Abstract
One seventh of total energy consumption is from biomass which is the main energy resource for over 1.5 billion people in the world. Biomass energy is the only one which has both the property of fossil fuel and characteristics which mean that it can be stored, renewed and transferred. It is less restricted by natural conditions. Biomass energy can be transferred to useful thermal energy, electrical energy and the fuel as power by means of direct combustion, gasification and liquidation. High-grade combustible gas like CO, H2 and methane can be formed by the gasification of biomass. Biogas can be produced by anaerobic digestion of biomass and liquid fuel using, for example, thermalization, biochemistry, machinery and chemistry.
Key Words: biomass energy, energy, value, development and utilization
I. Introduction
Energy is the material basis on which human beings rely and carry out economic development. Its reasonable development and efficient utilization relates to the future of the world. Renewable biomass energy occupies an important position and plays a decisive role in the present world energy structure. According to statistics, one seventh of the total world energy consumption is from biomass. In developing countries, the proportion of biomass in total energy consumption is even more. At present, about 1.5 billion of the world population has biomass as its main energy resource. So, how to use biomass energy, a kind of potential renewable energy resource, more efficiently and make it play an important role in the coming century. This is an issue which is being paid more and more attention.
