Recently the national development and reform commission, the ministry of finance and the housing and rural construction and national energy board released "on the development of natural gas distributed energy guidance", puts forward the early in "1025" will start a batch of natural gas distributed energy demonstration projects, "1025" during construction around 1000 distributed energy project of natural gas, and the construction of all kinds of 10 or so typical features of distributed energy demonstration area.
The goal is to give opinions: 2015 years ago to complete natural gas distributed energy main equipment development. When the installed capacity to 5 million kw, solve the distributed energy system integration, equipment autonomization rate of 60%; When the installed capacity to 10 million kw, basic solution for gas turbines, micro and small and medium-sized core and independent production equipment, equipment autonomization rate reached 90%. By 2020, in the national scale above cities promote the use of distributed energy systems, the installed capacity to 50 million kw, preliminary distributed energy equipment industrialization.
Natural gas is distributed energy refers to the use of natural gas as fuel, through the cooling-heating-power supply, etc. To realize the energy of cascade utilization, comprehensive energy efficiency in more than 70%, and in load center came near to realize the energy supply modern energy supply mode. The system operation principle roughly as follows: natural gas into the combustion, the generator, provide electricity, gas to heat exchanger from the flue gas. Cold water and has come from internal combustion engine lubricants in oil in heat exchanger, in burning outdoor water wall heat exchanger heat, heat exchanger in flue gas in the flue gas and heat exchange, and produce hot water or steam, to give users; The hot water or steam into absorption refrigeration device (such as steam/hot water chiller of), the production of cold water as refrigerant, provide air conditioning service. In addition to small and medium-sized, miniature gas turbine, chiller, heat exchanger, the core equipment, the whole system integration is also a difficult point. Compared with the traditional way can centralized, distributed energy efficiency high with natural gas, clean environmental protection, safety, and cut the peak and valley, as well as good economic benefit.
China's natural gas distributed energy start later, mainly concentrated in Beijing, Shanghai, guangzhou and other big cities, installation site for hospitals, hotels, office buildings and the university, because technology, standard, interests, laws and regulations and so on aspects of the problem, mainly USES the "no grid" or "grid the Internet" way of operation. Guidance is expected to the release of a distributed in domestic energy that natural gas accelerated promotion.
Investment opportunity is concerned, is expected to the push of relevant policies, involving waste heat boiler, bromine cold machine generating heat utilization, small gas turbine, gas turbine relative auxiliary equipment distributed energy equipment and engaged in the contract of energy management related enterprise, will from large-scale distributed energy construction project of benefit fully, suggested to seek such concern investment opportunity.
