This paper developed a stoichiometric thermodynamicnequilibrium model for biosolid gasification based on the biosolidnproperties, thermodynamic database, and equilibrium constants. Ifnthe calculation result showed that the quantity of char was negative,nthe quantity of char was put to zero, and the simulation was carriednout again. The model was first verified by woody gasification undernisothermal conditions, and the influence of a given temperature onnbiosolid gasification was simulated. The model further investigatednthe effects of different feedstock types, moisture contents, equivalencenratios, and reaction extensions on the adiabatic temperature, exergynefficiency, and syngas properties under autothermal conditions. Thenfour factors were all the main factors for adiabatic temperature.nThe exergy efficiency depended more on the operation conditions thannon the feedstock type. The H<sub>2</sub> concentration of the drynsyngas in biosolid gasification exhibited a curve both against thengiven temperature under isothermal conditions and against the moisturencontent under autothermal conditions.","PeriodicalId":522009,"journal":{"name":"Figshare","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"1753-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147889747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
