Among the renewable energy sources, biocnergy can by considered one of the possibilities being commercially viable. In many countries and organisations we can sec political will to expand the renewable and in some of them also was evaluated a legal barriers, created new regulations and incentive schemes. Biomass can be generated from forests, can be grown as bioenergy crops or obtained as a byproduct, wastes in different industrial and municipal processes. The key to successful biomass power development is To use mentioned above resources efficiently in modem conversion technologies that maximize the energy production and minimize investment and operating costs. In recent time we can see pressure to increase biomass generation from widen fuel base. Materials such short rotation crops ( willow, etc...) , industry residues, demolition wood, some of the agricultural and municipal wastes, have been added to the fuel mix. It causes new challenge due to their chemical composition and handling difficulties. However experience with recent, different FW projects ( boilers and gasifiers ) has shown that bioenergy can be developed not only in country rich in forests. Recycled biomass materials and agricultural products also can be used on a commercial scale. Now we have three ways for biomass thermal conversion : Direct-fired combustion: involves the oxidation of fuel with excess air, producing hot flue gases witch pro-duce steam in heat exchange sections of boilers (ot hot water). Co-firing : involves replacing a portion of the fossil fuel with biomass at an existing, high efficiency boiler. It is often the least-cost options. Gasification : it is major and the latest element in the development of improved "bio-power" systems. It is a process that converts solid, raw biomass material to a hot, low-calorific, flammable gasses. Among the different technologies the most proper one, for described above fuels is CFR - circulation fluid- ized bed technology. Since end 70's Foster Wheeler has been developing and implementing for industrial applications CHB boilers and gasification systems. Now it is over 370 boilers around the world. The newest solution of the fluidized bed technology is the CFB gasifiers. Its main advantage is that it allows converted biomass and different wastes to gaseous fuel that can be used in conventional boilers and others industrial furnaces in place of expensive fossil fuels. This technology was originally developed in response to fossil fuel prices to save operating costs and the environmental benefits that resulted from reducing waste volumes were seen as a secondary benefit. In the present time, when we arc able to increase wastes portion in biomass mixtures, that secondary benefit seems to be more and more important Gasifiers offer an efficient way to utilize biomass and recycled fuels. The direct gasification of the wet biomass and further co-combustion of this hot, row gases in the existing boilers offers many advantages such as : decreased SO2 and NOx emission, low investment and operation costs and utilization of existing power plant capacity. As the environmental awareness is growing and new legal regulations force use renewable energy sources for generation of electric and thermal power, the CFB gasification technology will meet the challenges of modern world. Foster Wheeler CFB technology is an effective, pcoven and reliable solution for industrial applications.
