Producer gas from citrus wood fuels irrigation power unit.

A 90-hp diesel engine operating a citrus irrigation system was converted to run on a dual-fuel mixture utilizing producer gas from citrus wood chips as the main fuel source. A chip feeder mechanism, gasifier, filter system and control unit were designed to meet typical irrigation power requirements. Blighted, unproductive and dead trees removed near the irrigation site were used for chipping. Data on chip moisture content, fuel analysis, drying rate and fuel/tree weight are presented but labour and equipment costs were not determined. 14 references.
