Cyclone boilers are another combustion technology suitable for biomass co-firing. Here the mineral matter in the fuel forms a slag that holds and captures the large particles, allowing the volatile and fine particles to burn in suspension providing intense radiant heat for slag layer combustion. The burners for cyclone boilers are generally large, water-cooled, and horizontal with the combustion temperature in the external furnace ranging between 1650 and 2000 °C. For optimum cyclone performance, the fuels are specified to meet certain requirements, such as ash content must be greater than 6% (too high for many pure biomass types), volatiles must be greater than 15%, and the moisture content must be less than 20% unless the fuel is dried . Cyclone boilers only need fuels to be crushed and not pulverized making them suitable for co-firing in that they require minimal modification for feeding and mixing the biomass and the coal .
