Grate fired combustors. Grate-fired systems include both pile burners and spreader-stokers. Pile burners include the old-fashioned Dutch ovens(or Dietrich cells for bagasse and coffee grounds), Wellons cells, Lanb-Cargate wet cell or gasifier burners, and inclined grate systems. Spreader-stokers are distinguished by their feed mechanism, typically a windswept or pneumatic spout or paddle wheel located above the grate and the thin bed of fuel on the grate. The stoker mechanism spreads the fuel more or less uniformly across the grate. Grate fired systems may use flat or sloping grates, with inclined grates being the most severely sloping grate systems. Grates may be stationary or moving. They may be air cooled or water cooled. Ash removal from grates may be accomplished by moving arms, steam or air blowing systems, grate moving, or hand raking. Grate fired units may be refractory lined or waterwall furnaces, depending upon vendor and purpose.  1, record 2, English, - grate%2Dfired%20combustor

Reactors. The most widely applied reactors for gasification of biomass are the moving bed types and the fluidized bed types.... Moving bed-counter current. The moving bed reactor is a vertical shaft through which the biomass flows slowly downwards as a packed bed. The reactor has a gastight feeding system at the top and an ash removal system at the bottom. The moving bed reactor is used for biomass having dimensions of 1 to 10 cm. Three sub-types can be distinguished : cocurrent, countercurrent and cross-current reactors. The countercurrent moving bed gasifier is the most simple reactor type. The gas, produced in the reduction zone, leaves the reactor together with the pyrolysis products and the steam from the drying zone. The producer gas is rich in hydrocarbons and it has a temperature of about 400°C. The gas can be used for direct heating purposes. If it is to be used for electricity generation by internal combustion engines, it has to be cleaned thoroughly.  2, record 3, English, - countercurrent%20moving%20bed%20reactor
