What is Bio Mass Briquettes?
Every year millions of tons of agricultural wastes and forest residues are generated. These are either wasted or burnt inefficiently in their loose form causing air pollution. Handing and transportation of these materials is difficult due to their low bulk density. These wastes can provide renewable source of energy by converting in to high density fuel briquettes with out addition of any binder
Briquettes have high specific density (1200kg/m3) and bulk density( 800kg/m3) compared to 60 to 180 kg/m3 of loose bio mass. These can stand the ardors of long distance transport. Loading/ unloading and transportation cost are much less and storage requirements is drastically reduced. Compared to firewood or loose bio- mass, briquettes give much higher boiler efficiency because of low moisture and density
Why Bio Mass Briquettes?
- Briquettes are cheaper than coal.
- Oil,coal or lignite once used can´t be replaced
- High sulfur content of oil and coal, when burnt, pollutes the environment. There is no sulfur in briquettes.
- Bio mass briquettes have a higher practical thermal value and much lower ash content(2-10% compare to 20-40% in coal).
- There is no fly ash in burning briquettes
- Briquettes have a consistent quality, have high burning efficiency 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 briquettes.
- Briquettes are clean to handle and can be packed in bags for ease of handling and storage.
- Briquettes are usually produced near the consumption centers and supplies don´t depend on erratic transport from long distances.
Benefits of using Bio Mass Briquette:
- The use of biomass briquettes or White coal as it is popularly called is easy to handle, store and transport.
- Environmentally, the use of Bio-mass briquettes produces much fewer greenhouse gases, specifically, 13.8% to 41.7% CO2 and NOX. (source Wikipedia)
- They result in much lower Sulphur Dioxide emission compared to fossil fuels like coal
- Briquettes contains low moisture (5 to 7%) compare to coal (20 to 25%)
- They are fairly resistant to water degradation, a problem encountered while burning wet coal.
- They have much lower ash content of 3 to 7 % compared to 20% found in coal.
- There is no generation of fly ash while burning
- Industries using Bio-mass briquettes can claim carbon credits
- While burning loose Bio-mass has lower thermal efficiency and higher air pollution, these problems can be overcome by using Bio Mass Briquettes.
