【摘要】 天然气因其高热值、低污染、使用方便等特点已经成为我国日常炊事使用率很高的一种燃气。天然气在气相燃烧的时候会生成一氧化碳(CO)、二氧化硫(SO2)、氮氧化物(NOx)、等气体,分别会在不同程度上对人体造成危害并对大气造成污染。本文通过实验对天然气燃气灶在不同火焰燃烧条件的烟气进行采集,并且通过烟气分析仪进行测量。分析数据得出天然气燃气灶在家用条件下,能够释放出大量一氧化碳(CO)、氮氧化物(NOx)等有害气体。甲烷的燃烧转化率低而产生的有害烟气浓度足以对人体造成很大伤害,并且会对大气造成严重污染。更多还原

【Abstract】 Natural gas is increasingly considered daily higher usage of fuel because of its high calorific value,low pollutions,convenient and other characteristics in China.The exhaust gas of natural gas in gas-phase combustion contains carbon mono-oxide,sulfur dioxide,nitrogen oxides etc.This is harmful to human body and cause atmospheric pollution in varying degrees.According to the experiments of natural gas under the conditions of different flame combustion of cooking stove,the exhaust gas was collected and measured in this paper.The data showed that cooking stove would produce large amounts of carbon mono-oxide,nitrogen oxides and other harmful gas.The conversion of methane is very lower so as to cause great damage to human body and pollution to atmosphere from the concentration of harmful gas.更多还原
