| 摘要: |
| 同一管网引入不同来源的天然气已成为规划建设阶段的常见做法.不同天然气气源的组成可能存在差异,为了解不同燃气组成对民用燃烧灶具的CO排放的影响,避免大量终端用户的室内环境品质受到损害,对民用灶具的CO排放进行了实验研究.首先考察了中国12T天然气组成的分布并利用华白数相等与碳氢原子数守恒原则,确立了6组原组成天然气以及对应的三组分天然气,并测试灶具在每组燃气运行下的CO排放情况；对原组成天然气以及对应的三组分天然气的CO排放差异进行了讨论；在灶具上测试了以华白数和PN数为变化依据的不同三组分天然气. 实验表明:三组分天然气的CO排放与原组成天然气等价；气质参数华白数和PN数可以描述灶具在不同燃气组成下运行时的CO变化规律；在PN-W图上存在等CO排放线簇,可用于家用灶具使用不同组成燃气的CO排放预测,并以此为依据提出了一种确立CO排放界限气的思路. 对保障室内环境空气品质以及输配管网气源质量管理,都具有现实意义和实用价值. |

| Abstract: |
| It has become a common practice to connect the gas distribution system with various gas sources. However, constituent difference of natural gas may have negative effectgs on the end users. To understand the influence of different gas constituents on the CO emission of gas cooker and avoid the damage to the indoor air quality of a large number of end-users, an experimental study on the CO emissions of gas cooker was carried out. First, the distribution of 12T natural gas constituent in China was investigated, and six groups of the original natural gas and the corresponding three-component gas were prepared by using the principle of equal Wobbe number and the conservation of hydrocarbon atom number. The CO emission of the gas cooker under each set was also tested. Then the difference between be CO emission of the original natural gas and that of the three-component gas was discussed. Different three-component gases based on Wobbe number and PN number were tested on the cooker. Results show that the CO emission of the three-component gas was equivalent to that of the original natural gas. The gas quality parameters, Wobbe number, and PN number could be used to describe the variation of CO emission of gas cookers with different gas constituents. A series of CO isoline were revealed on the PN-W diagram, which can be used to predict the CO emission of gas cooker with different gas constituents. A method to establish the CO emission limit was put forward based on the diagram. The work of this paper is of practical significance and value for ensurance indoor air quality and gas source quality management of distribution network. |
