The document discusses biomass power plants and using wood as an energy source. It addresses the strategic, environmental, social, and economic issues. Specifically, it discusses how using wood as an energy source can provide energy independence and stability. It also describes how biomass power reduces greenhouse gas emissions and pollution compared to fossil fuels. The document then discusses biomass cogeneration systems that produce both electricity and heat. It provides diagrams of biomass power plant systems including storage and grate designs.

3. WOOD AS AN ENERGY SOURCE
• Strategic issue;
• Environmental issue;
• Social issue;
• Economic issue.

4. Strategic issue
Using wood as an energy source represents a strategic
issue.
The use of wood as energy source contributes for energy
independence of the country.
A country energy availability and self-sufficiency
represents an economic stability factor towards global
fluctuations in the cost of fossil fuels.

5. Economic and Social Issue
The ability to generate primary energy at home and in their
own areas of consumption, represents the possibility of
injecting local investments to generate this energy, but
also save money or prevent the export of foreign currency.
Represents an additional option to generate wealth, to
move the economy and create jobs.
The electricity generated from diesel fuel, costs about 9
times more than the electricity generated from biomass
from waste wood from planted forests.

6. Environmental Protection
Using wood as an energy source to replace fossil fuels in
industry, limits the growth of greenhouse gases by
reducing emissions of carbon dioxide - CO2 - and removes
the pollution by sulfur, absent in the wood.
Energy recovery from waste wood industry, for example,
also avoids polluting by the burning of waste in the open,
and the acidification of groundwater or watercourses
caused by their improper deposition.

7. Biomass Cogeneration Systems
The cogeneration systems, that will produce both
electricity and useful heat, configure the most rational
technology for the use of fuels.
This is the case of the ethanol, pulp and paper industries,
which in addition of the electrical and thermal power
required, also have residual fuels that are integrated in a
favorable manner to the cogeneration process.
Cogeneration is used widely in the world, including
incentives from governments and from energy distribution
companies.

8. GRATE AND FUEL FEEDING
• Conical, rotating grate
• Fuel feeding with stoker screw
to the centre of the grate
• 3-5 rotating grate rings
• 2-4 fixed grate rings
• Ash grate

9. GRATE AND FUEL FEEDING
• Wide grate area for complete combustion
• Flexible, controlled primary air distribution
• Effective ash grate with air introduction
• Wet bottom ash system
• Grate material temperature measurement:
Flue gas recirculation used for grate cooling
