Biomass Energy
Energy sources are not only the material basis that people live by, but also the fundamental conditions of national economic development. As a large energy consumption nation, China mainly depends on fossil energy like coal, petroleum, and natural gas for its energy supply. However, the limitation of fossil energy and its pressure on the environment has resulted in its exploitation severely restricting the sustainable development of the economic society.
Diesel oil and natural gas belong to nonrenewable resources. They can not control the increase of carbon dioxide. However biomass includes many types of organisms formed in photosynthesis. Biomass energy is a kind of solar energy stored in biomass in the form of chemical energy. It bases on biomass, and comes directly or indirectly from the photosynthesis of green plants, so it is renewable and sustainable. In living plants, biomass absorbs carbon dioxide; when burning, it releases carbon dioxide. As a result, it increases no amount of carbon dioxide into the atmosphere. Biomass pellet fuel is produced by mechanical compressing herbaceous or ligneous plants, with or without addictives, to form regular shaped fuel products. Being clean and environmentally friendly, biomass pellet fuel is an excellent replacement of diesel oil, natural gas, and/or coal.
It has become an earnest concern all over the world to explore new energy sources as the replacement of fossil fuels because of energy shortages, and environment pollutions like global warming which is caused by fossil energy consumption. The pressure to sustain development is becoming more and more severe is also a concern.
