INCINERATION AND GASSIFICATION

FUELS:

BAGASSE, RICE HUSK

BAGASSE:

Calorific value: 2318 kcal/kg.

246gm per kilogram of sugarcane which is waste can be utilized to harness electricity.

Finds high potentiation sugarcane and ethanol industries.

Promotes co generation.

Ash which is waste of incineration process is used in brick factories and dehydrating

agents.

One of main pillars in co- generation.

2

RICE HUSK:

Calorific value: 4315 kcal/kg

Calorific value near to wood.

India is second largest in rice production.

Can be used for both gasification as well as incineration.

25%-30% paddy per unit kilogram paddy yields husk.

Presently used in brick industries and poultries.

10 mw plant needs 200 ton of rice husk per day.

Ash is used as insulator in solar cookers and used as dehydrating agent.

Silica fumes which are extracted from gasification is very costly bi product.

Can contribute in power grid if used effectively.

Preprocessing is not required but should be stored in dry place.

Transportation is bit difficult.

3

FERMENTATION:

Sugarcane juice, animal wastes and food wastes

Sugarcane juice:

One of widely used raw material in production of alcohol.

The extraction process is called molasses.

Fermentation process simple.

We have a great potential in sugarcane industry.

Ethanol is used for various purposes it is now substitute in IC engines, chemical lab uses,

medicine and many more.

Animal waste and food wastes:

Mainly used in biogas production.

Biogas can be used for cooking and can substitute LPG gas.

4

India has good potential in livestock rearing and this wastes can be used effectively

and can contribute to economic growth of country.

Any food wastes rich in glucose, starch, cellulose can be converted to biogas by simple

fermentation process.

Bio gas can drive diesel generators and can be used to harness electricity, but cost of

generation will be high.

Fermentation wastes are used as fertilizers.

PYROLYSIS:

Worn Tires, municipal wastes

TIRES:

Pyrolysis of waste tires can be used to produce a burning oil.

The burning oil is 25% more efficient than burning coal.

The environmental pollution will be reduced to one extent.

The best option next to recycling of tires.

The same technique can be used for plastics too.

It contains high amount of sulphur for desulphurification is must.

38%-50% of oil, 10%-20% of gas and 14%-56% 0f char.

5

MUNICIPAL WASTES:

Waste disposal is a challenging task for all countries.

One of solution for waste disposal is pyrolysis process.

Wastes are burned and converted to burning fuel which is use to harness electricity.

100tpd of municipal wastes can produce 2.5Mw of electricity.

Effective waste disposal, emissions are below regulatory values.

BIODIESEL

JATROPHA:

One of strong area of concentration bio energy R&D.

Effective fuel and efficient fuel for biodiesel synthesis.

Bio diesel is got from trans- esterification of oil.

6

Has a great future in reducing countries oil imports.

The present price of jatropha biodiesel is 26 rupees per liter.

It contains high oil and can easily be converted to biodiesel.

Can bring sustainable growth in agriculture and bio industries.

Economic fuel and can substitute present crude oil if its drawback are overcome.

It burns more cleanly than gasoline and diesel.

The yield of jatropha is 3000kg/hectare in India.

Other alternatives rapeseed oil, sunflower, palm which are costly as they are edible oils.

It is non edible and can only be used in bio diesel synthesis.
