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 densityBriquettes produced from briquetting of biomass are fairly good substitute for coal, lignite, firewood and offer numerous advantages.Briquettes are cheaper than coal Oil,coal or lignite once used cant 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 briquettesBriquettes 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 dont depend on erratic transport from long distances.The demand of fuel briquettes is increasing as the use of the briquettes is spreading and people becoming aware of its availability and advantages. Briquetted fuel can be used as a substitute of coal or firewood. At present it is being used in the following areas.1.Tyre Retrading units2.Tea processing units3.Boiler for raising steam in chemical, Textile processing industries4.Hotels and restaurants for raising steam5.Dryers and ovens for generation of hot air and many areas where firewood, Leco and coal used.Agro waste briquettes have certain benefits over coal likeEasy handling, packing and transportation of briquettes can be made in any conventional length and diameter.Low ash content( below 10%) in comparison to coal( 25 to 40%) resulting least boiler ash disposal problems.Regular supply of briquettes do not suffer from transportation bottle necks as the plant can be set up near raw material source and selling areas.There will be no corrosion effect on boiler equipments resulting in negligible maintenance cost. Coal on the other hand produces sulpher dioxide, which on mixing with moisture produces sulphuric acid an corrosive acid.Compare with coal even in terms of cal. Value per rupeeIt has low ignition point, when compared to leco and coalIt gives sustained combustion and more efficient combustion then loose agro wastesIt is a clean fuel.No gas and effluents like coal. So no health hazards.Easy handling compared to loose husk and fire wood.Low ash content. So less ash handling.Can be mixed with coal and fire wood of inferior quality which improves burning.Prevents environmental destruction due cutting off trees.
