Fuel Capabilities

Different Fuels. Purpose-Built Power.

Select a fuel family below to inspect the matched combustion technology, technical solution, and operating reference.

Agricultural Residues (Bagasse, Husk, Paddy Straw)

Fibrous agricultural residues require balanced fuel distribution, controlled overfire air staging, and conservative furnace heat-release designs to prevent bed clinkering and low-temperature ash agglomeration.
