Abstract
A multi-field coupling numerical simulation calculates the natural gas flow, combustion, and gas–solid heat transfer processes in a trolley furnace using a computational fluid dynamics (CFD) method, coupled with a turbulence model (Realizable k-ε model), a combustion model (EDC), and a radiation model (DO). This work has investigated the characteristics of components, temperature, and velocity along the axial course of a high-speed burner burning natural gas. The flow field and temperature distribution of the combustion flue gas in a trolley-type heating furnace are analyzed. The surface temperature distribution and its internal temperature deviation of a three-slab stack in a trolley furnace are studied and the heating uniformity of the slabs is evaluated.
