulate cleanup technology and the Clean Coal Technology (CCT) Program through pilot-scale testing and filter component development.
