Abstract

Penelitian ini bertujuan untuk mengkaji potensi penggunaan amonia sebagai bahan bakar tambahan dalam proses co-firing pada pembangkit listrik berbasis batubara. Co-firing dengan amonia menjadi topik penting dalam transisi energi bersih, mengingat amonia tidak menghasilkan emisi karbon dioksida (CO₂) selama pembakaran. Penelitian ini dilakukan dengan cara mengujicoba ammonia Co-firing dengan rasio ammonia hingga maksimal 3% terhadap batubara pada boiler tipe Subcritical Pulverized Coal & Tangensial Firing Boiler di sebuah PLTU berkapasitas 300MW.
Dari hasil ujicoba, didapatkan bahwa terdapat peningkatan efisiensi boiler ditandai dengan penurunan Nett Plant Heat Rate (NPHR) sebesar 109 Kcal/kwh dengan pembakaran stabil. Adapun emisi NOx yang dihasilkan terdapat kenaikan sebesar 0.104ppm dibandingkan dengan pembakaran batubara. Penelitian ini juga mengidentifikasi kondisi operasi optimal dan rasio co-firing amonia-batubara yang dapat digunakan untuk mengurangi dampak lingkungan tanpa mengurangi efisiensi sistem secara drastis. Hasil penelitian ini diharapkan dapat memberikan panduan bagi industri energi dalam menerapkan teknologi co-firing berbasis amonia untuk mencapai target dekarbonisasi.

This study aims to examine the potential use of ammonia as a fuel additive in the co-firing process in coal-fired power plants. Co-firing with ammonia is a key topic in the clean energy transition, given that ammonia does not produce carbon dioxide (CO₂) emissions during combustion. This study was conducted by testing ammonia co-firing with a maximum ammonia-to-coal ratio of 3% in a Subcritical Pulverized Coal & Tangential Firing Boiler at a 300 MW coal-fired power plant (PLTU).
The test results showed an increase in boiler efficiency, indicated by a decrease in the Net Plant Heat Rate (NPHR) of 109 Kcal/kwh with stable combustion. NOx emissions increased by 0.104 ppm compared to coal combustion. This study also identified optimal operating conditions and an ammonia-to-coal co-firing ratio that can be used to reduce environmental impacts without drastically reducing system efficiency. The results of this study are expected to provide guidance for the energy industry in implementing ammonia-based co-firing technology to achieve decarbonization targets.
