Present situation of bioenergy utilization in China

Biomass

Biomass refers to various organisms through the production of the atmosphere, water, land and other photosynthesis, that is, all living organic matter that can grow is known as biomass. It includes plants, animals and microorganisms.

Generalized concept: Biomass includes all plants, microorganisms, and animals that feed on plants and microorganisms, as well as the wastes they produced. Representative biomass such as crops, crop waste, timber, timber waste, and animal waste.

Narrow sense concept: biomass mainly refers to the lignocellulose such as straw, trees and other wood cellulose in the process of agriculture and forestry, in addition to grain, fruit and so on, agricultural products processing industry waste, agricultural and forestry wastes and livestock manure and wastes in the production of animal husbandry.

Features: renewable, low pollution. wide distribution.

Present situation of bioenergy utilization in China

China has developed a variety of fixed bed and fluidized bed gasifier, which use straw, sawdust, rice husk and branches as raw materials to produce gas. In 2006, more than 800 units were used for drying wood and agricultural and sideline products, rural straw gasification centralized gas supply system is close to 600, annual production of 20 million cubic meters of biomass gas.

The Chinese government and relevant departments also attach great importance to the utilization of biomass energy, the research and application of biomass energy utilization technology has been ranked as a key scientific and technological project in four five-year plans. The research and development of biomass energy utilization technology are carried out, such as household biogas digesters, firewood, firewood Kang, large and medium-sized biogas project, biomass briquetting, gasification and gasification power generation, biomass liquid fuels, a number of outstanding achievements have been made. As to policy, the renewable energy law was adopted at the fourteenth meeting of the Standing Committee of the Tenth National People's Congress on February 28, 2005, it has been officially implemented since January 1, 2006, and in 2006, the corresponding measures have been introduced. This shows that the Chinese government has legally defined the status of renewable energy, including biomass energy in modern energy, and the policy has given a huge preferential support, therefore, China's biomass energy development prospects and investment prospects are very broad.

• At present, the market is still in the period of development, and the technology and market are not perfect enough
• Civil relatively more, but the concept of serious speculation, the market is relatively confusing
• Industrial market development is relatively slow, a lot of technology is not mature enough, cut into the enterprise is not much;
• As the development environment becomes better, the biomass energy industry will develop rapidly in recent years

The development of biomass fuel, biomass energy boiler and biomass combustion machine has been successfully developed

The development of biomass fuel, boilers and combustion engines can completely replace wood, coal, oil and gas, are high efficiency, environmental protection, energy saving and renewable products, it is also a new energy revolution. Recently, experts in various fields in China have highly appraised the new product developed by a boiler factory in Liaoning Province, which is jointly developed by relevant institutions and research institutes. The technical principle of the boiler plant is to add two kinds of mineral raw materials in the process of straw granulation, without affecting the burning value, make sure that the particles are solid as hard as wood. At the same time, their biomass fuel and biomass boiler design novel and unique, give full play to the burning value of fuel. Many times monitoring by Liaoning environmental monitoring center, the combustion effect of the new boiler reaches the national standard of protection zone, each index is superior to the national standard, in particular, the emission of nitrides and sulfides is near zero. Its combustion cost is equal to that of common coal, which is 1/3 of oil, 1/2 of gas and 1/5 of electricity.
