OPERATION OF THE TRANSPORT GASIFIER™ AT THE PSDf

摘要

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 commercial scale-up. The PSDF is funded by the U. S. Department of Energy (DOE), the Electric Power Research Institute, Southern Company, Kellogg Brown & Root, Inc. (KBR), Siemens Power Generation, Inc. (SPG), Peabody Energy, Lignite Energy Council, and Burlington Northern Santa Fe Corporation (BNSF). Currently, the primary focus of the PSDF is research and advancement of the gasification process, with focus also on particulate removal and syngas cleanup systems. Gasification at the PSDF is based on the KBR Transport Gasifier™, which is an advanced circulating fluidized bed reactor designed to operate at considerably higher circulation rates, velocities, and riser densities than a conventional circulating bed. These conditions result in higher throughput, better mixing, and higher mass and heat transfer rates.
