Abstract: Based on energy balance, a three-dimensional zone method mathematic model on conventional reheating furnace is set up. By coupling with heat flux of slab surface, the temperature fields of furnace gas zones and furnace wall zones is obtained by using the main variable-correction method, and slab temperature fields by finite difference method. Under typical working condition, the model is verified by the testing data. The influences of thermodynamic operating parameter and structural parameter on heat transfer process under steady working conditions without changing the productivity are quantitatively researched.

A semi-analytical approach on critical thermal states in water wall tubes of a subcritical drum boiler of a thermal power plant
TL;DR: In this paper, the critical situations in a furnace of a subcritical drum boiler were investigated and it was shown that by moving to higher altitudes of the investigated furnace, its water wall tubes were more sensitive to heat flux distribution, which consequently increased the possibility of dryness phenomenon and failure of the tubes.

Finite volume method for radiation heat transfer
TL;DR: In this paper, a finite-volume (FV) method for computing radiation heat transfer processes is presented. But the main ingredients of the calculation procedure were presented by Chai et al. The resulting method has been tested, refined and extended to account for various geometrical and physical complexities.
