Research On The Application Of Natural Gas Distributed Energy

For a long time,the survival of mankind is mainly dependent on fossil energy.Fossil energy provides power for the development of human society and the world economy.With the improvement of people's living standard,more fossil energy will be consumed in the future.A large number of mining and use of fossil energy,causes air pollution,ecological environment destruction,thereby restricting economic development.In the face of great pressure on the environment,countries in the world have taken active measures to reduce the impact on the environment caused by fossil energy,not only the use of new technologies to improve energy efficiency,vigorously develop renewable energy,but also increase the proportion of clean energy consumption.At present,the consumption of fossil energy in primary energy in China is 86%,especially the proportion of coal consumption is relatively high,and the energy utilization efficiency is relatively low,which will have a great impact on the future economic development.In order to reduce the impact of fossil energy on the environment and ensure the sustainable development of social economy,China has accelerated the development and utilization of renewable energy in recent years.At the same time,the proportion of clean energy consumption is also increasing,the proportion of coal consumption is decreasing,and the energy structure is constantly optimized.At the same time,many effective measures have been taken in the promotion and application of energy saving and consumption reduction technology,among which distributed energy system is a widely used technology of energy saving and consumption reduction,and the comprehensive utilization efficiency of energy is relatively high.Natural gas heating and cooling supply system is the most widely used,saving the best distributed energy technology,it will be the cogeneration system of traditional and modern refrigeration technology are effectively combined,will fuel combustion high temperature flue gas generated by cascade utilization,first generation,re heating and cooling,reduce heat loss,natural gas heating and cooling supply system has the advantages of high energy utilization efficiency,high degree of automation system,set up a simple,small footprint,less pollutant emissions,is the effective way to achieve the goal of energy saving and emission reduction and sustainable development contribute to economic and social.Limited by natural gas exploration and mining technology,imperfect network system and high price of natural gas,the development of natural gas distributed energy system in China has basically been at a standstill in recent years.With the acceleration of natural gas resources development and the gradual increase of the coverage rate of natural gas pipeline network,relevant industrial policies have been promulgated.The distributed energy system has begun to develop in all parts of the country,showing an accelerating development in some economically developed areas.This paper mainly introduces the development situation of triple cold heating concept,distributed energy and natural gas distributed energy development,China's natural gas market supply of natural gas in recent years in the domestic market,and the principle for the cold gas heating system triple advantages and various system.This paper analyzes the construction and operation of a natural gas electrothermal cold triple supply project,and summarizes the existing problems in the development process of the electric heating and cooling system of natural gas.From a strategic perspective on the status quo and difficulties of natural gas distributed energy development,a comprehensive analysis of the environment for the development of natural gas distributed energy by SWOT analysis,reveals the development of China's natural gas distributed energy currently existing problems,proposed the development of natural gas distributed energy in China and suggestions.
