Abstract

ESP or electrostatic precipitator is a device used to capture particulate matter, such as dust, in exhaust gases using electrostatic principles. In the cement industry, ESP is commonly placed after the clinker cooler to clean the exhaust air from the cooling process, ensuring it is free from clinker dust. The clinker cooler is a device that cools down the clinker using air, reducing its temperature from an initial temperature of around 1450°C to approximately 100°C - 120°C. The exhaust air from the clinker cooler is then passed through the ESP at temperatures ranging from around 237°C to 311°C. Based on the temperature data, the exhaust air from the ESP has the potential for heat reuse for other processes, including as a heat source for drying rice husk, which is a common alternative fuel used in the cement industry and typically has a moisture content of around 25%-37%. The results of this design indicate that the exhaust heat from the ESP, with an input temperature of 275°C, is capable of drying rice straw pellets from a moisture content of 25% to 14.73% using a designed rotary dryer with a capacity of 21.6 t/h, a length of 41.58 m, and a diameter of 2.92 m. It is constructed using ASTM 283 C material with a thickness of 8.76 mm and is insulated with a 15.6 mm thick layer of aluminum foil.

Abstract

Condensate water is the result of condensing steam which has decreased in temperature and pressure due to losses from the environment. Steam trap used to separate water or dew from steam resulting from a decrease in temperature. This condensate water has a temperature of 50°C. Based on the results of condensate water testing from steam trap it has permissible criteria for boiler feed. In the existing conditions, the boiler feed water requirement is 500 liters/hour with a temperature of 25°C, while the water produced from steam trap of 230 liters/hour so that to be able to meet the needs of boiler feed water, a pump designed with a capacity of 50.6 liters/minute is needed. The purpose of this research is to design a pump to utilize steam trap water as boiler feed water. Materials are selected according to requirements and standards. Condensate water from the steam trap becomes the initial parameter for calculating Head, NPSH, Impeller Diameter, and Shaft Diameter. NPSH available must be greater than NPSH request to prevent pump cavitation, which can cause damage or loss.  Based on the calculations, the NPSH req value is smaller than the NPSH available, which is 4.62 m < 11.48 m. The total head is 7.97 meters, and the number of blades is 7. The design dimensions obtained are the impeller inner diameter of 29.47 mm, outer diameter of 72.58 mm, shaft diameter of 6 mm, casing diameter of 76.215 mm.
