3 MWth biomass gasifier associated with fossil combustion boilers

Summary: The project consisted of the design and construction of a demonstration scale fluid-bed gasification plant (3MW based on the LHV of the fuel). The plant was designed to gasify biomass wood pellets with air as a gasifying agent for using in thermal applications, specifically for co-combustion in large fossil fuel boilers (for instance in pulverized coal boiler). Once the plant was built, it was put into operation a sufficient number of hours to allow the adjustment and optimization of the plant to operate on wood pellets and olive stones. Other fuels from olive tree pruning (orujillo) and olive stone were also gasified. In the second phase, the design specifications to process other fuels and the possibility of using the gas in other applications, including electricity generation in engines, were established.
