Combloc is packaged, multi-fuel fired steam boiler. The two major options for a solid fuel fired steam boiler were the Integrated Furnace Boiler and the conventional Hybrid Boiler. This meant that the choice boiled down to the reduced site work and better response to load of the Integrated Furnace Boiler, versus the promise of higher efficiency and fuel flexibility of the conventional Hybrid boiler so the ideal solution is the best of both of these designs packed into one which is Combloc. This robust product is a highly compact, efficient, plug and play packaged boiler.
Product Features
  • Compact, skid mounted and modular construction – up to 40% reduction in foot print
  • Pre-insulated and factory assembled – up to 80% reduction in site work
  • Flexibility of fuels (Biomass/ Fossil) and combustors
  • Quick startup and better response to load fluctuations
  • Multi-pass hybrid construction with high combustion volume – better efficiency
  • Easy ash removal and better accessibility for maintenance
Operating Range
  • Capacities: 1500 kg/hr to 10000 kg/hr (recheck capacity)
  • Firing Fuels: Wood Chips , Paddy Husk , Biomass Pellets ,Biomass briquette & Dry biomass
