摘　　要：基于39台家用燃气灶的甲烷排放检测数据,把燃气灶的运行状态分为开启段、稳定运行段和关闭段进行研究,得到结论如下:开启段甲烷排放量快速出现峰值并迅速衰减,稳定运行段甲烷排放量较低且稳定,关闭段甲烷排放量也快速出现峰值并衰减。关闭段甲烷排放量峰值、甲烷排放量均高于开启段,开启段、关闭段的甲烷排放量均高于稳定运行段。检测39台额定热负荷为3.2~5.2 kW嵌入式大气式双眼灶,开启段为1 min,稳定运行段为9 min,燃气灶的甲烷排放率为0.14%。Based on the methane emission test data of 39 domestic gas stoves,the operation of gas stoves is divided into opening section,stable operation section and closed section.The conclusions are as follows:the methane emissions in the opening section peak and decline rapidly,the methane emissions in the stable operation section are low and stable,and the methane emissions in the closed section also peak and decline rapidly.The peak methane emissions and methane emissions in the closed section are higher than those in the opening section,and the methane emissions in the opening section and closed section are higher than those in the stable operation section.39 embedded atmospheric double burner stoves with rated heat load of 3.2 to 5.2 k W were tested.The opening section was 1 min,the stable operation section was 9 min,and the methane emission rate of gas stoves was0.14%.
