Abstract

ABSTRAK Boiler adalah alat berbentuk bejana tertutup yang digunakan untuk menghasilkan steam. Steam diperoleh dengan memanaskan bejana yang berisi air dengan bahan bakar. Boiler merupakan alat yang efisiensinya harus dipantau secara berkala. Pembakaran yang tidak sempurna merupakan penyebab turunnya efisiensi. Dari perhitungan efisiensi boiler tipe DK – D90 diperoleh hasil efisiensi saat menggunakan fuel oil tertinggi pada 27 Juli 2013 diperoleh 50,947 %, efisiensi terendah pada 21 Juli 2013 diperoleh 49,115 % dan efisiensi saat menggunakan fuel gas tertinggi pada 17 Nopember 2013 diperoleh 55,992 %, efisiensi terendah pada 15 Nopember 2013 diperoleh sebesar 54,133 %. Perhitungan dilakukan dengan metode langsung. Berdasarkan hasil perhitungan dapat diketahui bahwa boiler lebih efisien menggunakan bahan bakar gas. Efisiensi rata-rata saat menggunakan fuel oil 50,185 % sedangkan efisiensi rata-rata saat menggunakan fuel gas 54,907 % terdapat selisih sebesar 4,722 %. Boiler yang menggunakan fuel gas terdapat penghematan sebesar Rp 28.667.877/jam. Kata Kunci : Boiler , Efisiensi , Metode Langsung ABSTRACT A boiler is a closed vessel shaped tool that is used to generate steam. Steam is obtained by heating a vessel containing water with fuel. Boiler efficiency is a tool that should be monitored regularly. Incomplete combustion is the cause of the decline in efficiency. Type of boiler efficiency calculation DK - D90 results obtained when using fuel oil efficiency high on July 27, 2013 acquired 50.947%, the lowest efficiency was obtained on July 21, 2013 and 49.115% efficiency when using the highest fuel gas on November 17, 2013 acquired 55.992%, the lowest efficiency on November 15, 2013 amounted to 54.133% was obtained. Calculations carried out with the direct method. Based on the results of the calculations can be seen that the boiler more efficient use of fuel gas. The average efficiency when using fuel oil while the efficiency of 50.185% on average when using fuel gas 54.907% there is a difference of 4.722%. Boilers that use fuel gas savings of Rp 28.667.877/jam there. Keywords : Boiler , Efficiency , Direct Method
