Multi-fuel retrofitting and hybrid burner systems enabling fuel flexibility and decarbonisation of existing assets.
As India’s industrial sector transitions away from fossil fuels, ISOTEX offers a practical, proven path: hybrid and fuel conversion solutions that allow existing boilers to operate on alternative or multiple fuels — without replacing the asset.
Transition your fuel — keep your asset. ISOTEX engineers fuel conversions that protect existing capital investments while opening the path to net-zero.
Grate and combustion chamber modifications enabling existing coal boilers to fire biomass fuels — agro-residue, wood chips, pellets — with full steam output retention.
Combustion system replacement for oil/gas fired boilers to operate on solid biomass fuels. Full IBR re-certification included.
Hybrid burner and fuel feeding systems allowing simultaneous or switchable operation on multiple fuels for supply security and cost optimization.
Conversion of conventional stoker/grate fired boilers to Fluidized Bed Combustion for superior fuel flexibility and lower emissions.
Fuel handling, storage, and feeding system upgrades for pellet and briquette-grade solid biomass fuels.
Dual-fuel burner installation on existing oil/gas boilers enabling LPG/NG/FO switching for fuel price and availability optimization.

Reduced Fuel Cost
Biomass fuels typically cost 40–60% less than equivalent fossil fuel energy — significant savings at scale.
Carbon Footprint Reduction
Switching to certified biomass can reduce Scope 1 emissions by 60–90%, supporting ESG and sustainability mandates.
Rapid Payback
Most fuel conversion projects achieve full payback within 12–24 months from fuel cost savings alone.
No New Boiler CAPEX
Conversion of existing assets eliminates the capital cost of new equipment while achieving fuel transition goals.
