## Material and energy flows in rotary kiln-electric

Abstract. An energy saving strategy with two energy saving measures has been proposed for reducing energy loss in the rotary kiln-electric furnace (RKEF) for the smelting of ferronickel alloy. One of the measures is to recover the waste heat of exhaust gas from the rotary kiln for preheating and dehydrating the wet laterite ores in the rotary dryer.

## Rotary Kilns ScienceDirect

For a process to be efficient, we must get most of the energy into the material and later exhaust the rest. In addition to driving the process, heat transfer is also important for the control of the rotary kiln process. This chapter presents the classical heat transfer modes and their equations as they relate to the rotary kiln environment.

## Energy survey of the coal based sponge iron industry

2015-9-1  A material and energy balance around the kiln indicates that due to chemical reactions and combustion, heat generated inside the kiln is 272 GJ/h, which is the total theoretical energy required for the kiln. However, the actual energy consumption in a conventional plant in the kiln comes out to be 498 GJ/h. This value is 45.2% more than the theoretical energy consumption.
