Title: Summary, biomass gasifier facility start-up tests - October and December 1995

Abstract

Shakedown testing of the biomass gasifier facility, located at the Hawaiian Commercial and Sugar Co. factory in Paia on the island of Maui, utilizing sugarcane bagasse, occurred in October 1995. Input and output streams for the process were sampled during three periods of steady-state operation in an air-blown mode. Additional tests were carried out in early December, 1995. Air and a mixture of air and steam were utilized as the fluidizing agent in the December operations, with two sampling periods occurring during air gasification and a single period under air-steam-blown conditions. This summary reports average values for the October test period, the December air-blown tests and the December air-steam tests (see following table). Details of individual tests are presented in the body of this report. During the October sampling periods, the average reactor temperature and pressure were 1545{degrees}F (840{degrees}C) and 43 psi (300 kPa), respectively. Bagasse from the sugar factory entered the dryer at a nominal moisture content of 45% and exited at 26%, wet basis. Wet fuel feed rate to the reactor averaged 1.2 ton hr{sup -1} (1.1 tonne hr{sup -1}). Average gas composition determined over the sample periods was 4% H{sub 2}, 10% CO, 18% CO{sub 2}, 3%more » CH{sub 4}, 1% C{sub 2}`s and higher hydrocarbons, and the balance N{sub 2}. The higher heating value of the gas was 100 Btu ft{sup -3} (3.7 MJ m{sup -3}). Condensable hydrocarbons (C{sub 6} and higher) in the output stream averaged 2.3% of dry fuel feed with benzene (C{sub 6}H{sub 6}) and naphthalene (C{sub 10}H{sub 8}) being the principal constituents. Carbon conversion efficiency, defined as the percentage of fuel carbon converted into gas or liquids, was estimated to be {approximately}96%.« less
