Boiler Fuel: Wood Chips, Pellets & RDF
Biomass Boiler Fuel
A boiler is designed around its fuel, and in the biomass and waste-to-energy world that fuel is not one product but a spectrum. Wood chips, pellets and refuse-derived fuel each burn differently, with different moisture, density and handling, and the choice shapes the boiler’s feed system, grate and controls from the start.
The Main Fuel Options
- Wood chips and bark, cheap and abundant but variable in moisture and size.
- Wood pellets, dense, dry and uniform, easier to handle and burn but more costly.
- Refuse-derived fuel, the prepared non-recyclable fraction of waste, energy-rich but demanding on emissions control.
Why Fuel Leads the Design
A boiler that burns uniform pellets can use a simple, efficient feed, while one burning wet chips or refuse-derived fuel needs bigger storage, drying and a combustion system that tolerates variability. Matching the boiler to the actual, affordable fuel supply is what determines both the capital cost and the long-term fuel economics of the plant.

Match the Boiler to the Fuel You Have
Klean Industries sizes biomass and waste boilers to the fuel supply actually available, so the plant burns what it has efficiently.
