FR Range Biomass Boiler

Direct firing system with high-temperature fluidised bed combustion to maximise the energy yield of wood residues from wood processing

The very dry and dust-like fuel is blown through one or more feed pipes into the fully ceramic-lined, highly insulated combustion chamber. The blowing action combined with the specially-developed combustion chamber geometry ensures optimal burnout of the fuel and the required turbulence and flow characteristics.

The heat storage in the fireclay mass ensures correspondingly high efficiency combustion chamber temperatures, which guarantee low emissions. The horizontal three-pass flame tube/smoke tube boiler is mounted on top of the combustion chamber to serve as a hot water boiler up to 110 ºC or above 110 ºC. If required, steam boilers or thermal oil boilers can also be supplied.
