“城市煤气设计规范”中规定:民用灶具在0.5—1.5倍的煤气额定压力范围使用时,其燃烧热效率不应低于55％,燃烧废气中的一氧化碳含量不应高于0.05％(当过剩空气系数α=1时)。
The “City Gas Design Code” stipulates that when the civilian stove is used in the range of 0.5 to 1.5 times the rated pressure of coal gas, the thermal efficiency of combustion should not be lower than 55%, and the content of carbon monoxide in the combustion exhaust gas should not exceed 0.05% (when the excess air When coefficient α=1).
