摘要:

随着我国天然气管网的互联互通,研究具有不同燃烧特性的天然气的互换性具有重要的现实意义。针对香港某电厂的气源多元化,进行天然气热值调整工艺研究,采用添加LPG来升高热值、添加氮气(或者液氮)、空气等低热气体来降低热值的方法具有可行性。 

Abstract:

With the interconnection of natural gas networks in China, there is an important practical significance to research natural gas interchangeability with different combustion characteristics. Based on the gas source diversification of some power plant in Hong Kong, this paper studies the technology of natural gas heat value adjustment. It is proved that the method of adding LPG to increase the heat value, and adding nitrogen (or liquid nitrogen), air or other low calorific gas to reduce the heat value is feasible.
