3 EVERY THING YOU NEED TO KNOW ABOUT HEAT BALANCE IN CEMENT KILN. 3.1 “Where does all that heat go?” Heat balances are the foundation for an engineer to identify the opportunities for possible heat savings. There are several areas where heat could possibly be saved to make a kiln operate more efficiently in matters of energy Energy Balance Of Cement Process. Mathematical modelling of the cement clinker clinker burning process from when kiln meal is fed into a cyclone preheater to discharge of the clinker from the cooler it is based on energy and material balances and consists of individual models for the plant components namely preheater calciner gas offtake bypass rotary kiln and grate cooler the models are Apr 02, 2019 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. The kiln has a capacity of 1000 ton-clinker per day. The input energy with various streams is calculated per kg clinker produced. The overall energy balance is summarized in Table 2.A component wise energy balance is similarly drawn using the information about the degree of calcination. The material entering the calciner is 30% calcined and the material leaving the calciner is 96% calcined [5]. The energy balance of a rotary kiln used for calcination of dolomite in a magnesium production company identified the kiln shell (26.35% of the input energy) and exhaust gases (18.95%) as the Apr 01, 2002 A component wise energy balance is similarly drawn using the information about the degree of calcination. The material entering the calciner is 30% calcined and the material leaving the calciner is 96% calcined .It is assumed that the calcination energy is uniformly distributed over the temperature range to calculate the calcinations energy in each component. Mass balance of the kiln system. 4. Raw material and coal compositions do not change. 5. Averaged kiln surface temperatures do not change. Based on the collected data, an energy balance is applied to the kiln system. The physical properties and equations can be found in Peray’s handbook [7]. mass and energy balance in cement kiln. Mass Balance of a Kiln System CKD leaving the kiln system and crossing the red boundary in the diagram needs to be quantified and requires additional reporting in the input methods A1 and A2 line510 or line655 Additional raw materials ARM which are not part of the kiln feed are not accounted for by the amount of raw meal consumed The fuel consumption is calculated analytically by establishing an energy balance over the kiln where the energy for calcination, drying as well as the heat energy of the in- and outgoing streams is accounted for. To calculate the heat energy of the different streams, polynomials were
