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.
