ISOTEX Ecotherm biomass fired thermic fluid heaters are engineered with advanced multi-fuel combustion systems capable of efficiently burning the full spectrum of agricultural, forestry, and industrial biomass waste fuels — converting low-cost waste streams into high-value process heat.
High-silica agro-waste from rice milling at ~3,200 kCal/kg; one of India’s most abundant and affordable biomass fuels — compatible with pinhole grate and bubbling bed combustion systems
Dried mustard crop residue from Rajasthan, MP, and UP; available in large volumes post-harvest at extremely low cost — ideal for stationary or dumping grate combustion
Cotton plant waste from Gujarat, Maharashtra, and Telangana; high-GCV agricultural residue widely available at negligible cost after the cotton harvest season
Fibrous residue from sugar mills at ~2,100–2,400 kCal/kg (dry basis); available in huge volumes near sugar belts — ideal for plants co-located with sugar industry
High-calorific agro-waste at ~4,200 kCal/kg from groundnut processing in Gujarat and Andhra Pradesh; excellent fuel quality with low ash content
Crop residue from wheat and paddy farming across Punjab, Haryana, and UP; abundant availability during post-harvest season — reduces stubble burning and converts waste to energy
Bamboo offcuts and processing waste from furniture and handicraft industries; high-energy-density renewable fuel with GCV of ~3,800–4,200 kCal/kg
Compressed agro-waste pellets (rice husk, mustard stalk, cotton stalk) at 3,800–4,500 kCal/kg; consistent calorific value, automated feeding, clean combustion — premium biomass fuel for bubbling bed systems
Densified biomass briquettes from agricultural and forestry waste; high-density, consistent GCV, and easier transport & storage vs loose biomass — widely available across India
Residue from edible oil expeller operations (groundnut cake, mustard cake, cottonseed cake); high-protein biomass with GCV ~3,500–4,000 kCal/kg — directly available from oil processing plants
Industrial paper waste from packaging plants, corrugated box manufacturers, and printing units; consistent calorific value waste stream for continuous biomass firing
Fibrous cotton and synthetic lint from textile spinning mills; combustible industrial waste available as a zero-cost or low-cost fuel source from own plant operations
The Ecotherm Multifuel Flexible Combustor is specifically engineered for biomass fuels — seamlessly adapting to variations in biomass fuel quality, moisture content, and bulk density to ensure uninterrupted operation with consistent thermal output:
Advanced fluidised bed technology for biomass pellets, mixed agro-waste, and high-moisture biomass — efficiency up to 82% on NCV basis with consistent combustion across variable biomass quality
Advanced combined technology for mixed biomass streams with variable particle size, moisture, and calorific value — maximum fuel flexibility for multi-source biomass procurement
Heavy-duty system for high-moisture, high-ash agricultural biomass including wet bagasse, green crop waste, and high-silica rice husk requiring extended residence time
Optimised for fine biomass particles including rice husk, paddy straw fines, and agro-dust — prevents grate blockage from fine-particle biomass fuels
Ideal for larger biomass fuels including briquettes, cotton stalk, mustard stalk, and crop residue bales with consistent burn time on a fixed bed
The Ecotherm delivers factory-assembled, plug-and-play biomass fired thermic fluid heating — eliminating traditional on-site erection costs and timelines while providing class-leading combustion flexibility, advanced automation, and long-term reliability for biomass HTF applications.
