【 摘 要 】

For domestic gas cookers, the operating safety is the most important factor for end-users. The increases of CO emission with the variable natural gas constituents will seriously influence indoor pollution and affect human health. Response of CO emission of domestic gas cooker when interchanged by variable natural gas constituents was experimentally investigated from 8 kinds of Chinese domestic gas cookers while using 11 kinds of gas sources. The applicability of Weaver and AGA index on the CO emission prediction was also analyzed. It was found that well-adjusted gas cookers were flexible enough to give satisfactory performance without materially increasing CO emission. CO emission was found to be increasing with increasing Wobbe index of gas and Yellow-tipping. when considering the change of gas components, it can use the change of gas Wobbe Index to predict the CO performance of domestic gas cookers; Some limits should be imposed on Wobbe index of gas to be delivered nationally, so as to ensure no CO-related issues will be encountered.
