Advantages And Disadvantages Of Biomass

888 Words4 Pages
Biomass gasification means incomplete combustion of biomass resulting in production of combustible gases consisting of Carbon monoxide (CO), Hydrogen (H2) and traces of Methane (CH4).
 Advantages of gasification are,
- Can be used for thermal application and electricity generation.
- Low cost of power production and low initial investment.
- It is highly efficient process.
- Gasification has thermo chemical conversion efficiency in the range of 70 % to 90% which is highest among different alternatives.
- The area requirement for gasification equipment is the lowest per unit output of energy in the form of heat and/or electricity.
- Gasification output capacity, especially in the high output ranges, is controlled only by availability of adequate feed materials rather than other technical consideration.
- Gasification offers high flexibility in terms of various biomass materials as the feedstock.
Gasification is a thermo-chemical process by which carbonaceous (hydrocarbon) materials (coal, petroleum coke, biomass, etc.) can be converted to a synthesis gas (Syngas) or producer gas by means of partial oxidation with air, oxygen, and steam. The device which performs this work is known as “gasifier”. Gasifier is a chemical reactor where various complex chemical and physical processes take place. The gasifiers main function is to pyrolyze the biomass and produce VM, producer gas and carbon and convert volatile matter into permanent gases in
