3 Terms and Definitions
3.1 Bomb Heat of Combustion
The heat released per unit mass of sample when completely burned in a constant-volume bomb calorimeter filled with high-pressure oxygen, where combustion products include liquid water and dissolved nitric/sulfuric acids from nitrogen/sulfur oxides, with remaining gases (oxygen, nitrogen, carbon dioxide) in gaseous state.
3.2 Gross Heat of Combustion
The heat released per unit mass when combustion products include gaseous oxygen, nitrogen, carbon dioxide, nitrogen oxides, and sulfur oxides, with water condensed to liquid state.
3.3 Net Heat of Combustion
The heat released per unit mass when combustion products include all gaseous components and water vapor at constant pressure.
3.4 Energy Equivalent
The energy required to raise the calorimeter system temperature by 1°C (unit: MJ/°C).
4 Principle
A known mass of fuel is burned in a sealed oxygen bomb. The bomb heat of combustion is calculated from temperature observations before, during, and after combustion, with corrections for heat transfer and thermochemistry. The gross heat of combustion is derived by subtracting sulfuric/nitric acid formation heats from the bomb heat value, while the net heat of combustion further accounts for latent heat of vaporization.
5 Reagents/Materials
Warning: Oxygen strongly accelerates combustion (see Appendix A.1).
Warning: 2,2,4-Trimethylpentane is highly flammable (see Appendix A.2).
Unless specified, all reagents are analytical grade, and water is distilled/deionized.
5.1 Benzoic acid standard reference material (for calorimetry).
5.2 2,2,4-Trimethylpentane (≥99.75% purity).
5.3 Gelatin capsules.
5.4 Mineral oil.
5.5 Oxygen (free from hydrogen/flammable impurities).
5.6 Pressure-sensitive adhesive tape (cellulose-based, chlorine/sulfur-free).
