The world energy is less and less, but lives the exaltation of the level along with people now, science technique renewal speed quickly, the depletion of the energy is more and more big.Therefore, other can the development and exploitation of the renewable energy become all countries, is the urgent matter of the moment of the particularly flourishing nations.
Here introduce of making use of some general situations that the bagasse generate electricity at home and abroad, and its simple process and related equipments, and make use of the foreground and the summary that the bagasse generate electricity.
Bagasse is the largest by-product of the sugar production, it is sugar cane experiences squeezing or out juice residue remaining fiber processing, the bagasse yield is about 23-26% of the amount of sugar cane yield (about 60% water content of the bagasse), the amount of annual output of bagasse (as 50% moisture meter) around 200 million tonnes (1997), the quantity is quite big, and can be used as fuel combustion, save plant coal consumption, is a kind of abundant resources.

1. Cellulose: cellulose is a high molecular compound that is linked by many water-losing glucose groups. According to the determination, the cellulose polymerization degree in bagasse is about 3000, and the wood is about 1000.
2. Hemicellulose: bagasse is susceptible to dilute acid and dilute alkali, and is carbohydrates, which does not soluble in hot water, known as hemicellulose.
3. Lignin: it is a macromolecular compound, such as a hornet's honeycomb.
4. Other content: There is a certain amount of extraction in the bagasse, namely water extract and 1%NaOH extraction.
5. Benzyl alcohol, mainly cane wax, which is generally 2% ~ 4% of the quality of bagasse.
There are many formulate to calculate the heat value of bagasse, the most common one is Australia Hessey type:
Gross calorific value = (4636-- 12.3S-- 46.46W) *4.184kJ/kg.
Net calorific value = (4324-- 12.3S-- 49.04W) *4.184kJ/kg.
S - sugar (%),
W - water (%)
According to calculation
The gross calorific value of the bagasse is 9797.11kJ/kg,
The net calorific value is 8038.66kJ/kg,
The absolute dry bagasse calorific value is 19049.94kJ/kg ~ 19510.49kJ/kg.
