| Abstract: | In order to obtain a calculation method in the design of the furnace of phosphoric acid, a two- zone model was proposed for the first time based on the radiative heat transfer in the furnace, which was divided into the combustion zone and the cooling zone along the path of gas. Furthermore, the calculation formulations were deduced. The predicted results by the model were in good agreement with experimental measurements. |
| Keywords: | furnace of phosphoric acid two-zone model radiative heat transfer |
