Based on an industrialized demonstration, the biomass gasification technology applied in industrial boiler industry was studied in the paper. The operation characteristics and the energy consumption were investigated. Meanwhile, the effects on both the environment and the economy for the demonstration were analyzed. The result showed that Chinese redwood displayed the best capability in terms of the system operation characteristics compared with other biomass feedstock. Moreover, the energy consumption analysis presented that heat loss resulting from the exhaust gas, the recyclable cooling water and the equipment & pipeline accounted approximately for 16% of the total energy, which could be further saved for the system. Finally, the demonstration was proved to be largely environment-friendly and profitable by its low pollutant emission and high investment income. Furthermore, it was found that the sales price of the steam would be the main factor determining the economic benefits for other similar-scale projects.
