Biomass gasification using dual fluidized bed gasification
Jan 20, 2021 · A DFB gasifier consists of two interconnected fluidized beds: (1) a bubbling fluidized bed (BFB) gasifier which converts biomass into raw syngas gas/product gas and, (2) a circulating fluidized bed (CFB) or fast fluidized bed (FFB) combustor (riser) which oxidizes the residual char in presence of an oxidizing or a fluidizing agent providing heat for the highly endothermic gasification reactions.
Frontiers | Comparative Techno-Economic and Exergetic
In this work, the techno-economic and exergy analyses of two gasification technologies with integration into heat and power combined cycles are presented: i). Circulating fluidized bed (CFB) and ii). Dual fluidized bed (DFB) systems. As feedstock, lignocellulosic biomass (sugarcane bagasse, SCB) was considered. The gasification process of the fluidized-bed systems (circulating and dual bed
Gasification - CPFD Software
CPFD Simulations of an Industrial-Sized Dual Fluidized Bed Steam Gasification System of Biomass with 8 MW Fuel Input In this study by Bioenergy 2020+ and the Technical University of Vienna, an industrial-sized dual fluidized bed biomass gasification system was simulated with Barracuda Virtual Reactor and compared with plant data.
H2-Rich Syngas from Renewable Sources by Dual Fluidized Bed
resource for chemical syntheses. The dual fluidized bed steam gasification technology provides the necessary heat for steam gasification by circulating hot bed material that is heated in a second fluidized bed reactor by combustion of residual biomass char. The hydrogen content in producer gas of such gasifiers is about 40 vol% (dry basis).
Application of CaO-Based Bed Material for Dual Fluidized Bed
Gasification of biomass is a suitable option for decentralized energy supply based on renewable sources in the range of up to 50 MW fuel input. The paper presents the dual fluidized bed (DFB) steam gasification process, which is applied to generate high quality and nitrogen-free product gas. Essential part of the DFB process is the bed material used in the fluidized reactors, which has

CO2 gasification in a dual fluidized bed reactor system
Oct 01, 2019 · Abstract. The use of CO 2 as gasification agent in the 100 kW th dual fluidized bed gasification pilot plant was investigated at TU Wien. For this purpose, steam was replaced stepwise by CO 2 as gasification agent. Softwood was used as fuel and olivine as bed material.
Flow Regime Identification in a Fluidized Bed Combustion Reactor
application of dual fluidized bed steam gasification system has increased during the past two decades , . The system consists of a dual fluidized bed reactor which is divided into two parts: gasification and combustion as shown in Figure 1. The gasification reactor or gasifier is a bubbling

fuels. This work focuses on the dual fluidized bed (DFB) CO 2/steam biomass gasification (see Fig. 1), which has a great potential in this field and is there-fore a main research topic at TU Wien since many years. So far, only steam was used as gasification agent in the DFB pilot plant at TU Wien. Therefore, the use of CO 2 instead of steam
Dual Fluidized Bed Steam Gasification of Coal and Pyrolyzed Coal
This system separates gasification and combustion as two fluidized bed reactors connected together by loop seals are used. The fuel (coal, char) enters the gasification reactor, a bubbling bed fluidized with steam, where drying, pyrolysis and heterogeneous char gasification take place at bed temperatures of up to 900 °C.
Dual fluidized-bed steam gasification of solid feedstock
Principles behind the dual fluidized bed gasifier This system separates the gasification zone and the combustion zone as two fluidized bed reactors, connected together by loop seals. The fuel, usually biomass, enters the gasification reactor, a bubbling fluidized bed fluidized with steam, where drying, pyrolysis and
