Biomass gasification in a downdraft fixed-bed gasifier

BAGASSE FIRED BOILERS. By G. E. Gamble. "Bagasse" is the term applied to the waste fibres of sugar cane, after the sugar juices have been extracted in the mills. It consists of fibre and water, plus a certain amount of sugar juices. The amount of fibre and moisture varies considerably, being largely influenced by the nature of the soil, type of

US4376343A - Method and apparatus for drying bagasse

An outer cylindrical drum has an inner drum concentrically mounted therein in spaced relationship, to form coextensive outer and inner drying chambers that are connected to a common source of hot exhaust gases from a sugar factory boiler. Raw bagasse is first passed through the outer annular chamber to effect primary drying thereof, and then a portion of the primary dried bagasse is divided
