Combustion characteristics and gas interchangeability of natural gas with various compositions

In this study, an investigation into the gas interchangeability and combustion characteristics of natural gas with various compositions was performed. In order to suggest the appropriateness of gas interchangeability using the specific gravity(SG) and the Wobbe index(WI) values, combustion characteristics, which include incomplete combustion and flame lifting, were measured and observed for the upper and lower limits using the gas-oven as a domestic partial-premixed type appliance and the condensing boiler as a domestic premixed type appliance.
