Research on the Gas Reburning in a Circulating Fluidized Bed (CFB) System Integrated with Biomass Gasification
N2O emissions from coal fired fluidized-bed combustion are approximately 30–360 mg/Nm, much higher than that from pulverized coal combustion (less than 30 mg/Nm). One approach to reduce the N2O is to reburn the biomass gasification gas in the coal-fired fluidized bed. In this paper, the effects of gasified biomass reburning on the integrated boiler system were investigated by both simulation an...
متن کاملMathematical Model of Biomass Product Using Gasification Reactor
The aim of this study is to design a new mathematical model biomass product with the help of the gasification reactor. This design will help in describing most of the internal parameters inside this process. This research also aims to study and analyze the kinetic reaction, mass and heat transfer for four zones of the gasification reactor. It has been found that the char concentration from ...
متن کاملGASIFICATION vs COMBUSTION OF WASTE/BIOMASS IN FLUIDIZED BED REACTORS
This paper presents a comparison of commercial fluidized bed gasifiers and combustors used to recover energy from municipal solid wastes and biomass. The work reported here is excerpted from four case studies prepared for the International Energy Agency’s Bioenergy Agreement, under Task 23 (Energy from Thermal Conversion of MSW and RDF, 1998-2000) and Task 36 (Energy from Integrated Solid Waste...
متن کاملSimulation of Biomass Gasification in Fluidized Bed Using Aspen Plus
Gasification is a thermo-chemical process to convert carbon-based compounds such as biomass and coal into a gaseous fuel. Among the various types of gasification methods, fluidized bed gasification is one which is considered as more efficient method than others as biomass is fluidized in a mixture of air/oxygen and steam. In the present study, a comprehensive steady state process model has been...
متن کاملArtificial neural network based modelling approach for municipal solid waste gasification in a fluidized bed reactor.
In this paper, multi-layer feed forward neural networks are used to predict the lower heating value of gas (LHV), lower heating value of gasification products including tars and entrained char (LHVp) and syngas yield during gasification of municipal solid waste (MSW) during gasification in a fluidized bed reactor. These artificial neural networks (ANNs) with different architectures are trained ...
