How gasifiers work

WebEntrained flow gasifiers operate with feed and oxidant in co-current flow and are the most commonly used form of gasifier for petroleum coke feeds. The residence time in these processes is short (a few seconds). The feed is ground to 200 μm or less to promote mass transfer and allow transport in the gas. WebIn co-current gasifiers, the fuel and gas move in the same direction, usually downward (downdraft gasifiers), but the movement can also be upward. • In countercurrent …

WebThe water vapour will flow downwards and add to the water vapour formed in the oxidation zone. Part of it may be reduced to hydrogen (see equation (b), paragraph 2.2) and the rest will end up as moisture in the gas. b) Pyrolysis Zone At temperatures above 250°C, the biomass fuel starts pyrolysing. WebWood gas is a fuel gas that can be used for furnaces, stoves, and vehicles. During the production process, biomass or related carbon-containing materials are gasified within the oxygen-limited environment of a wood gas generator to produce a combustible mixture. In some gasifiers this process is preceded by pyrolysis, where the biomass or coal is first …

Gasification is a process that converts biomass- or fossil fuel-based carbonaceous materials into gases, including as the largest fractions: nitrogen (N2), carbon monoxide (CO), hydrogen (H2), and carbon dioxide (CO2).
