Air gasification of biogas-derived digestate in a downdraft fixed

Digestate is a byproduct from biomass anaerobic digestion process. Gasification of dried digestate to produce gasesous product might be a promising route. In this work, air gasification of digestate with high ash content was performed in a downdraft fixed bed gasifier at temperature varying from 600°C to 800°C and air equivalence ratio (ER

Experimental Study of Cotton stalks Gasification in a Downdraft

reduction (char gasification) overlap at a particular time along the gasifier[7]. Many researches have been conducted on downdraft gasifiers for diverse types of biomass to evaluate the gasifier performance and biomass capability of gasification. Jain [8] designed and tested an open core throat-less (stratified) gasifiers with internal diameters

Biomass gasification models for downdraft gasifier: A

1/10/2015 · Tinaut et al. developed a one-dimensional steady-state model for the gasification process in a fixed-bed downdraft biomass gasifier. The model takes into account almost all the phenomena that occur during the gasification process such as moisture evaporation and biomass devolatilization; heterogeneous reactions of the char with water vapor, carbon dioxide, hydrogen and oxygen; combustion of the volatile matter; homogeneous reactions such as water–gas shift reaction and reforming reactions

Experiment and numerical modeling of stratified downdraft

Downdraft models feature a combustion zone for volatile combustion, and the reduction zone exists underneath it. According to Reed and Das (1998) there are two different configurations of downdraft gasification, which are the Imbert downdraft and stratified downdraft versions. There has been research on flame propagation under downdraft conditions.


Gasification setup An atmospheric stratified downdraft gasifier with a height of 1.11 and 0.46 m in diameter was used in the experiment. Feedstock was fed through the top opening cap, while the material will hold on the steel grate in 42 cm diameter at the bottom. The air was flowing into the gasifier via throated holes into the gasification

This region serves the same function as the fuel hopper in the Imbert design.

Modeling product distribution of top-lit updraft gasification

Top-lit updraft (TLUD) biomass gasifiers produce relatively high yields of biochar when compared to other gasification units such as fluidized bed, downdraft, and updraft gasifiers (Nsamba et al. 2014). A top-lit updraft gasifier is a batch gasifier that is known to be ignited on the top layer of the biomass. Because of the flow of the biomass and the gasifying agent, it is also known as an
