Abstract
Co-firing adalah merupakan proses penambahan biomassa pada pembakaran di PLTU sebagai pengganti parsial batu bara dengan tujuan untuk mengurangi pencemaran dan konsumsi energi fossil. Penambahan biomassa dalam proses pembakaran pasti juga akan mempengaruhi Performa dari pembangkit dan juga kebutuhan udara untuk melakukan pembakaran. Karena nilai kalor dari biomassa lebih kecil dari bahan bakar fossil dan kebutuhan udara dalam proses pembakaran akan mempengaruhi kinerja dari fan. Dalam Penelitian kali ini objek penelitian adalah PLTU unit 3 paiton yang akan diamati dan dianalisa performa pembangkit,daya dan kapasitas dari fan jika metode co-firing dengan bahan bakar batubara 4909 kcal/kg dan biomassa jenis wood pellet dengan variasi rasio co-firing 2,5%, 5%, 10%, 20%, 30% dan 40 % diterapkan di PLTU unit 3 paiton dengan menggunakan metode simulasi yang dilakukan dengan perangkat lunak cycle tempo 5.0. Hasil simulasi menunjukkan kesesuaian dengan teori.
Semakin besar rasio co-firing maka performa pembangkit pun mengalami penurunan. efisiensi pembangkit mengalami penurunan tertinggi pada pada rasio co-firing 60% batubara dan 40% wood pellet dengan nilai penurunan sebesar 0,739% dibanding kondisi baseline. Peningkatan NPHR tertinggi pada
kondisi rasio co-firing 60% batubara dan 40% wood pellet dengan nilai sebesar 0,759% dibanding kondisi baseline. Kemudian kapasitas dan daya dari primary air dan secondary air/forced draft fan mengalami peningkatan tertinggi pada rasio co-firing 70% batubara dan 30% wood pellet. Sementara itu, kapasitas dan daya dari induced draft fan mengalami peningkatan tertinggi pada rasio co-firing 60% batubara dan 40% wood pellet. ================================================================================================
Co-firing is a process of adding biomass to combustion at the PLTU as a partial replacement for coal with the aim of reducing pollution and consumption of fossil energy. The addition of biomass in the combustion process will also affect the performance of the generator and also the need for air for combustion. Because the calorific value of biomass is smaller than fossil fuels and the need for air in the combustion process will affect the performance of the fan. In this study, the object of research is PLTU unit 3 Paiton which will be observed and analyzed for generator performance, power and capacity of the fan if the co-firing method uses coal fuel of 4909 kcal/kg and wood pellet type biomass with variations in the co-firing ratio of 2, 5%, 5%, 10%, 20%, 30% and 40% are applied in PLTU unit 3 Paiton using a simulation method performed with cycle tempo 5.0 software. The simulation results show conformity with the theory.
The greater the co-firing ratio, the lower the performance of the generator. The efficiency of the generator experienced the highest decrease in the co-firing ratio of 60% coal and 40% wood pellets with a decrease of 0.739% compared to the baseline condition. The highest increase in NPHR was in the co-firing ratio of 60% coal and 40% wood pellets with a value of 0.759% compared to the baseline condition. Then the capacity and power of the primary air and secondary air/forced draft fan experienced the highest increase in the co-firing ratio of 70% coal and 30% wood pellet. Meanwhile, the capacity and power of the induced draft fan experienced the highest increase in the co-firing ratio of 60% coal and 40% wood pellet.
