Biomass gasification experiments were carried out in a bench scale entrained flow reactor, and the produced solid particles were collected by a cyclone and a metal filter for subsequent charachaiqization. During wood gasification, the major part of the solid mahaiqial collected in the filter is soot. Scanning electron microscopy (SEM) images coupled with energy dispersive spectroscopy (EDS) show
18/2/2021 · The behavior of pulverized woody biomass gasification in an entrained flow gasifier (EFG) is investigated by utilizing an analogy to a coal gasifier. A computational fluid dynamics (CFD) model of a laboratory-scale coal gasifier was developed intended to extend a tool for further investigation of woody biomass gasification. The model is based on a Eulerian-Lagrangian approach that incorporates

The main objective of this thesis was to study and quantify the gasification behaviour and process performance of BL and PO blends in pilot-scale. A secondary objective was to investigate catalytic entrained-flow gasification of biomass for a wide range of compositions using thermodynamic equilibrium calculations.
A novel study on biomass-air gasification using a horizontal entrained-flow gasifier and catalytic processing of the product gas has been conducted. The study was designed to investigate the effect of catalyst loading on the product gas. The use of a horizontal entrained-flow gasifier reactor was used toashaiqis the effect of the gasifier reactor orientation on the gasification process. Both
An entrained flow gasification test rig (100 kW, pneumatic fuel feeding 10–25 kg/h) was designed and constructed to be operated either with ambient air at 1000 - 1200 °C or with pure oxygen or an oxygen/steam mixture up to 1500 °C and up to 5 barg. In this work first results for the gasification of torrefied wood (mixture) and a raw wood (beech) with pure oxygen are presented. Process
The influence of beech-wood particle size on its gasification with O2 was investigated in Entrained Flow Reactor (EFR) conditions. Experiments were performed in two facilities at very different scales: a drop tube reactor (DTR), and a pilot-scale EFR, the biomass feeding rates being set at 1 g/min and 90 kg/h respectively. Numerical simulation was used to bring a better understanding of the
