Thermal Efficiency
Engineered with advanced automated combustion systems specifically optimised for compressed biomass pellets, delivering consistent calorific value, reliable auto-feeding, lower ash generation, and superior thermal efficiency compared to raw biomass fuels.
Premium EN-Plus / ISO 17225 grade compressed wood pellets; highest calorific value, lowest ash, and cleanest combustion for maximum boiler efficiency
Pellets manufactured from rice husk, mustard stalk, cotton stalk, sugarcane bagasse, and other agro-residues; widely available and cost-effective across Indian agro-industrial belts
EVOLUTION boiler can be fitted with a fully automatic pellet burner, allowing industries to shift to clean biomass fuel.
Pellet Burner Advantages:
Stable flame & high thermal efficiency
Cloud remote monitoring
Biomass pellets are carbon-neutral under UNFCCC standards; combustion releases only the CO₂ absorbed during plant growth
Pellet combustion produces significantly lower SO₂, NOx, and particulate emissions compared to coal or heavy oil
Compressed pellet form delivers consistent GCV (3,800–4,800 kCal/kg) with low moisture (≤10%), maximising combustion efficiency
Wood and agro-pellets manufactured from certified renewable or waste biomass sources support circular economy goals
Supports scope 1 emission reduction targets; SMARTWIZ generates verifiable carbon savings data for annual ESG reporting
