Abstract

A commercial scale (1240 MJ h-1) gasification system using bagasse and its briquettes for thermal application was developed. The system was tested at different airflow rates from 50 250 m³ h-1 (0.11 0.54 equivalence ratio). The biomass cosumption rate varied from 60 180 kg h'. The calorific value of the bagasse and its briquettes ranged between 17.8 and 18.0 MJ kg-1 and calorific value of gas was 4.44 MJ m3. The maximum gas production rate was 186 257 m³ hr-1. The efficiency reached a maximum of 63.34% for 30 mm briquettes at 200 m3 h-1 airflow rate at a consumption rate of 100 kg h-1.
