The University of California in collaboration with West Biofuels, LCC, has developed an advanced thermochemical gasification system (5 ton/day) for the conversion of waste stream biomass for the production of bio-fuels and bio-energy. The “Pyrox” gasifier design is based on a dual-fluidized bed system operating at atmospheric pressure with air. Simulation of this gasifier was conducted with a n...

This paper presents the debugging test of biomass circulating fluidized bed gasifier in a rice mill factory Jiangsu Province. The main process system is reported. typical problems during period are analyzed, including blockage primary cyclone separator, loop seal, inventory leakage blast cap on air distribution plate, feeding tube coking, and large fluctuation pressure. Reasonable improvement c...

Abstract: Two modeling approaches, the scaling-law and CFD (Computational Fluid Dynamics) approaches, are presented in this paper. To save on experimental cost of the pilot plant, the scaling-law approach as a low-computational-cost method was adopted and a small scale column operating under ambient temperature and pressure was built. A series of laboratory tests and computer simulations were c...

In this study, the energy generation potential of forest residues in Mediterranean Region Turkey are determined by using different gasifier technologies. Gasification is one conventional waste to conversion technologies for production. Syngas, end product gasification process, generally used internal combustion engines, turbines and boilers as a renewable fuel. Energy was estimated up-draft fix...

A three-dimensional model of a circulating fluidized bed gasifier was developed, which uses continuous radial profiles of velocities and solids hold-up with regard to the description of fluid mechanics. A complex reaction network of sewage sludge gasification is included in the model. In the simulation calculations the influence of the axial location and the number of feeding points was examine...
