Gasification is a thermal process to convert solid fuel into gasified fuel by non-stoichiometric, partial combustion.... The most established gasifier system is the down-draught gasifier. It produces an almost tar-free gas and can be constructed on a relatively large scale compared to other systems. Its disadvantage is the requirement for fuel preparation, which must be well cut, uniform wood or charcoal, with a moisture content not greater than 20%.  2, record 1, English, - downdraft%20gasifier

The "downdraft" (or coflow) gasifiers ... used widely during World War II produce very little tar and oil and are much more practical in small sizes for producing clean gas. Air (oxygen) is introduced at nozzles or tuyères which form a complex reaction zone not amenable to scale-up or simple analysis.  3, record 1, English, - downdraft%20gasifier

[...] gazogènes [...] dans lesquels l'air est introduit sous la zone de combustion. La chaleur dégagée par la combustion produit la pyrolyse ou la distillation du bois placé au dessus, mais les pyroligneux et les goudrons produits sont contraints à descendre, à passer à travers la zone de charbon de bois en ignition; ils sont donc craqués, réduits à l'état de CO + H₂ essentiellement. Il n'y a pratiquement plus de pyroligneux, ni de goudron.  2, record 1, French, - gazog%C3%A8ne%20%C3%A0%20tirage%20invers%C3%A9

spouted bed gasifier.... a single-chamber air-fed gasifier operated on a cyclical basis, to yield a high calorific-value gas essentially uncontaminated by carbon dioxide or nitrogen. Wood chips or wood pellets are fed on top of a bed of hot sand in the reactor, and are then mixed by spouting the bed using steam. Some gasification occurs during this phase, but most takes place during the ensuing "cooking" phase during which the bed is static. When the temperature has fallen to a suitably low value air is admitted to burn the char and raise the temperature of the sand to its original value. Wood is then added to begin a new cycle.  1, record 2, English, - spouted%2Dbed%20gasifier

Forest biomass projects include a joint venture with Omnifuel Gasification Systems Ltd for fluidized bed reactors, demonstrated at Hearst, Ontario on wood waste at the 84 GJ/hr scale. Similar technology using a pressurized oxygen gasifier is the basis for a partnership with Nouveler Inc. of Québec.  1, record 3, English, - pressurized%20oxygen%20gasifier
