Development of Numerical Simulation Technique for Coal Gasification on Entrained Flow Coal Gasifier (Modeling of Coal Gasification Reaction and Prediction of Gasifier Performance)

Water - Gas Shift Modeling of Coal Gasification in an Entrained - Flow Gasifier

Most of the reaction rates for the water-gas shift (WGS) reaction were obtained from experiments under simplified laboratory conditions with specific catalysts. A few of the reaction rates without using catalysts were obtained under supercritical (water) conditions, with the pressure much higher than those in a typical gasifier. In either case, it is not clear how the published reaction rates c...

Low-rank Coal Gasification Studies Using the Psdf Transport Gasifier

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...

Numerical Simulation of Quenching Process in Coal Gasification

This Master’s Thesis compares two computational fluid dynamics solvers: the commercial solver ANSYS CFX and the open source code OpenFOAM. Simple benchmark cases with compressible and incompressible flows are tested and compared. Thereafter the more complex process of quenching in coal gasification is simulated. This thesis work describes the simulation of a part of the coal gasification proces...
