1. UTILIZATION OF BIOMASS ENERGY
Electrical Energy Systems Lecture Notes Jane Namaganda-Kiyimba

2. BIOMASS ENERGY
Biomass is an organic matter produced by terrestrial and aquatic plants and their derivatives.
It is considered as a renewable energy source because plant life revives and adds to itself every year unlike coal , oil or natural gases.
Actually it is one , which harnesses the solar energy by photosynthesis.

3. CATEGORIES OF BIOMASS ENERGY
TRADITIONAL SOLID MASS
FUEL FORM
GASEOUS FORM
ETHANOL
METHONAL
WOOD AND
AGRI. RESIDUE
BIO GAS

4. STRIKING FUTURE OF BIOMASS
Ease of availability and cheap.
Renewal ability.
Possible decentralization of energy.
No storage requirements.

5. FACTORS INFLUENCING UTILIZATION OF BIOMASS
Factors pertaining to material , environment, economical & technical aspects will influence the utilization of biomass as a source of energy.
1) Material factors:
Biomass material contains moisture.
An increase in the moisture content decreases its calorific values.

6. 2) Economic & Technological factors
Bio material
Thermo chemical
conversion
Bio chemical
conversion
Combustion
Gasification
pyrolysis
Aerobic
Anaerobic

7. Ctd…
Cost of production could be the main concern in the commercialization of these process technologies.
In the case of biomass it has been estimated that the production cost is very close to that of conventional source energy production.

8. 4)Environmental factors:
Public attitude and the environmental impact at global and local levels influence the use of biomass.
Depending upon the fuel use, NOX emission ranges from low to moderate.

9. CONVERSION OF BIOMASS INTO SUITABLE ENERGY CARRIERS
The loose biomass available is affected by
moisture content , lower density and ash content.
These result in lower calorific value and less efficiency.
It is preferred to convert loose biomass into energy packed in the form of solids, gases and liquids.

10. ADVANTAGES Cheap and clean
No formation of hazardous gases i.e CO2 and CO due to complete combustion
Saving of conventional fossils like Liquefied Petroleum Gas (LPG), Kerosene
Lower cost of production
