Key Points

This research aims to establish a practical calculation method for the combustion properties of NG-H₂ mixtures.
Developed a calculation method for combustion thermal properties using a simplified gas composition.
Introduced the concept of equivalent fuel for stoichiometric calculations based on simple gas mixtures (CH₄, C₃H₈, N₂).
Constructed a system for calculating key combustion properties using thermal property data.
The proposed method showed fuel properties and exhaust characteristics closely matching original fuels across hydrogen blend ratios.

Implication

Proposes a calculation method for combustion properties in NG-H₂ mixtures, indicating a simplified approach.
