A FEEDER FOR HIGH MOISTURE CONTENT COAL

摘要

A feeder for high moisture content carbonaceous material, especially lignite, comprises a housing (1) having an inlet (2) for introducing the carbonaceous material to the housing (1). The housing (1) has one or more converging sections (12a-12e) that are preferably of frusto-conical shape. A shaft (6) extends through the housing. Auger sections (8) define screw flights for transporting the carbonaceous material through the housing. Auger sections (8) define screw flights for transporting the carbonaceous material through the housing. Auger sections (8) do not extend through the converging sections (12a - 12e). At least one radially extending paddle extends from the shaft in each converging section. The feeder can be used to feed carbonaceous material to a high pressure environment, such as a boiler.
