Abstract
A nozzle for atomization of liquid fuel by air flowing through the nozzle (20), with an air entry area (50), an air exit area (52) and a flow path (54) which connects the air entry area (50) to the air exit area (52), the nozzle (20) being made of ceramic material, an air guidance device (56) being provided in the air entry area (50) which imparts a swirl to the inflowing air, and the air guidance device (56) being an integral part of the nozzle (20). Furthermore, there is a heater (10) equipped with such a nozzle (20) for mobile applications.
Claims18
Nozzle for atomization of liquid fuel by means of air flowing through a nozzle (20) with
- an air entry area (50),
- an air exit area (52) and
- a flow path (54) which connects the air entry area (50) to the air exit area (52), characterized in that
- the nozzle (20) formed of ceramic material,
- that, in the air entry area (50), there are air guidance elements (56) which are adapted to impart a swirl to the inflowing air, and
- that the air guidance elements (56) are formed as an integral part of the nozzle (20).
Nozzle as claimed in 1, wherein the air guidance elements (56) are blades.
Nozzle as claimed in 1, wherein
- an at least essentially cylindrical part of the nozzle (20) has an essentially cylindrical shoulder (64) with an increased diameter and
- wherein the cylindrical shoulder (64) has recesses (66) for holding mounting pins (68).
Heater (10) for mobile applications, especially motor vehicles, with a burner (12) for combustion of a fuel/air mixture, the burner (12) having a nozzle comprising:
- an air entry area,
- an air exit area and
- a flow path which connects the air entry area to the air exit area, wherein
- the nozzle is formed of ceramic material,
- in the air entry area, there are air guidance elements which are adapted to impart a swirl to the inflowing air, and
- the air guidance elements are formed as an integral part of the nozzle.
