Numerical Multi-field Coupling Simulation of Multiple Slab Stacks Heated by Natural Gas Combustion in a Trolley Furnace

A multi-field coupling numerical simulationMulti-field coupling numerical simulation calculates the natural gas flow, combustionCombustion, and gas–solid heat transferHeat transfer processes in a trolley furnaceTrolley furnace using a computational fluid dynamics (CFD) method, coupled with a turbulence modelModel (Realizable k-ε modelModel), a combustionCombustion modelModel (EDC), and a radiation modelModel (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 distributionTemperature distribution of the combustionCombustion flue gasFlue gas in a trolley-type heating furnace are analyzed. The surface temperature distributionTemperature distribution and its internal temperature deviation of a three-slab stack in a trolley furnaceTrolley furnace are studied and the heating uniformity of the slabs is evaluated.
