In this study, an integrated system is developed for environmentally benign and efficient combustion of natural gas in domestic applications. For this purpose, natural gas is blended with biogas and renewable hydrogen to combat fossil fuel usage and greenhouse gas emissions released to the environment. Different blending ratios are analyzed with Aspen Plus software and combustion emissions are investigated. While CO2 emission and reactor heat rate are 6.48 kg/h and 27 kW when using only natural gas. These values decrease to 6.35 kg/h and 22 kW for 60%-40% natural gas biogas blend and 5.06 kg/h and 18 kW for 40%-40%-20% natural gas-biogas-hydrogen blend, respectively. In the case of this triple blending, the natural gas consumption reduces from 2.46 kg/h to 0.98 kg/h.
