Vegetable oil residues, which are often used for biogas production, are prone to fires. The decomposition and fire behaviors of four vegetable oil residues, namely rapeseed oil residue (ROR), peanut oil residue (POR), gingili oil residue (GOR), and soybean oil residue (SOR), were investigated using elemental analysis, thermogravimetry-differential scanning calorimetry-derivative thermogravimetry (TG-DSC-DTG), Fourier transform infrared (FTIR) spectrometry, and a cone calorimeter. Based on the TG-DSC-DTG results, ROR is the residue most susceptible to spontaneous ignition and complete decomposition. Further, although the FTIR results showed that the functional group compositions of the four residues are similar, according to cone colorimetry experiments, SOR has the lowest critical heat flux and the lowest peak value of heat release rate under an external heat flux.

经常用于沼气生产的植物油残留物容易着火。采用元素分析、热重-差示法研究了菜籽油渣(ROR)、花生油渣(POR)、姜油渣(GOR)和豆油渣(SOR)4种植物油渣的分解和燃烧行为。扫描量热法-导数热重法 (TG-DSC-DTG)、傅里叶变换红外 (FTIR) 光谱法和锥形量热仪。根据 TG-DSC-DTG 结果，ROR 是最容易自燃和完全分解的残留物。此外，虽然 FTIR 结果表明四个残基的官能团组成相似，但根据锥比色实验，
