Updraft Gasifier. The updraft gasifier, also called a counter-current gasifier, is a type of fixed bed gasifier which can use solid biomass having moisture content up to 60%, low volatile matter, and high ash content up to 25%. Some of the advantages of the updraft gasifier are as follows (Ayyadurai, Schoenmakers, and Hernandez 2017). 1.

Such units were mass produced during World War II by many European automotive companies, including General Motors, Ford, and Mercedes-Benz. These units cost about $1500 (1985 evaluation) each. However, after World War II began in 1939, it took six to eight months before factory-made gasifiers were generally available.

<h3>Updraft Gasifiers</h3>

Updraft Gasifiers

In updraft gasifiers, gas is drawn out of the gasifier from the top of the fuel bed while the gasification reactions take place near the bottom. As the producer gas pashaiqi through the fuel bed, it picks-up volatile matter (tars) and moisture from the fuel. Therefore, the gas from the updraft gasifier contains condensable volatiles.

Dec 14, 2017 · There are three major kinds of fixed or moving bed gasifiers which are updraft gasifier, downdraft gasifier, and cross-draft gasifier. These names are given based on the directions of the flows of the fuel and the oxidant in the gasifier. Fixed bed gasifiers are suitable for small-scale application up to 10 MW.

Gasification-based proceshaiqi for power production charachaiqistically result in much lower emissions of pollutants compared to conventional coal combustion. This can be traced to the fundamental difference between gasification and combustion: in combustion, air and fuel are mixed, combusted and then exhausted at near haiqipheric pressure, while in gasification oxygen is normally supplied to the

Low density feedstock gives rise to flow problems and excessive pressure drop. High ash content coal also gives more problem with this kind of gasifier than updraft gasifier. Other disadvantage is it gives lower efficiency, since there is no provision internal exchange compare to updraft gasifier. The product stream also has low calorific value.
