Over the past two decades China's rapidly growing economy is coupled with the consumption of large amounts of coat. An energy mix dominated by coal and inefficient energy utilization processes have led to increasingly serious problems of acid rain and sulfur dioxide pollution. Sulfur dioxide, carbon dioxide and particulate pollutions, resulted largely from coal combustion with little or no emission control, have become an environmental issue of widespread concern in China. So several years ago Chinese government began to reevaluate the advantages of natural gas and implement the Clean Energy Action Plan in some cities. In light of the study of the environmental benefit and from the project of natural gas replacing coal which was in Beijing, Yanan and Xian.Nanchong is regarded as one of three successfully typical cases of the national project of natural gas replacing coal , so it is representative in some senses.
