一、前言 在城市煤气供应规划设计中,“高峰系数”是很重要的基础数据。它既反映了煤气耗量的不均匀情况,又直接关系到工程经济效果与用户使用要求。影响高峰系数的因素很多,如气候条件、地理环境、工业与民用用气比例、工作班次、土产与生活用气设备配置情况以及居民生活水平和生活习惯等等。这些因素,从理论上是无法推算出来的。只有经过实地测定或调查,并加以科学地整理才能得到。 为了获得具有实际应用价值的高峰系数,对北京地区某城市煤气调压站的测定记录,进行了分析整理,以作为论证时的参考依据。
I. Preface In the city gas supply planning and design, “peak factor” is an important basic data. It not only reflects the uneven gas consumption, but also directly related to the engineering economic effects and user requirements. There are many factors that affect the peak factor, such as climatic conditions, geographical environment, proportion of industrial and civilian gas use, work shifts, allocation of indigenous and domestic gas appliances, and living standards and living habits of residents. These factors cannot be theoretically derived. It can only be obtained after field surveys or surveys and scientific sorting. In order to obtain the peak value with practical application value, the measurement record of the gas pressure regulating station in a certain city in Beijing area was analyzed and collated to serve as a reference for the demonstration.
