For example, the limitations of incorporating heat absorption by the water wall and super-heaters and inferring thermal reciprocity between each reactor model/module. This paper proposes a novel modelling approach to address these limitations by incorporating an external model that marries the advantages of the zone method and Aspen Plus to the greatest extent. A steady state operation of a 0.3 MW atmospheric bubbling fluidized-bed combustor test rig was simulated using the developed modelling approach and the results were compared with experimental data. The comparison showed that the predictions were in agreement with the measurements. Further improvement is to be expected through incorporating more realistic zoned geometry and more complex reaction mechanisms. In addition, the developed model has a relatively modest computing demand and hence demonstrates its potential to be incorporated into process simulations of a whole power plant. date: 2018-10-01 date_type: published official_url: http://doi.org/10.1016/j.apenergy.2017.08.030 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1621361 doi: 10.1016/j.apenergy.2017.08.030 lyricists_name: Hu, Yukun lyricists_id: YHUDX81 actors_name: Hu, Yukun actors_id: YHUDX81 actors_role: owner full_text_status: public publication: Applied Energy volume: 227 pagerange: 168-179 issn: 0306-2619 citation: Hu, Y; Wang, J; Tan, CK; Sun, C; Liu, H; (2018) Coupling detailed radiation model with process simulation in Aspen Plus: A case study on fluidized bed combustor.
