Bhaktinagar, Rajkot, Gujarat

We are manufacturer of biomass fuel briquettes (bio coal/white coal). We are having manufacturing facilities at different locations in Gujarat state.

Our briquettes are quality product having solid, firm formation with minimal cracks, minimum moisture and minimum impurities like sand, clay etc. It can give CV from 3800+ KCal/Kg. We currently manufacture 90mm briquettes with production capacity 3500 Tons per month. We mainly use groundnut shells and sawdust for briquetting.

Biomass briquette OR Biocoal is made from wastes such as sawdust, groundnut shells, cotton stalk, etc.; compresses it and then extrudes it to make a reconstituted log that can replace FO, Firewood and Coal. Burning a biomass briquette is far more efficient than burning firewood, FO or coal. Biocoal is cheaper than coal, wood and FO.

A number of companies in India have switched from furnace oil, fire-wood and coal to biomass briquettes to save costs on boiler fuels. The use of biomass briquettes is predominant in the southern parts of India, where coal and furnace oil are being replaced by biomass briquettes. A number of units in Gujarat and Maharashtra are also using biomass briquettes as boiler fuel. Use of biomass briquettes can earn Carbon Credits for reducing emissions in the atmosphere. Many large companies are supposedly using biomass briquettes for earning Carbon Credits by switching their boiler fuel. Biomass briquettes also provide more calorific value/kg and save around 30-40 percent of boiler fuel costs.

PRODUCT SPECIFICATIONS:

Size & shape of briquette = 90mm Dia. with 3" to 12" Length

Gross Calorific Value = 3800 to 4300 KCal/Kg

Moisture content = 5 to 8%

Ash content = 4 to 9%

Sulphur content = 0.5%

Volatile material = 55 to 65%

Fixed carbon = 17 to 22%

BENEFITS OF BRIQUETTES COMPARED TO COAL AND FIREWOOD

1 Briquettes are cheaper; CV per rupee spent is higher compared to coal or fire-wood.

2 This high density biomass fuel extends your burn times greatly

3 100% natural, no chemical, glue or binders used

4 Cost effective, huge saving compared to coal or fire-wood burning

5 Environmentally friendly using our renewable resources

6 Clean burning, minimal smoke, creosote and ash Briquettes do not emit smoke with sulfur or phosphorus and also fly ash, hence no need of pollution control equipment

7 Easy to handle and store

8 Low ash content (below 10%) in comparison to coal (25 to 40%) resulting least boiler ash disposal problems

9 Uniformity in size, density and moisture ensures predictable burning time

10 High sulfur content of oil and coal, when burnt, pollutes the environment. There is no sulfur in briquettes

11 Bio mass briquettes have a higher practical thermal value and much lower ash content (2 to10% compare to 20 to 40% in coal)

12 Briquettes have a consistent quality, have high burning efficiency are ideally sized for complete combustion

13 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 briquettes.

14 There will be no corrosion effect on boiler equipment resulting in negligible maintenance cost. Coal on the other hand produces Sulphur dioxide, which on mixing with moisture produces sulfuric acid and corrosive acid.
