    Nov 01, 2017 The exergy balance of the rotary kiln is calculated with the same equations as the calculation for the rotary dryer, and the results are shown in Table 2. One of the main exergy input for the rotary kiln comes from the bituminous coal (i.e. 54.33%) which is more than half of the total exergy input, similar to the energy proportion

    Bypass dust leaving the kiln system requires separate reporting: line022; CKD recycling remains within the mass balance. Thus, it does not need additional reporting. The mass flow of CKD Cement kiln dust leaving the kiln system (and crossing the red boundary in the diagram) needs to be accounted for additionally: line023

  • Material and energy flows in rotary kiln-electric furnace Material and energy flows in rotary kiln-electric furnace

    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
