Biomass heating has the characteristics of green low carbon environmental protection, is an effective way to control county coal pollution, is also developed countries general promotion measures.Although promising, in the initial stage of the biomass heating system still faces policy, standards, industry, etc.The county clean implementation of biomass cogeneration heating notice of the construction of the demonstration project of release will be a living material heating units, further biomass heating is expected to become a "powerhouse" clean heating.
Recently, the national energy administration, issued the implementation of county clean biomass cogeneration heating notice of the construction of the demonstration project, the organization to declare requirements on September 15 county clean biomass cogeneration heating demonstration projects, and to demonstrate the new project priority for approval, care demonstration project and clean around the heating support policy, after the completion of priority access to the national renewable energy subsidies. Experts say that, taken together, biomass heating is expected to be a "new force" for clean heating, with huge market potential.
Winter in the northern region, the clean and warm, warm winter relations to the north and the masses, relationship between haze days can reduce, energy revolution, the production and consumption is the important content of rural lifestyle revolution. But the level of economic development, residents intensity distribution, regional power load factors, such as parts of the city, urban and rural joints, such as rural areas surrounding the cannot realize central heating, also use large amounts of dispersed small coal-fired boilers, small furnace, such as heating, the heating way often use cheap but high sulfur content of coal, heating effect is poor, and the huge air pollutant emissions.
Biomass heating has the characteristics of green and low carbon and environmental protection. It is an effective way to control coal pollution in county area, and is widely promoted in developed countries. European association 2016 annual statistical report released by the biomass for electricity and heat energy of the share of renewable energy in a short span of 10 years has increased nearly 1 times, in part because of the strong expansion of biological energy, is widely used in cogeneration power plant, urban central heating plant and modern household furnace.
It is understood that the biomass heating of our country is mainly based on biomass formed fuel boiler, which is used to generate heat directly from the forming fuel. Since 2014, the national energy administration has adopted a pilot and demonstration method to actively promote the largescale and industrialized development of biomass forming fuels. On the basis of the pilot project in 2015, the construction of a demonstration project for the heating of biomass forming fuel boiler was organized. At present, China has formed 100 county-level towns with biomass energy heating, and the annual consumption of biomass is about 8 million tons.
"As the environmental pressure increases, the demand for clean energy is unstoppable and biomass heating is in good condition." Energy research institute, the national development and reform commission, said zhou, director of biomass shaped fuel heating technology in our country and basic mature operation model, special molding fuel boiler equipment manufacturing have scale, such as forming a group of powerful leading enterprises, pollutant emission control is also quite good, has the potential of alternative coal for heating.
For the prospect of biomass heating, first, the biomass energy resources of China are very rich, and the current usage is less than 10%. Secondly, China's heating market is large enough; In addition, the simple heating is turning to the heat and electricity generation, especially the heating of the industrial park has already shown the way of multiplex production, the energy utilization efficiency is higher, the economy will be better.
Although the foreground is optimistic, in the initial stage biomass energy heating still faces the policy, the standard, the industrial system and other aspects of the problem. First, there are some local documents and regulations that are not conducive to the application of biomass forming fuel. Beijing, nanning, shenzhen, foshan and other places have issued documents to ban or restrict the application of biomass forming fuels, and there are also many other places to oppose and resist. 2 it is lack of straw briquette fuel boiler with its own clean environmental protection features that meet the needs of special air pollutants emission standards, some local mistakenly think that straw briquette fuel like coal boiler, boiler and limit its development; Third, the industrial system is not perfect. Lack of complete specialized raw material collection, transportation, storage and supply system, the storage and transportation efficiency is low, it is difficult to meet the need of largescale utilization; Fourth, the subsidy policy is not perfect. The subsidy support for biomass forming fuel should be transferred from the supporting front-end molding fuel production to the clean combustion of the terminal boiler.
The national energy administration is pushing for a demonstration project to further explore new sources of biomass heating. For the next step development, in charge of the national energy administration said that one is the development of biomass energy as an important measures against atmospheric pollution, environmental protection strategy, a clear positioning and the role in protecting ecological environment; Second, establish and improve the industrial system, study the establishment of specialized raw material collection system and operation mechanism, introduce the pollutant emission standard of biomass boilers, and carry out the standard system construction; Third, we will improve the policy support system, incorporate biomass energy into the energy industry, establish a priority utilization mechanism and an efficient management system, and introduce a policy of terminal subsidies and preferential taxation policies.
