INTRODUCTION
Biomass Fuel Utilization Prospect
Biomass energy, referring to plants or plant-derived materials which store solar energy in their inner part, is a renewable energy resource in the world. Biomass materials can be compressed into biomass pellets or biomass briquettes which are effective fuel for burning boilers or other heating use. It spreads in plants throughout the world which transfers continuously solar energy into chemical energy.
In fact, about 120 billion tons of biomass is formed each year by means of photosynthesis. But only 1% of the total energy capacity has been used as energy.It can supply about 14% of total energy consumption in the world. The energy capacity of biomass is five times of the total present energy consumption in the world.
Biomass Energy Present Situation
1. The reserves of oil, natural gas and coal are limited. These fossil sources will definitely be exhausted if people continuously exploiting them without limitation.
2. Nearly all countries are aware of the importance of environment protecting. Using fossil fuel has detrimental effect on the environment and ecology, especially the emission of CO2which threatens environment and climate more and more seriously.This impels people to value the development and utilization of renewable energy resources.
3. Agricultural production in developed countries is excessive.According to a report, the agricultural production of the EEC has exceeded the needs
of food industry.Recently, they raised the question of about 80 million hectare of land being changed to grow energy crops with long life.This biomass fuel would approach the total annual present consumption of fossil fuel in the EEC.
4. Developing countries are actively taking measures to promote their sustainable agriculture development, such as adopting multiple-level utilization technology of matter, realizing "no-waste production", improving resource using efficiency and reaching good circulation of agricultural ecology.
Development Trend of Biomass Energy
The development of society raises higher and higher requirements for energy.Low-grade fuel like coal is no longer suitable for the civilization. Biomass briquettes, which are made of kinds of plants and processed by biomass briquette machine, give high burning efficiency and have little pollution. Along with the development of modern science and technology, t It has become the development trend of biomass utilization that normal solid biomass fuel is converted to high-grade gas and liquid fuel and then further transferred to electricity and hydrogen energy, etc.
