Detailed Process Simulation of Pre-combustion IGCC Plants Using Coal-slurry and Dry Coal Gasifiers

Process Integration in Coal based Oxy-Combustion Power Plants

The oxy-combustion technology is ready for demonstration [1]. However, the energy penalty and investment cost related to CO2 capture are still too high to implement this technology in the power industry. The thermal efficiency penalty is currently around 10% points, and as discussed in [2] it is commonly expected to be reduced to below 6% points in the near future. Improvements on the sub-units...

Comprehensive Simulation of Coal Combustion in TFB

This paper reviewed models embedded in coal combustion simulation, and simulation of 200MW TFB (tangentially-fired boiler) is illustrated later. Comprehensive simulation of combustion will be a bridge between physical theory and practical engineering problems.

Cellular automata simulation of coal combustion

Simulation of coal combustion in the kinetic regime was developed using the formal support of cellular automata. The phenomenon was described as a process based on local interactions, with discrete time and space, at a mesoscopic scale level. In order to validate the method, simulation results were checked against both experimental data and traditional numerical models. Materials tested include...

IGCC Technology — Bituminous Coal IGCC With and Without CCS

Six Integrated Gasifi cation Combined-Cycle (IGCC) power plant confi gurations operating on bituminous coal were evaluated and the results are presented in this summary sheet. All cases were analyzed on the same basis, using a consistent set of assumptions and analytical tools. Each gasifi er type was assessed with and without carbon capture and sequestration (CCS). The individual confi guratio...
