The World Congress on Engineering (WCE) 2017 was organized by the International Association of Engineers (IAENG) in London on 5 – 7 July 2017. The conference had the focus on the frontier topics in the theoretical and applied engineering and computer science subjects and received a total of 627 papers.

Tata Sutardi, a postgraduate research student within the Systems, Power and Energy Research Division of the School Engineering, supervised by Drs Manosh Paul and Nader Karimi, participated in this congress and his paper entitled “Numerical Modelling for Process Investigation of a Single Coal Particle Combustion and Gasification” has received a Certificate of Merit Award.

All the papers presented in the conference were judged on their originality, significance, correctness, and clarity. Tata’s paper for the above award was selected based on the reviewer reports and the evaluation score from the conference committee.

Abstract

Combustion and Gasification are commercial processes of coal utilization, and therefore continuous improvement is needed for these applications. The difference between these processes is the reaction mechanism, in the case of combustion the reaction products are CO2 and H2O, whereas in the case of gasification the products are CO, H2 and CH4. In order to investigate these processes further, a single coal particle model has been developed. The definition of the chemical reactions for each process is key for model development. The developed numerical model simulation uses CFD (Computational Fluid Dynamic) techniques with an Eddy Break Up (EBU) model and a kinetics parameter for controlling the process reaction. The combustion model has been validated and extended to model the gasification process by inclusion of an additional chemical reaction. Finally, it is shown that the single coal particle model could describe single coal particle combustion and gasification. From the result, the difference between single coal particle combustion and gasification can clearly be seen. This simulation model can be considered for further investigation of coal combustion and gasification application processes.
