How to Use the Heat of Combustion Calculator
Using the Heat of Combustion Calculator is a straightforward process, making it accessible to professionals and enthusiasts alike. Follow these steps:
- Enter Lower Heating Value (LHV): Input the lower heating value of the substance undergoing combustion.
- Enter Heat of Vaporization (Hv): Input the heat of vaporization associated with the substance.
- Enter Mass of Water (NH2O): Input the mass of water produced during combustion.
- Enter Mass of Fuel (NFuel): Input the mass of the substance undergoing combustion.
- Click “Calculate”: Press the calculate button to obtain the Heat of Combustion result.
The formula employed is HC = LHV + Hv * (NH2O / NFuel), where HC is the heat of combustion, LHV is the lower heating value, Hv is the heat of vaporization, NH2O is the mass of water, and NFuel is the mass of fuel. The result provides a quantitative measure of the energy released during combustion.
