How to Briquette the Bio-Mass
Almost any biomass can be briquetted. Briquetting plants set so far in India are using Saw Dust, Bamboo dust, Bagasse, Cotton Stalk, Coffee husk, Groundnut Shell, Mustard Husk/Stalk, Pine Needles, Rice Husk, Sugar Mill Waste, Jute waste, Coir pith and other wastes & residues like Castor Shell, Red Gram Stalk, Tobacco stem, Tea Waste, Sander Dust, Tree Bark, Wild Grasses & Shrubs i.e. Any type of Agricultural waste or forestry waste can be also briquetted individually or in combination without using any binder.
- Raw material like Saw Dust Is screened and stalk (Forest & Agro waste) are chopped by cutter chipper cum Grinder (Single Action) if the raw material size is larger than 25mm
- For using material of two or more types, It should be mixed in suitable form.
- If raw material has high moisture it should be reduced by Sun drying or using flash drier. Say if the moisture level is higher than 15% there would be a requirement of Dryer.
- Hammer mill grinder is used to grind the material to get desired grain size.
- Raw material (desired grain size) is transported by pneumatic system to holding bins fixed over Briquetting Press.
- By Screw conveyor, material is discharged from bin to the press.
- Material is compressed by ram through taper bored die. By compression temperature is raised & lignin come to the surface and binds the material by its natural binder.
- Briquettes are formed in shape of log and it is automatically pushed through cooling line to the storage point.
BENEFITS OF BIO-MASS BRIQUETTES:
Besides being cheaper alternative for conventional fuels, what makes its future brighter is easier availability of agro waste in ample quantity. With the rising awareness and demand for bio-mass briquettes, more and more industries across the sectors, are waking up to its benefits. More importantly, the various Governments too have realized its significance as cheaper and eco-friendly alternative to conventional source of fuels and energies. Governments are sparing no efforts to promote bio-mass briquettes by way of slew of tax benefits and financial incentives to boost the usage of bio-briquettes as alternate source of renewable energy. Let’s look at some distinguished benefits of bio-mass briquetting plants. The speedy viability of the project within a time frame of two years makes it more investment friendly.
- Rising demand due to rising cost of fossil fuel.
- Renewable source of fuel and energy
- Tax benefits and incentives
- Earlier viability
- Relaxed rules
- Pollution free because there is no sulfur content
- Easy mobility and transportation
- Contain high density
