Abstract:
A complete plant concept for the conversion of solid biomass to electricity and heat with an autothermal fluidized bed gasification and dry synthesis gas cleaning is developed. Plants with four distinct fuel capacities of 0.1, 1, 5 and 10 MW are further analyzed: firstlythe investment cost are estimated based on commercial offers for main machineryand secondly economic evaluation is performed. Results show that at least a plant with fuel capacity of 10 MW is cost competitive with actual commercial processes. Economic evaluation results in a break-even point of 3.3 MW fuel input, above which such plant is economically feasible. A high degree of heat sold to costumers is another prerequisite to obtain plant profitability.
