Introduction
Today most of electrical or thermal energy is generated using non renewable energy sources. Their price is highly volatile and future availability of these resources is limited. Renewable energy sources on the other hand last long and provide energy Independence and security.
Short rotation crops provide most renewable means for power generation application where huge amount is combusted in few hours while it takes longer to grow them. Agricultural residues also are attractive sources of renewable energy. In the context of developing countries where the availability is high, their use as energy source for power generation contributes a lot to sustainable development.ยต
The use of fossil fuels for power generation further creates atmospheric air pollution. Renewable energy sources, on the other hand, provide clean sources of energy. In developing countries which use biomass heavily and create indoor air pollution everywhere, centralized power generation avoids air quality problems.
Biomass CFB units
CFB has wide applicability. It is especially useful for biomass based power generation. Also it is suitable for burning mixtures of various fuels which avoid seasonal fluctuations of biomass availability. CFB is highly adapted to fuel a property fluctuation which is common problem with biomass fuels. These in turn meets stable supply requirement of power generation. The figure below expresses how CFB deals with biomass problems when used for power generation.
