1.2MW Boiler Body

Ferroli Pressurised Steel Boiler

3 Flue gas pass with flame reversal in the combustion chamber.
– Heat exchanger designed for optimum ratio between the combustion volumes and the heat exchange surfaces
– Long life materials used in the construction
– Efficient turbulator improves heat exchange of the flue gas and lowers the pressure drop
– Tube bundle positioned above the combustion chamber ensuring flue gas is discharged into a hot environment preventing condensation forming
– Steel body lined with 80mm layer of glass wool, in turn covered by a layer of tearproof material
