Efisiensi Pembakaran Pada Ruang Bakar Boiler Untuk kebutuhan UAP 60 Ton/Jam Dengan Tekanan 20 Bar Menggunakan bahan Bakar Kayu dan Ampas Tebu

Abstract

Some affecting factors to the boiler efficiency are superheater pressure, feed water temperature, steam temperature, amount of fuel, and fuel heat value. Therefore, the boiler combustion chamber has the most important role in conducting combustion to produce heat energy used to boil water inside the pipe, with a capacity of 60 tons of steam/hour at 20 bars pressure by using fuel of wood and sugarcane bagasse. Then, it was obtained the Highest Heat Value (HHV) by 8,228.46 kj/kg bb and the Lowest Heat Value (LHV) by 7,566.47 kj/kg bb on sugarcane bagasse material whereas on wood material the HHV was 17,203.67 kj/kg bb and the LHV was 15,879.69 kj/kg bb. Thus, the Highest Heat Value (HHV) between a mixture of 25% wood and 75% sugarcane bagasse was 10,468.66 kj/kg bb and the Lowest Heat Value (LHV) of the mixture was 9,641.17 kj/kg bb.
