Calculation of energy and mass balance within an incinerator is a very important part of designing and/or evaluating the incineration process. This article describes a simple computer model used to calculate an energy and mass balance for a rotary kiln incinerator
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

process. In addition, Elkanzi [10] also established a model to evaluate the material and energy balance of the rotary kiln for GPC calcination and verified the result against actual industry operation data. From the perspective of thermodynamics, the calcination process of GPC in the rotary kiln is
Sep 01, 2015 An appreciable portion of the energy is being lost in the rotary kiln which has been shown through material and energy balance reported in Table 10, Table 11. The computation points out that 4.2%, 1.12%, 43.5% and 3.6% energy is lost through streams of sponge iron, char, waste gas and volatile matter, respectively
8 Slide 15 Lime Kiln Heat Rate • Heat rate is a measure of energy efficiency – Units are MM Btu/ton CaO or GJ/tonne CaO – Often stated as MM Btu/ton “product” • Typical range – 5 to 9 MM Btu/ton CaO – 5.8 to 10.5 GJ/tonne CaO – Lower is better Slide 16 Lime Kiln Energy Balance Components • Drying • Calcining : CaCO3 + heat CaO + CO2 • Losses – Heat loss through shell
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
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
Key words:Cement Plant, Rotary kiln system, Energy Balance, Heat Balance, Heat Recovery Abstract Waste Heat Recovery (WHR) is the process of recovering heat dischargedas a byproduct of one process to provide heat needed by a second process. So it is the capture and the use of
Apr 15, 2016 In this paper, thermal energy analysis of three zones of a lime production process, which are preheater, rotary kiln and cooler, is performed. In order to perform a proper quantitative estimation, the system was modeled using energy balance equations including coupled heat transfer and chemical reaction mechanisms
Apr 02, 2019 Analysis of Heat balance was used to determine the sources of heat loss from the kiln system. Based on the collected data, an energy balance is applied to the kiln system. The physical properties and equations can be found in Perry’s handbook. The reference enthalpy is considered to be zero at 0 C for the calculations
