A small-scale agricultural biomass CHP system — The SMARt project

A 5 kW_th, bench scale, bubbling fluidized bed gasifier (FBG) was designed and manufactured for biomass material gasification. It is an atmospheric air blown FBG unit that consists of four sections: a) biomass feeding section, b) air supply, control and preheating section, c) gasification facility and d) gas sampling and off line analysis section. This study presents a model for the simulation of the above biomass gasification system using various agricultural residues as feeding material. ASPEN PLUS process simulator was used. The validation of the model was performed by using experimental data obtained in the pilot gasifier funded by LIFE PLUS program. The biomass capacity of the small pilot unit was 1 kg/hr.
