Study On Energy Efficiency Assessment Of Natural Gas Distributed Energy

Natural gas distributed energy projects has been makeing a more rapid development as an important plate of natural gas power generation,nowadays in China?Based on the theory of life cycle assessment and the method of environmental benefit assessment,this paper studies the environmental benefit assessment of natural gas distributed energy,aims to analyze the environmental benefits of natural gas distributed energy in common power generation mode,and provide guidance for energy saving and emission reduction in power industry.In this situation,the study of the comprehensive value of natural energy distribution of environmental impact,the establishment of appropriate environmental value assessment model,is conducive to effectively promote the scale of China's natural gas energy distribution applications to promote domestic low-carbon,clean energy development.Through the gradual establishment and improvement of relevant aspects of research for China's natural gas distribution of energy to lay a solid foundation for further development.This paper studies the environmental cost and environmental benefits of natural gas distributed energy from the perspective of LCA,and applies the theory of life cycle assessment to the environmental benefit assessment of natural gas distributed energy.First,the status quo of research on the distributed energy and environmental benefits of natural gas at home and abroad is described;Secondly,it summarizes the theory of natural gas distributed energy,environmental benefit evaluation and life cycle evaluation,and defines the life cycle of natural gas distributed energy according to the theory of life cycle evaluation.It mainly defines the three life cycle stages(fuel acquisition,Transport and triple production).After that,the calculation model of environmental efficiency is established and the calculation formula of environmental benefits is given.On this basis,through the empirical study,the natural energy distributed energy project is obtained.Environmental cost and alternative environmental value of thermal power generation,it proves that it has relatively significant environmental benefits in the commonly used power generation mode and determines the core link of natural energy distribution energy and environmental benefits.Finally,it puts forward effective countermeasures and suggestions for the development of natural gas distributed energy...
