Literature Study Calculating Heat Balance And Thermal Eficiency in Rotayry Kiln at PT X
Keywords:
Rotary kiln, heat balance, thermal efficiencyAbstract
Rotary kiln is a device for burning raw meal products into clinker in a cement factory. Thermal energy is very influential on the rotary kiln in the clinker manufacturing process. The purpose of this final literature study is to know the process in a rotary kiln, to calculate the heat balance in a rotary kiln, to calculate the thermal efficiency of a rotary kiln. The method used is the comparison of data from the literature study with field data from research results. There are several supporting data to support the calculation, namely the specifications of the rotary kiln, the workings of the rotary kiln, the heat balance formula, and the thermal efficiency formula. Supporting data is used to perform quantitative analysis, namely calculating the heat balance and thermal efficiency. The results of the heat balance calculation data are Qin on an average of 343.1479703 Kcal/kg clinker and an average heat loss of 97.38451173 Kcal/kg clinker. The results of the calculation of thermal efficiency obtained an average thermal efficiency of 71.55%. So it can be said that the rotary kiln is still operating well, because the thermal efficiency value is still between 65%-75%, which is 71.55%.
