Abstract

Seiring dengan kemajuan teknologi keramik dan banyaknya permintaan konsumen maka banyak didirikan pabrikpabrik yang memproduksi keramik seperti PT. Keramik Diamond Industries. Penggunaan energi pada mesin kiln ini meliputi energi untuk proses pembakaran. Biaya yang dikeluarkan untuk konsumsi energi pada sebuah pabrik keramik berkisar 30 % dari total biaya produksi keramik (Erlin Tanoyo, Sekjen ASAKI). Jika biaya untuk konsumsi ini dapat ditekan maka keuntungan perusahaan dapat ditingkatkan. Oleh karena itu diperlukan analisis termal untuk mengetahui berapa besar beban termal yang terjadi pada mesin kiln tersebut, banyaknya konsumsi LNG yang digunakan dan berapa besar efisiensi yang dapat diperoleh. Dari data operasi PT. Keramik Diamond Industries diperoleh laju alir massa keramik 5463,82 kg/jam, massa alir LNG 52,856 kg/jam, speedy cooling air 505,566 kg/jam dan massa alir final cooling air 1013,389 kg/jam. Untuk mengetahui pengaruh massa alir keramik dan LNG terhadap heat losses yang terjadi dan efisiensi kiln, dilakukan analisis pada saat massa alir keramik 5124,133 kg/jam, 5224,933kg/jam, 5160 kg/jam, 5494,933 kg/jam dan 5463,82 kg/jam. Analisis dilakukan dengan konservasi massa dan energi pada Kiln. Untuk analisis perpindahan panas kiln dibagi menjadi 5 zona yaitu zona prekiln, preheating, firing, speedy cooling dan final cooling dengan panjang kiln 84 m. Analisis termodinamika pada kiln di PT. Keramik Diamond Industries menghasilkan efisiensi termal 39,33% dengan heat losses berupa gas buang sebesar 506,469 kW dan heat losses ke lingkungan sebesar 65,09 kW. Analisis perpindahan panas untuk menaksir heat losses yang terjadi yaitu sebesar 62 kW, heat losses tertinggi berada pada zona firing yaitu sebesar 34,64 kW. ===================================================================================== Along with advances in ceramic technology and costumer demand increased so that many factories which produced ceramic established like as PT. Keramik Diamond Industries. Energy used for kiln machine including enegy for combustion process. Cost of the energy comsumption for ceramic factory was about 30 percent of ceramics production total cost (Erlin Tanoyo, general secretary of ASAKI). If the cost of energy consumption for ceramic production can be decreased, it will be made profit for company increased. Because of that, needed to know how much thermal load which happen in the kiln machine, how much LNG consumption, and how much efficiency that we can get. According on operation data of PT. Keramik Diamond Industries, can be obtained mass flow rate of ceramic was 5463,82 kg/h, mass flow LNG was 52,86 kg/h, speedy cooling air 505,566 kg/h and mass flow final cooling air was 1013,389 kg/h. To determine the influence of the ceramic mass flow and LNG for heat losses and kiln efficiency, analysis at the time of the ceramic mass flow was 5124,133 kg/h, 5224,933kg/h, 5160 kg/h, 5494,933 kg/h, and 5463,82 kg/h. Analysis conducted by mass conservation and energy on the kiln. For kiln analysis devided into 5 zones there was prekiln zone, preheating zone, firing zone, speedy cooling zone, and final cooling zone which has 84 m long. Analysis of thermodynamic for kiln in the PT. Keramik Diamond Industries obtained 39,33% efficiency thermal with heat losses in the form of flue gas was 506,469 kW and heat losses to the surrounding was 65,09 kW. Heat transfer analysis to determined heat losses which happened was 62 kW, highest heat losses was located in firing zone was 34,64 kW.
