Performance of High Temperature Air Blown Wood Biomass Gasification and Power Generation

High temperature air-blown woody biomass gasification model for the estimation of an entrained down-flow gasifier

“…Gasification processes using a fixed bed, fluidized bed and rotary kiln, in steam, oxygen or air-blown conditions have been developed or are currently under development (Yoshikawa and Moritsuka, 2006;Sugiyama et al, 2005;Chiaramonti et al, 2004). Most of these gasification processes are operated at temperatures of 1000-1200 K, but recent research is searching for gasification technologies at lower temperatures to achieve the highest cold gas efficiency.…”

Basic Study on Hydrogen-Rich Gas Production by High Temperature Steam Gasification of Solid Wastes

“…These fuels, distributed widely at low density, are not suitable for the power generation via direct combustion, whose efficiency tends to be low with small scale. Therefore, gasification technology has been studied by many researchers (1)(2)(3)(4)(5) in order to develop the high efficiency power generation system with small scale. Fuel cell power generation, which uses hydrogen as fuel, can achieve higher efficiency in small-scale since chemical energy is directly converted to electricity.…”

“…Hence, it is strongly required to develop the technology for hydrogen-rich gas production from solid wastes. Conventional gasification system (autothermal gasifier) uses air, oxygen or those mixtures with steam as a gasifying agent to supply heat by partial combustion of solid fuels (1)(2)(3) . Product gas of air-blown gasification is diluted by nitrogen, and the large-scale plant is favorable for oxygen-blown gasification from the viewpoint of economical feasibility.…”
