“DUPLO” ASNG/2 is the only burner that can be operated with either heavy oil or gas. It boasts the same features as the conventional ASN/7 gasifier, that is to say:

strictly volumetric control of the amount of fuel oil
automatic adjustment by Inverter
device for automatic purging of the fuel oil supply pipes (every time the electric power supply fails. This prevents coking and therefore blockage of the diffusers)
the switch from fuel oil combustion to gas combustion and vice versa is reduced to two simple steps:

switch from fuel oil to methane gas or vice versa on the electrical panel
move the individual flexible hoses from the fuel oil duct (N) to the gas duct (G) or vice versa
The air pressure will need adjusting after these operations have been performed as gas combustion requires a lower air pressure than fuel oil combustion.

Use of the “DUPLO” burner easily resolves various issues:

any interruption in the supply of gas from the gas company, which can often occur without warning
the need to use mixed firing to overcome problems inherent to clay (efflorescence and staining)
the opportunity to choose the fuel based on the calorific value, which can vary

Use of the “DUPLO” burner can easily resolve various issues:

any interruption in the gas supply from the gas company, which can often occur without warning
the need to use mixed firing to overcome problems inherent to clay (efflorescence, staining, etc)
the opportunity to choose to use one fuel or the other based on the market cost; this opportunity will offer energy savings.
