文档介绍：摘要
城镇燃气化是城市现代化的重要标志之一。城镇燃气在发展生产、提高人民生活水平、节约能源、减轻污染、改善环境等方面起着重要作用。
本设计主要是针对合肥地区某市进行燃气管网的规划,该设计采用天然气为气源,燃气管道主要采用钢管。首先根据城市的面积及人口情况对该市的燃气需用量进行确定,然后根据用气量及规划要求进行管网设计。在设计燃气管网时,应全面考虑经济、技术等方面因素,选择经济合理的最佳方案。因此本设计选用了中压一级管网系统。
根据管网的布置和流量,经过水力计算的一系列步骤确定管径;再将管径作为已知条件,选取调压设施以及用户燃具以满足供应的压力要求,因此设计具有一定的技术性和经济性。

Abstract
Town gas is one of the important symbols of urban modernization. Town gas plays an important role in the development of production, improving living standards, energy conservation, reduce pollution, improve the environment.
The design is intended for a planning of city gas work in Hefei area, the design uses natural gas as the gas source, gas pipelines primarily used in the steel. Firstly, according to the city area and the demographic situation of the this area to determine the amount of gas needed; and secondly to design work according to the gas consumption and the requirements of the plan. In the design of gas work, the economic, technological and other factors should be prehensively; finally, we should choose the best economical solution. therefore this design has selected center presses level of works systems.
In the above work system, used the region to adjust the pressure to stand to the region air feed way. According to work arrangement and current capacity, process water putation a series of steps definite caliber; Again the caliber took the datum, after selects the accent to press the facility as well as the user again burns has satisfies the supply the pressure request. The design has the very good technical nature and the efficiency.
Keywords: Natural gas work Gas consumption Hydraulic calculation
