The integrated gasification combined cycle (IGCC) is a power generation technology which combines clean coal technology with a combined cycle. The system modeling is significant for design, operation and maintenance of the IGCC power plant. However, the previous IGCC modeling methods only contained a simplified compartment gasifier model, which is useful to consider the heat transfer and chemic...

The Power Systems Development Facility (PSDF) is an engineering scale demonstration of advanced coal based power systems, including the KBR Transport Gasifier, a hightemperature, high-pressure syngas filtration system, and a gas cleanup unit. Designed to be at a sufficient scale to test advanced power systems and components in an integrated fashion, the PSDF provides data necessary for commerci...

Biomass is the oldest form of energy used by human beings, mainly in the form of wood. It is a renewable source of energy and has many advantages from an ecological point of view. The direct combustion of biomass generates concern among environmentalists, as it is incomplete and inconsistent and may produce organic particulate matter, carbon monoxide and other organic gases. Biomass gasificatio...

In this paper design and fabrication of compact fluidized bed gasifier with increased gas – solid interaction is proposed for automotive vehicle. The aim of the design is generate a nitrogen (N2) free product gas with low tars and fines content. Firstly a compact size gasifier with fluidized bed is designed and after that it fabricated. Design was done with the help of CATIA design/modeling sof...

Kinetics-free equilibrium models can predict the exit gas composition of the biomass gasifier, given the solid composition and the equilibrium temperature, but they cannot be used for reactor design. Hence, there is a need to develop a combined transport and kinetic model which takes into account of the kinetics of homogeneous and heterogeneous chemical reactions, transport of volatiles produce...

Handling of bulk solids takes place in gasifiers either at the feed point or at the section of discharging waste and residues of the combustion and gasification. In large gasifiers, significant amounts of waste are expected to be produced, hence a proper gasifier design that allows an effective discharge of the waste from its bottom is essential for a smooth and reliable gasification. Poor gasi...

−− With the purpose of contributing to the energetic valuation of the solid wastes generated by the Colombian agricultural industry, a practical methodology for the design of a fluidized bed gasifier for rice husk on pilot scale was developed. The gasifier equipment, made up of a reaction chamber of 0.3 m of internal diameter and 3 m of overall height, was designed from theoretical and experime...

In this work, an experimental study of biomass gasification in different operation conditions has been carried out in an updraft gasifier combined with a porous ceramic reformer. The effects of gasifier temperature, steam to biomass ratio (S/B), and reforming temperature on the gas characteristic parameters were investigated with and without porous ceramic filled in reformer. The results indica...

Biomass mainly in the form of wood is the oldest form of energy used by humans. Biomass generally means a relatively dry solid of natural matter that has been specifically grown or has originated as waste or residue from handling such materials. The thermochemical conversion of biomass (pyrolysis, gasification, combustion) is one of the most promising non-nuclear forms of future energy. In the ...

Computational Fluid Dynamic (CFD) modeling applications of the biomass gasification process help to optimize the gasifier. This study aims to investigate the impact of several physical parameters on the behavior of gasification in a fixed-bed downdraft gasifier. To that end, the study presents a comparison of the results computed using the Fire Dynamics Simulator (FDS) model with experimental r...
