Biomass Energy

Biomass Energy Points : biomass energy, definition of biomass energy, short note on biomass energy, biomass power plant Biomass is a natural substance formed in plants, equally in land and water. It contains crops, forest crops which are grow in energy farms, and animal dung. Fossil fuels obtain millions of years to type biomass (as an alternate fuel). It is indirect use of solar energy through the way of photosynthesis, as
Products of photosynthesis (or biomass) too identify as bio fuels, are large and include large amounts of water. Thus it is too expensive to move them over extended distances. Stored energy in them has to be utilizing in direct burning in regions close to source. Biomass can too be changed to a mixture of gaseous, liquid or solid fuels - every are biomass - consequent and thus call biofuels. Land crops can be of follow kind.
i) Forest crops, for example sweetgum, cultured hybrid poplar, alder and further hard woods.
iii) Sugar crop, for example sugarcane refuse or bagasse.
iii) Herbaceous crops, for example non woody plants.

Human and Animal waste are indirect land crop as of which ehtylene and methane can be formed as retaining fertilizer value of manure. An aquatic crop grows in fresh, sea and brackish waters contain seaweeds, mavine algae and different kelps.
There are three type of bioconversion method.
1. Direct combustion, for example wood waste and bagasse.
2. Biochemical conversion.
3. Thermochemical conversion.

Fermentation is break of difficult molecules in natural compounds by the help of ferment for example yeast, enzymes, bacteria and so on. Grains and sugar crops are changed through fermentation into ethanol. Ethanol with gasoline (called as gasohol) can use as an auto fuel.

Biochemical conversion too takes place with two ways that is anaerobic fermentation and digestion. Anaerobic diagestion is bacterial rotting of natural matter (biomass) in nonexistence of air or oxygen to eventually make a gaseous combination of methane and carbon dioxide in irregular volume ratio as 2 : 1. Carbon dioxide created by anaerobic digestion can removed to make synthetic natural gas, as the remain sludge retains it’s nitrogen to make a good fertilizer.

Thermochemical conversion takes place through two ways that is gasification and liquefaction. Gasification is prepared through heating the biomass by limited oxygen to make low heating value gas. The latter can be subjected to liquifaction through converting it into ethanol and methanol.
