Successful continuous injection of coal into gasification and PFBC system operating pressures exceeding 500 PSI - DOE funded program results
President Bush's energy program is focussed towards commercializing power production technologies that offer improvements in efficiency and reductions in emissions while utilizing the nation's most abundant energy reserve - coal. Gasification offers such benefits. To bring this technology to full commercial acceptance, the operational issue of feeding solid fuel into the pressure environment needs to be addressed. The DOE, through the National Energy Technology Laboratory, has funded research to develop the unique Stamet 'Posimetric Solids Pump' to feed coal into current gasification operating pressures. The project comprised design and testing to feed coal into 300 PSI and a second Phase for feeding into 500 PSI. The 300 PSI target was achieved in December 2003. In January 2005, the Posimetric feeder achieved continuous injection of coal into 560 PSI, exceeding the Phase 2 target. This paper presents a review and evaluation of the design, design optimizations and test results of the successful feeder. It also presents analysis of economic benefits to pump use and results from semi-commercial testing at gasifier operating test facilities, which should have commenced by the date of the Conference. 16 figs., 6 tabs.
