Abstract

The purpose of this study is optimizing the air and fuel quantities at kiln considering design parameters of the cement plant by keeping adequate safety factors at each level of calculations to assure that neither production rate nor quality of the clinker vary. 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. The kiln has a capacity of 1000 ton-clinker per day. It found that the major heat loss is Heat losses by the kiln exhaust gas (2.33%), hot air from the cooler stack (7.28%), Radiation from kiln surfaces (11.71%). Some possible ways to recover the heat losses are introduced and discussed and they are Electricity generation, Heat recovery from kiln surface and Pre-heating raw material before the clinkering process.
