Biomass fuels

Biomass fuels

Biomass fuel: refers to the combustion of biomass materials as fuel, generally mainly agricultural and forestry waste (such as straw, sawdust, bagasse, rice bran, etc.), mainly different from fossil fuels. In the current national policy and environmental standards, direct burning of biomass is a high-polluting fuel, only used in rural foci, is not allowed to use in the city. The application of biomass fuels is mainly Biomass Molding Fuel ("BMF"), which is used as a raw material, Shaped, granular, etc.), can be directly burned a new type of clean fuel.

origin

The diversity of geographical environment, so that different regions of the plant has its own special environmental adaptability, which provides a broad prospects for the supply of biomass fuels. Depending on the local climate and environment, plants that are ecologically and environmentally friendly, including perennial grasses, should be fully utilized to become a reserve for biomass fuels. The Institute of Energy and Biology is a collaborative research institute of the University of California at Berkeley, University of Illinois and Lawrence Berkeley National Laboratory. The bioenergy experts here have set up a special study on the supply of raw materials for lignocellulosic biofuels. The ecological environment and plant types around the world were analyzed to explore the sustainability of efficient biofuel production under existing conditions, with plants or crops that can not be eaten. Such as midwestern, eastern and northern drylands; Brazil and other tropical areas of sugar cane, which also in the southeastern United States; semi-arid areas such as Mexico, the southwestern United States agave and other sources of woody plants

Material fuel

If the use of additives, it should be agricultural and forestry products, and should indicate the type and number of use. The EU standard does not propose specific values for the calorific value of biomass fuels, but requires the seller to mark it. Swedish standards require that the calorific value of biomass fuels should generally be at 16.9 megajoules. In China's Henan, biomass fuel is one of the government's key support for the construction of new rural construction in 2008, there are currently Henan to open up machinery and prospecting machinery to introduce biomass fuel production technology and concepts, is China's first batch of machinery and equipment manufacturers

Such as the Midwest, the eastern and northern drylands of the mango; Brazil and other tropical areas of sugar cane, which is also in the southeastern United States; semi-arid areas such as Mexico, the southwestern United States agave and other sources of wood plant.

Characteristic advantage

1, biomass fuel heat, heat in the 3900 ~ 4800 kcal / kg or so, after the heat of carbonization up to 7000-8000 kcal / kg.

2, biomass fuel purity is high, does not contain other heat does not produce debris, its carbon content of 75-85%, ash 3-6%, water content of 1-3%, absolutely no coal gangue, stone and so on Heat but heat impurities, will directly reduce costs for the enterprise.

3, biomass fuels do not contain sulfur, do not corrode the boiler, can extend the life of the boiler, the enterprise will benefit.

4, because the biomass fuel does not contain sulfur phosphorus, combustion does not produce sulfur dioxide and phosphorus pentoxide, which will not lead to acid rain, do not pollute the atmosphere, do not pollute the environment.

5, biomass fuel clean, easy feeding, reduce the labor intensity of workers, greatly improving the labor environment, enterprises will reduce the cost of labor for the industry.

6, biomass fuel burned after the very little ash ballast, greatly reducing the stacking ballast site, reduce the cost of ballast.

7, biomass fuel burning after the ashes are high quality organic potash fertilizer, recyclable profitability.

8, biomass fuels are natural renewable energy, which is a vanguard in response to the central call to create a conservation-oriented society and an industry to nurture agriculture.
