Download or read book Development of a Pressurized Fluidized bed Biomass Gasifier to Produce Substitute Fuels written by and published by . This book was released on 1982 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Institute of Gas Technology (IGT) is conducting a program to convert forest and crop residues to substitute fuel in a pressurized fluidized-bed biomass gasifier. The process is designed for operation at pressures up to 2.17 MPa (315 psia) and temperatures up to 1255 K (1800°F). Various goals for synthesis or fuel gas processes are being pursued to develop an efficient process. Some of these goals are to maximize the throughput, the amount, and the quality of the gas, while minimizing both the amount of the feedstock preparation needed and the formation of condensible compounds that require by-product disposal and process wastewater treatment. The process development results obtained from fluidization, biomass devolatilization, and char gasification studies were used to design a 30.5-cm (12-inch) ID adiabatic fluidized-bed gasification process development unit (PDU), capable of handling up to 455 kg (1000 lb) of biomass per hour. The fluidized-bed gasifier performance is to be determined as a function of the standard operating parameters to develop a basis for recommending processes to produce either an industrial fuel gas for energy generation or a synthesis gas for methanol and ammonia production.

This book was released on 2015 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gasification is a process of producing fuel gas or synthesis gas from biomass using gasifier. The gas produced through this process particularly hydrogen will be utilized further as an input for power generation in order to produce energy. Due to the environmental concern and sustainability issues, energy from biomass has become one of the most promising renewable sources of energy. Current research points to improve the gasifier performance in order to elevate more economical product from the gasifier. For this purpose, the thermodynamic equilibrium model can be employed to predict the gas composition and to optimize important gasifier parameters for various kinds of gasifiers as well as utilizing various types of biomasses. In this work, the biomasses consisting of wood, rice husk, saw dust and empty fruit brunch are selected considering their low cost and availabilities as an abundant resource in Malaysia. These biomass sources are then served as the inputs for downdraft and fluidized bed gasifier for producing the hydrogen gas and through this study, the performance analysis in terms of the optimal parameters and gas output composition are then carried out. Here the air is used as an input reactant for downdraft gasifier and the fluidized bed gasifier is employing steam for the gasification process. In this work, the model validation is carried out first where the gas composition data obtained from thermodynamic equilibrium model show good agreement with experimental result from Zainal et al. (2001) for downdraft gasifier employing wood and Karmakar and Datta (2011) for fluidized bed gasifier using rice husk. Afterwards the performance analysis is performed to investigate the optimum parameters for downdraft and fluidized bed gasifiers. Based on this analysis, the optimum parameters obtained are at temperature 7700C with moisture content of 0.2 and steam biomass ratio 1.32, the hydrogen gas produced from wood, rice husk, sawdust and empty fruit bunch in downdraft gasifier is 16.38%, 17.02%, 16.30% and 50.12 % respectively, while in the fluidized bed gasifier is 38.75%, 50.00%, 73.30% and 71.77% respectively. The result of the performance analysis shows that the fluidized bed gasifier is more efficient than downdraft gasifier interm of hydrogen gas production.

Download or read book Biomass Gasification written by Malay Karmakar and published by LAP Lambert Academic Publishing. This book was released on 2011-01 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book describes fluidized bed gasification of biomass to generate hydrogen rich medium calorific value gas using steam as gasifying medium. Basic studies on steam biomass gasification process have been carried out in a laboratory scale bubbling fluidized bed gasifier and the endothermic heat is supplied by electrical heating. A mathematical model based on thermodynamic equilibrium has been developed to predict the behaviour of thermo-chemical fluidized bed biomass gasification. The subsequent chapters of the work has been devoted to develop a self-sustaining dual fluidized bed gasifier capable of producing medium calorific value gas. The dual bed system has two chambers; bubbling bed gasifier and fast bed combustor. A part of carbon from the gasifier is combusted in the adjoining combustor and the hot bed material from the combustor is circulated back to the gasifier for supplying necessary endothermic heat. The hydrodynamic design of the dual bed system has been carried out through cold model investigation. Based on cold model data, a pilot scale hot dual fluidized bed gasifier has been designed and developed and experiments have been conducted to generate data.
