Given the significant contribution of building heating systems to combustion-related pollutant emissions, the application of advanced post-combustion technologies to improve exhaust gas quality and mitigate environmental impacts has become increasingly important. In this study, the performance of a dielectric barrier discharge (DBD) cold plasma reactor was experimentally investigated in two residential heating systems, including a cast-iron hot-water boiler and a wall-mounted gas water heater. The results demonstrated that the application of cold plasma technology reduced carbon monoxide emissions by 52% and 40% and unburned hydrocarbon emissions by 36% and 50% in the cast-iron boiler and wall-mounted gas water heater, respectively, while also enhancing the oxidation of combustion products. In contrast, nitrogen oxide emissions increased by 44% in the cast-iron boiler and 52% in the wall-mounted gas water heater. Although the findings confirm the high potential of cold plasma technology for reducing major combustion pollutants, they also identify the increase in nitrogen oxides as a critical challenge, highlighting the need to optimize reactor operating parameters to achieve simultaneous control of these pollutants.
