提出浦东地区天然气转换的技术方案，从气源点起由近及远，分为６个５万户左右的小区，由高压至低压逐级转换，一年内完成．在输配管网转换中，根据现状近期采用不同级制过渡，可节省投资加快进程，最终再实现高中压二级输配系统．采用天然气直接置换人工煤气，当放散点取样煤气中ＣＯ≤１．０％时为合格． Proposed Pudong natural gas conversion technology program, from the gas source from the near and far, divided into six about 50,000 households in the district, from high pressure to low pressure step by step, completed within a year. In the transmission and distribution network conversion, according to the status quo in the recent adoption of different levels of transition, you can save investment to speed up the process, and finally to achieve high pressure secondary distribution system. Using natural gas directly replace artificial gas, when the release point of sampling gas CO ≤ 1.0% is qualified.
