Development of an Indirectly Heated Wood Gasifier in a Technical Scale

摘要

An indirectly heated cocurrent fixed bed gasifier is presented for wet bio- mass in a technical scale. The concept and dimensioning of the 55 kW_th plant is presen- ted. Special emphasis is laid on the design of the reaction chambers and their indirect hea- ting. Further the feeding of the biomass is discussed. Wet forrestrial and agricultural residues and energy plants are planned to use as fuel.
