“…A number of rotary kiln models has been proposed over the years and recent computational fluid dynamic models can be developed but all have their limitations (Barr, 1989;Bui, et al, 1995). Most assume isothermal conditions through the bed at any axial position (Majumdar, & Ranade, 2006).…”

“…A model of rotary kiln heat transfer, which accounts for the interaction of all the transport paths and processes to the rotary kiln from Casial, Deva Branch is presented in our paper. Information exchange and directions of transfer are shown in Figure 7 (Barr, et al, 1989). Two dimensional modelling is applied using finite element method.…”

“…The first approach, which is based on an experimental measurement campaign (Sonavane, 2009) and (Barr, 1989), this campaign is taken when the heat kiln is in rotation. The second approach is based on the numeric simulation which uses the same experimental load conditions.…”

“…24 A heat transfer coefficient correlation for free convection from a rotating cylinder recommended by Barr et al 26 was used in the simulation. Tscheng and Watkinson also recommend a heat transfer coefficient for the combined effects of conduction and convection between the bed and the wall, which was used in this work.…”

A one-dimensional numerical model was developed to simulate the effects of heat and mass transfer on the formation of oxides of nitrogen (NO x ) in a rotary kiln furnace for iron oxide pellet induration. The modeled kiln has a length-to-diameter ratio of approximately seven. The principal mechanism of heat transfer is radiation from the flame, which was described by the net radiation method. The well known Zeldovich mechanism was used to predict thermal NO x generation. Temperature fluctuations in the vicinity of the flame were estimated with a clipped Gaussian probability density function. The thermal energy and mass balance model equations were solved numerically. The model is capable of predicting temperature profiles and NO x production rates in agreement with observed plant performance. The model was used to explore the effects of process changes on the total NO x formation in the kiln. It was concluded that the gas temperature as well as the partial pressure of oxygen in the process gases controls the rate of NO x formation. Lowering the temperature of the kiln gases by increasing the secondary air flow rates requires simultaneously decreasing the pellet production rate in order to maintain the pellet temperatures needed for blast furnace conditions.
