| Technology Brief |
At the Amer Power Station in Geertruidenberg, a CFB gasifier plant has been constructed to produce gas as fuel for the Amer-9 600 MWe pulverized coal power plant, which is operated as large CHP plant. The project originally was to be started in 2000. The 83 MWth gasifier is to convert about 150,000 t/y demolition wood, replacing 70,000 t/y of coal. The gasifier is a low-pressure Lurgi CFB operating at 750 - 850°C. Originally, the raw gas was to be cleaned from particles, ammonia, and tars before entering the coal boiler. This has been modified to the much simpler system where the raw gas is partially cooled to approximately 450°C and particulate reduction by cyclones. During commissioning, practical problems mostly related to the fuel supply system. After modifications and successful trials in 2005, the gasifier had to be stopped. In the Dutch interpretation of the European WID (Waste Incineration Directive), the complete coal-fired plant was identified in December 2005 as waste incinerator because of the demolition wood fired gasifier. This situation has been solved November 2006 by allowing wood gas on the national “white list” of clean biomass fuels under certain conditions related to the concentration of 9 heavy metals. The gasifier typically operates 5000 h per year.
