在這項研究中，過氧化氫是在生物質燃燒的背景下引入的。通過熱重分析 (TGA) 結合傅里葉變換紅外光譜分析污泥、澳大利亞黑煤、棕櫚仁殼及其與不同濃度 H2O2 的混合物的燃燒特性。燃料及其各自混合物的著火溫度、燃盡溫度、可燃性指數 (C) 和燃燒特性指數 (S) 由 TGA 結果估計。最後，進行了模擬真實爐況的單顆粒燃燒實驗。 TGA 結果表明污泥熱降解發生在兩個不同的階段，而煤熱分解僅發生在一個階段。第一階段是由於 H2O2 的脫揮發分過程，第二階段是由於空氣與揮發物的氧化，第三階段是燃料中較重或複雜的成分。從 650 ℃下單顆燃燒的結果來看，只有摻有 70% 和 80% H2O2 的煤燃料錠才會發生氣相點火和燃燒。加入的高濃度H2O2 加劇了與揮發物的反應，使揮發物向早期燃燒。在給定的溫度下，在煤中加入 H2O2 在一定程度上降低了燃料錠的點燃時間。由於該研究考慮了具有三種不同主要特性的不同樣品，很明顯，與具有更多固定碳和灰分含量的樣品相比，具有更多揮發性物質含量 (PKS) 的樣品顯示出更好的結果。

In this study, Hydrogen peroxide is beings introduced in the context of the combustion of biomass. The combustion characteristics of sludge, Australian black coal, Palm Kernel Shell, and their blends with different concentrations of H2O2 are analyzed via thermogravimetric analysis (TGA) coupled with Fourier transform infrared spectroscopy. The ignition temperature, burnout temperature, flammability index (C), and combustion characteristics index (S) of the fuels and their respective blends were estimated from the TGA results. Finally, single-pellet combustion experiments were conducted simulating real furnace conditions. The TGA results show that sludge thermal degradation occurs in two distinct stages, whereas coal thermal decomposition happens in only one. The first stage is due to the devolatilization process of H2O2, and the second stage is due to the oxidation of air with volatiles, and the third stage, the heavier and/or complex components in the fuels. From the results of pellet combustion at 650 °C, gas-phase ignition and combustion only occurred for coal pellets blended with 70% and 80% H2O2. The high concentration H2O2 added escalated the reaction with the volatiles and made volatile matter combustion towards the early stage. Adding H2O2 to the Coal samples decreased the ignition delay time of the pellet to a certain extent at the provided temperature. As the study considered the different samples with three different dominating properties, it was evident that the sample with more volatile matter content (PKS) has shown better results compared with the sample having more fixed carbon and ash content.
