In fluidized beds and suspension gasification, there is continuous relative motion of the discrete solid particles, while in fixed bed gasifiers there is much slower stratified motion of the solid bed as a whole, generally downward by gravity. The gas can then pass either in the opposite direction to the fuel(updraft or counterflow gasifiers)... or in the same direction(downdraft or coflow gasifiers).... While fixed bed coal gasifiers are updraft, biomass gasifiers can be either updraft or downdraft, depending on the purpose for which the gas is to be used. Updraft gasifiers can use very wet wood, but because the pyrolysis products are immediately cooled, the gas contains up to 30% of tar and oil.  1, record 2, English, - updraft%20gasifier

Le plus simple appareil de gazéification, à l'air (...), où les gaz montent à travers une couche de bois fixe disposée sur une grille (...) La combustion partielle et la gazéification du charbon de bois se produisent au point le plus chaud, c'est-à-dire sur la grille; les gaz dégagés traversent la couche de bois en cours de pyrolyse puis de séchage en emmenant de l'eau, des matières pyroligneuses et des goudrons. Il faut que ces gaz sortent à température assez élevée pour empêcher les condensations. Il faut également que ces gaz soient utilisés, brûlés immédiatement. Mais la difficulté due à la présence de goudrons subsiste.  1, record 2, French, - gazog%C3%A8ne%20classique

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 3, 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 3, 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 3, 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 4, English, - spouted%2Dbed%20gasifier

Low energy gas(LEG) is produced by air gasification processes where a portion of the input wood(about 20 percent) is combusted with air to provide process heat. LEG can be used to displace fossil fuels by retrofitting oil or gas-fired boilers, kilns, dryers and space heaters. In addition, it can be cooled and cleaned for use in internal combustion engines to generate shaft power or electricity. Due to the low energy content, economics dictate that the gas be used immediately and not piped great distances.  1, record 7, English, - low%20energy%20gas

Pyrolysis is the physical and chemical decomposition of organic matter brought about by the action of heat in the absence of oxygen... Most wood gasification systems commonly referred to as involving "pyrolysis" involve true pyrolysis as but one reaction in a multi-stage process with oxygen or air combustion being used to generate the necessary heat in another part of the reactor.  1, record 8, English, - wood%20gasification%20system
