Abstract
A method for converting a gas boiler into a liquid-fuel boiler. The gas boiler comprises an enclosure which accommodates a firebox, which forms a combustion chamber and is provided with a supporting wall which supports a burner provided with a combustion head, which protrudes from the supporting wall and has a substantially cylindrical shape with an internal cavity formed axially; the enclosure is provided with a passage in which an atomizing nozzle, connected to a liquid fuel supply duct, and at least one ignition electrode are inserted from the outside; a snorkel-shaped body is also applied to the end of the combustion head that is opposite with respect to the supporting wall and the supply duct is connected supply duct is connected to a pressurized source of liquid fuel.

A method for converting a gas boiler into a liquid-fuel boiler, said gas boiler comprising an enclosure which accommodates a firebox, which forms a combustion chamber and is provided with a supporting wall which supports a burner provided with a combustion head, which protrudes from said supporting wall and has a substantially cylindrical shape with an internal cavity formed axially, which is open at the free end of said combustion head that is directed opposite with respect to said supporting wall and is provided, on its internal surface, with a plurality of dispensing openings connected to a supply duct which is fed with a mixture of air and gas in order to generate a flame in said internal cavity, wherein said enclosure is provided with a passage that is substantially aligned with an axis of said combustion head and is adapted to connect an outside to the internal cavity of said combustion head;
- a nozzle for atomizing liquid fuel, connected to a duct for supplying liquid fuel, and at least one ignition electrode connected to an electric power supply cable, are inserted from the outside through said passage;
- a snorkel-shaped body is applied to an end of said combustion head that is opposite with respect to said supporting wall;
- said supply duct is connected to a pressurized source of liquid fuel.
A gas boiler comprising an enclosure, which accommodates a firebox forming a combustion chamber, and provided with a supporting wall for a burner provided with a combustion head, which has a substantially cylindrical and internally hollow shape, is connected to a duct for feeding a mixture of air and gas and has, on an internal surface thereof, a plurality of dispensing openings in order to generate a flame inside it, wherein it has, in said supporting wall, a passage that is substantially aligned with an axis of said combustion head for the insertion of an atomizing nozzle which is connected to a duct for the supply of liquid fuel and with an ignition electrode which is connected to an electric power supply cable.
A liquid fuel burner, comprising a combustion head which has a substantially cylindrical shape with an internal cavity formed axially and is open at a first end of said combustion head and has, on an internal surface thereof, a plurality of dispensing openings connected to an air supply duct, in said internal cavity there being an atomizing nozzle, connected to a duct for the supply of liquid fuel, and an ignition electrode, connected to an electric power supply cable, a snorkel-shaped body being provided at said first end of said combustion head.
