Abstract

Dorongan dunia untuk menurunkan emisi karbon mengakibatkan kewajiban co-firing untuk PLTU di Indonesia perlu diterapkan. Di sisi lain, jumlah sampah perkotaan juga terus meningkat seiring dengan pertumbuhan penduduk. Pembakaran solid recovered fuel (SRF) dapat menggantikan bahan bakar fosil dan meminimalkan jumlah sampah. Namun, SRF mengandung komponen klorin dan alkali yang dapat menyebabkan masalah terkait pengendapan abu pada permukaan boiler. Penelitian ini bertujuan untuk menyelidiki dampak aditif selama pembakaran bersama SRF dan batubara, khususnya dalam mengurangi kecenderungan pengendapan abu. Bahan bakar utama yang digunakan dalam penyelidikan ini adalah SRF dan batubara. Berbagai bahan aditif, termasuk senyawa berbasis aluminosilikat (Al-Si), aluminium (Al), dan magnesium (Mg), diuji efektivitasnya dalam mengurangi deposit abu, dengan berbagai skenario dosis aditif (0,10 wt% dan 1,00 wt%). Penelitian ini menggunakan kombinasi perhitungan teoritis, metode eksperimental, dan observasi perilaku peleburan abu. Hasil penelitian ini menunjukkan bahwa penggunaan aditif berbasis Al–Si dan Al pada dosis 0,10 wt% menghasilkan permukaan probe uji yang lebih bersih dan menghasilkan lelehan partikel abu yang lebih sedikit dibandingkan aditif lainnya. Oleh karena itu, penambahan aditif berbasis Al–Si dan Al pada dosis 0,10 wt% menunjukkan potensi yang menjanjikan untuk mengurangi masalah pengendapan abu selama pembakaran bersama campuran yang terdiri dari 15 wt% SRF dan 85 wt% batubara.

The world's push to reduce carbon emissions means that co-firing obligations for PLTUs in Indonesia need to be implemented. On the other hand, the amount of urban waste also continues to increase along with population growth. Burning solid recovered fuel (SRF) can replace fossil fuels and minimize the amount of waste. However, SRF contains chlorine and alkali components that can cause problems related to ash deposition on the boiler surface. This study aims to investigate the impact of additives during co-combustion of SRF and coal, particularly in reducing the tendency for ash deposition. The main fuels used in this investigation were SRF and coal. Various additives, including aluminosilicate (AlSi), aluminum (Al), and magnesium (Mg)-based compounds, were tested for their effectiveness in reducing ash deposits, with various additive dosage scenarios (0.10 and 1.00 wt%). This research uses a combination of theoretical calculations, experimental methods, and observations of ash melting behavior. The findings revealed that using Al–Si and Al-based additives at a dosage of 0.10 wt% results in cleaner test probe surfaces and fewer melting spots than other additives. Consequently, incorporating Al–Si and Al-based additives at a dosage of 0.10 wt% exhibits promising potential for mitigating ash deposition issues during co-firing of a mixture comprising of 15 wt% SRF and 85 wt% coal.
