Abstract
The estimation method of the interchangeability in a partial premixed appliance about various compositions of natural gases using equivalent gases, experimentally. The results of the experiment in which equivalent gases were used compared with those obtained in experiments in which natural gases were used; Images of flames, lift-off limits, CO emissions, and incomplete combustion indices in KS standard for the domestic gas range were considered. From the comparison, it was observed that the length and color of the flame of the equivalent gases were almost the same as those of imported natural gases. Further, in the case of gases with Wobbe indices greater than 51 MJ/$m^3$, the KS standard for lifting limits was satisfied. Furthermore, in the case of gases with Wobbe indices less than 56.3 MJ/$m^3$, the CO mole fractions are in the range 95-100 ppm. Hence, the range of Wobbe indices 51-56.3 MJ/$m^3$ was proposed to be the range for interchangeability from the points of view of lifting limits and incomplete combustion, as prescribed in the domestic gas range in the case of imported natural gases.
