Abstract

The paper describes the fundamental gasification characteristic of biomass and low rank coal mixture in gasification process using co-gasification methods as mixed fuel in fluidized bed gasifier furnace. The experiments focused in getting quality of gas produced from gasification processes of rice husks and low rank coal. The experiment on rice husks gasification found that every given fuel flow rate, the air fuel ratio increases with the rising of bed temperature. Higher operating temperatures lead to the lower heating values of gas product. More fuel needed to be burnt in order to attain higher temperature of the bed, however, the increase of operating temperature will increase in the efficiency of gasificationof rural society in development of PLTM/H to support rural electricity will work successfully.

Abstract

The experimental investigation and simulation model approach were carried out to investigate the behavior of the fine particles to ad­here on the layer of liquid on the wall in gas-solid two-phase flow. Polymethyl methacrylate having two different mean-diameters of 20 mm and of 50mm was used for measurement. By using continuous feeding sys­tem, the fine particles were entrained and mixed with the air in the duct. Experiment for solid particle gas with two-phase flow in room temperature was carried out to make a clear turbulent effect for particle adhering behavior to wall side having a high-viscosity liquid layer. These phenomena were also investigated by the simulation model which represented the experimental condition for two-phase flow and using k-ε two equation models for turbulent flow. The experimental result showed that adhered particle quantity depends on particle feeding rate. The result of simulation model also showed the same tendency. The relation of the various particles feeding rate and capture rate were also described.
