Energy is the key factor in the Economic development and the requirement of the energy will increase and as the resources being limited there is all round search of alternatives resources of the energy and energy sources.
The product FUEL BRIQUETTES has a specialization of being pollution free property and high calorific value which is the need of time and in this critical period. Briquetted fuel as an ideal and ready substitute to Coal, Fire Wood, Charcoal, Lignite etc the fuel offers numerous advantages as mentioned below, other than consistent quality and economical prices :-
1. High calorific value ranging between 3000-5200 Kcal/kg depending on the material used.
2. Low fly ash contents of 2-10% as compared to 20-40% in Coal.
3. Non polluting as it does not emit any sulphur or phosphorus fumes and low fly ash.
4. As it produces from agro waste this is Eco friendly Fuel. Cheaper than coal as it utilizes waste and residues usually disposed off at no or low cost.
5. Loose material has a 100kg./m. cu. Of bulk density on the other Briquettes have a bulk density of 1000-1300kg./m. cu. And easy to handle or transport.
The concept of Briquetting is physical transformation of the loose material into acompactly compressed unit. The form change results in a much higher specific-density of the material which increases its combustion, efficiency as compared to the loose material. It also considerably reduces storage and transportation costs. The following agricultural and forest waste and saw mills waste and residues can easily be converted into Fuel Briquettes.
Which material can be used?
Agro Waste – Mustard waste, Groundnut shell, Sunflower & Maize stalks
Forest waste – Wood chips and shavings, Tree bark and twigs, Saw dust, Bamboo leaves, Wild grasses, Shrubs.
For a successful briquetting the raw material when feeder to the particle size must be less than 10mm and Moisture content of raw material must be 5% to 20%.
Manufacturing Procces
Raw material like as saw dust, Mustard Husk is screened and stalks (Forest & Agro waste) are grinded by Cutter Chipper after that grind by Grinder. For using material of two or more type, it should be mixed in suitable form. if material has high moisture it should be reduced by sun drying and Flash Drier. By Screw Conveyor, raw material is transported into pneumatic convey line in the presence of hot air. Dried material is collected by cyclone and the air lock system drop to holding bins fixed over briquetting press. Dust is collected by cyclone. By screw conveyor material is discharged from bin to the Briquetting Press. Material is compressed by ram through taper bore die by compression temperature rises and lignin come to the surface and binds the material by its natural binder. Briquettes are formed in the shape of logs and it is automatically pushed through cooling line to the storage point.
