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...
متن کاملEffects of Turbulent Mixing and Controlling Mechanisms in an Entrained Flow Coal Gasifier
There is a large range of time and length scales of turbulent fluctuations in an entrained flow coal gasifier. To figure out the turbulent effects on coal gasification processes and the controlling mechanisms of different regions in an entrained flow coal gasifier, the characteristic time and length scales for all major processes are estimated.On the basis of the comparisonbetween the length/ti...
متن کامل3-D CFD Modeling for Parametric Study in a 300-MWe One-Stage Oxygen-Blown Entrained-Bed Coal Gasifier
Three-dimensional computational fluid dynamics (CFD) modeling of the gasification performance in a one-stage, entrained-bed coal gasifier (Shell Coal Gasification Process (SCGP) gasifier) was performed, for the first time. The parametric study used various O2/coal and steam/coal ratios, and the modeling used a commercial code, ANSYS FLUENT. CFD modeling was conducted by solving the steady-state...
متن کاملLow-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...
متن کاملStudies on Co2 Gasification Reactivity of High Ash Indian Coal
Coal is a prime energy source in India and will continue to play its role for coming several decades. However, our indigenous coal suffers from high ash content and present coal based conventional power generation technologies have several drawbacks such as, lower efficiency, environmental loading and damages thereof. Herein the importance of gasification lies because coal gasification is a mea...
