(267). Start a Bio Coal Making Unit
Bio coal is a solid form of bio energy, which has been gaining significant market in the foreign nations. However, it is still in the nascent stage in
due to limited supplies and inadequate marketing. With heating capacity ranging from 3500-4750 Kcal, bio coal will serve as a substitute to black coal. Since it is manufactured with biomass as its raw material and pressing as the process, it is known as biomass briquetting. India
Coal Briquetting is the process of converting agricultural waste into high density and energy concentrated fuel briquettes. Bio Coal Briquetting plant are of various sizes which converts agricultural waste into solid fuels.Briquettes are ready substitute of Coal/wood in industrial boiler and brick kiln for thermal application.
Bio Coal briquettes are Non conventional Source of energy, Renewable in nature, Eco friendly, non polluting and economical. Process of converting agricultural waste to solid fuel is also non polluting. It has not required to add any binder / chemicals so it is 100 % natural.
Every year millions of tons of agricultural waste are generated. These are either not used or burnt inefficiently in their loose form causing air pollution. Handling and transportation of these materials is difficult due to their low bulk density. These wastes can provide a renewable source of energy by converting into high-density fuel briquettes without addition of any binder.
Briquettes have high specific density (1200 Kg/m3) and bulk density (800 Kg/m3) compared to 60 to 180 Kg/m3 of loose biomass. These can withstand the stocks of long distance transport, Loading/unloading and transportation costs are much less, and storage requirement is drastically reduced. Compared to fire wood or loose biomass, briquettes give much higher boiler efficiency because of low moisture and higher density.Present in
Indian territory it has used in the Industries like Paper Mills, Solvent Extraction Plants, Vegetable Plant, Chemical Plant, Textile Units, Dying House, Food Processing Units, Milk Plant, Sugarcane Mills, Leather Industries, Laminating
Briquettes produced from briquetting of Bio Coal are fairly good substitute for coal, lignite, firewood and offer numerous advantages:
Bio Coal Briquettes are cheaper than coal.
Oil, coal or lignite, once used, cannot be replaced.
High sulfur content of oil and coal, when burnt, pollutes the environment.
There is no sulfur in Briquettes.
Bio Coal briquettes have a higher practical thermal value and much lower ash content
(2-10% as compared to 20-40% in coal).
There is no fly ash when burning Bio Coal Briquettes.
Bio Coal Briquettes have consistent quality, have high burning efficiency, and are ideally sized for complete combustion.
Combustion is more uniform compared to coal and boiler response to changes in steam requirements is faster due to higher quantity of volatile matter in Bio Coal Briquettes.
Easy to burn - lower ignition temperature compared to coal.
Smokeless burning and sustained combustion and the temperature requirement are achieved due to very efficient combustion.
No binder is used.
The natural polymer lignin acts as a binder and provides mechanical support and also provides resistance to decay and repels water.
Very well suited to gasifier which can run any engine because of the combustion efficiency and solid form.
In gasifiers the briquettes can be used and the partially pyrolysed briquettes can be again used as a substitute for high value added charcoal for domestic and industrial use leaving the fuel wood unutilized and thus avoiding deforestation.
A typical usage of briquettes made out of paper mill sludge mixed with iron sludge power is made in big furnaces to keep the temperature alive for easy start up.
Users of bio coal briquettes are eligible for carbon credits.
No pollution to the environment and no toxic gas and sulphur emission and even no odour.
Full heat value is utilized.
Easy to handle and 1000 kgs of briquettes per cubic meter can be stored and transported against 50 kgs of
Leaves only white ash without any fixed carbon.
