“…Thus, the validity of the reformer model is once again confirmed. In the previous studies [17], the validity of the reformer model is also confirmed in accordance with a steam-to-carbon ratio (S/C) of 1.8 and an oxidant-to-carbon ratio (O/C) of 0.33 for natural gas reforming. Table 2 summarizes the system parameters, flow sheets, and reforming methods considered in the present simulations.…”

“…In the system the hot fl ue gas exiting the afterburner was passed through a heat exchanger, where it preheats the air prior to entering the SOFC. Continued experimental investigations by Yen et al 5 showed that an optimal afterburner operation was obtained by assum-ing in the SOFC system the anode off gas temperature of 650 o C, cathode off gas temperature of 390 o C, fl ame barrier temperature of 700 o C and an excess air ratio of 2.0 at fuel utilization of 0.6. Under these conditions the afterburner operated in a long term continuous manner without the need for either cooling air or any additional fuel other than that provided by the anode off gas.…”

The aim of the present study was a numerical investigation of the efficiency of the combustion process of a novel concept burner under different operating conditions. The design of the burner was a part of the development process of a complete SOFC based system and a challenging combination of technical requirements to be fulfilled. A Computational Fluid Dynamics model of a non-premixed burner was used to simulate combustion of exhaust gases from the anode region of Solid Oxide Fuel Cell stacks. The species concentrations of the exhaust gases were compared with experimental data and a satisfactory agreement of the conversion of hydrocarbons was obtained. This validates the numerical methodology and also proves applicability of the developed approach that quantitatively characterized the interaction between the exhaust gases and burner geometry for proper combustion modelling. Thus, the proposed CFD approach can be safely used for further numerical optimisation of the burner design.

“…Considering these system features, to improve the power efficiency and reliability of the SOFC system, a variety of studies have been conducted on the system configuration and afterburner development of the H-BoP. For example, for afterburner development, Yen et al designed an afterburner with porous media and a reformer of the 1 kW SOFC system . In addition, a two-stage combustion burner was suggested, and non-premixed type burners were developed, , to improve the stability of the afterburner.…”

This study simulates the computational fluid dynamics (CFD) to explore the design optimization strategies of the solid oxide fuel cell (SOFC) afterburner. The CFD modeling with combustion is carried out with the eddy dissipation concept (EDC), applying a three-step rate-dependent reaction mechanism to predict the determining step of the combustion reactions by changes of the control and design parameters. The implemented CFD model is validated by comparison of the precedent experimental data and CFD studies. The simulation results examine the temperature distribution and reactivity of the fuel inside the SOFC afterburner with design parameters at start-up operation, such as the equivalence ratio and swirl number. In particular, the results of the parametric study show the possibility of design optimization to minimize the wall temperature and constraints to reduce the emission of toxicants (i.e., CO and NOx). The alternative burner design derived from the parametric study, when starting the SOFC system, has been proven to keep on the stable thermal stress and fuel reactivity, despite lowering the maximum wall temperature to 80.9%, compared to the conventional burner design.
