Combined molten carbonate fuel cell and gas turbine systems for efficient power and heat generation using biomass

When used in combination with turbines, fuel cells can produce from 55 to 90% of the electricity of the system while turbines produce the remainder. Fuel flexibility enables the use of low-cost indigenous fuels, renewables, and waste materials. The characteristics of gas from biomass gasification may vary significantly. Most real systems cannot be modeled exactly. Errors arise from unmodeled or unknown parameters. From another point of view, robust control incorporates the varying or uncertain parameters of the model. The advantage of this uncertainty representation is that it provides a good representation of the uncertainty arising in many real control problems. (C) 2003 Elsevier Science B.V. All rights reserved.
