NOVELTY - A biomass effective usage assistance system has biomass input part (1) where biomass are injected, apparatus registration part (2) which registers the intrinsic characteristic data, processing flow assembly department (3) which selects the equipments registered and assembles the processing flow of biomass and calculating part (4) which calculates the water quality of the wastewater produced when biomass is processed, generation amount of biogas, gas concentration, amount of energy recoverable from biogas, electric power generation amount and required running costs.    USE - Biomass effective usage assistance system for effective usage of biomass.    ADVANTAGE - Biomass effective usage assistance system can efficiently process biomass produced from biomass sources.    DETAILED DESCRIPTION - A biomass effective usage assistance system has biomass input part (1) where biomass such as sewage sludge, livestock farming excrements, scrap wood, organic refuse and other waste materials are injected, apparatus registration part (2) which registers beforehand the intrinsic characteristic data and has an equipment consists of preprocessor, anaerobic digester tank, dehydrator, heat exchanger, incinerator and generator, processing flow assembly department (3) which selects the equipments registered into the apparatus registration part and assembles the processing flow of biomass and calculating part (4) which calculates the water quality of the wastewater produced when biomass is processed, generation amount of biogas containing methane, carbon dioxide, hydrogen and hydrogen sulfide, gas concentration, amount of energy recoverable from biogas, electric power generation amount and required running costs.
