Abstract

A flame producing assembly is disclosed which comprises a fuel container and a fuel nozzle arrangement. The fuel nozzle arrangement is configured to produce a flame and comprises a fuel supply channel and a fuel nozzle having a fuel nozzle opening. The fuel supply channel extends from the fuel container to the fuel nozzle opening of the fuel nozzle. The fuel nozzle opening is oriented along an axis A in a flame direction f. The wind resistant flame producing assembly further comprises a nozzle arrangement, a compressed fluid supply for storing compressed fluid, and a compressed fluid valve. The nozzle arrangement has a nozzle outlet which at least partially encircles the fuel nozzle arrangement and is suppliable with compressed fluid from the compressed fluid supply via activation of the compressed fluid valve.

First claim

1 . A flame producing assembly comprising:
a fuel container fillable with fuel, a fuel nozzle arrangement for producing a flame comprising a fuel nozzle and a fuel supply channel, the fuel supply channel extending from the fuel container to a fuel nozzle opening of the fuel nozzle, the fuel nozzle opening being oriented along an axis in a flame direction, wherein the flame producing assembly further comprises:
a nozzle arrangement having a nozzle outlet which at least partially encircles the fuel nozzle arrangement,
a compressed fluid supply for storing compressed fluid, and
a compressed fluid valve,
wherein the nozzle arrangement is suppliable with compressed fluid from the compressed fluid supply via activation of the compressed fluid valve, and wherein the nozzle arrangement is shaped such that, when being supplied with compressed fluid during operation of the flame producing assembly, an at least partially encircling fluid curtain is created around the flame.

2 . The flame producing assembly of claim 1 , wherein the nozzle arrangement is positioned around the axis and below the fuel nozzle opening in a direction opposite to the flame direction.

3 . The flame producing assembly of claim 1 , wherein the nozzle arrangement has one or more openings which together form the nozzle outlet.

4 . The flame producing assembly of claim 1 , wherein the nozzle outlet extends circumferentially at least partially around the fuel nozzle arrangement.

5 . The flame producing assembly of claim 1 , wherein the nozzle outlet is arranged radially distanced from the axis by a minimum predefined length to reduce or eliminate a disturbance of the flame by the fluid curtain.

6 . The flame producing assembly of claim 1 , wherein the nozzle arrangement is shaped such that an outlet direction of fluid flowing through the nozzle outlet is inclined outwardly with respect to the flame direction.

7 . The flame producing assembly of claim 1 , wherein the nozzle arrangement comprises an outer cylindrical wall and an inverted cone-shaped element which is arranged around the axis, distanced from the outer cylindrical wall in the flame direction such that the nozzle outlet is formed between the outer cylindrical wall and the inverted cone-shaped element.

8 . The flame producing assembly of claim 1 , further comprising a fuel valve and a fuel actuating mechanism for activating and deactivating the fuel valve, wherein the fuel nozzle is suppliable with fuel from the fuel container via activation of the fuel valve.

9 . The flame producing assembly of claim 1 , wherein the compressed fluid is compressed air,
wherein the compressed fluid supply comprises a compressed air container and a compressed air channel via which the compressed air container is coupled to the nozzle arrangement, the compressed air container being fillable with compressed air, and wherein the compressed fluid valve is a compressed air valve such that the encircling air curtain is created at least partially around the flame when the nozzle arrangement is supplied with compressed air during operation of the flame producing assembly.

10 . The flame producing assembly of claim 9 , wherein the compressed air container is refillable with compressed air.

11 . The flame producing assembly of claim 9 , comprising an air inlet valve coupled to the compressed air container, the air inlet valve being coupleable to an external air filling device to refill compressed air into the compressed air container.

12 . The flame producing assembly of claim 9 , comprising an embedded air filling device coupled to the compressed air container, wherein the embedded air filling device is adapted to press air into the compressed air container.

13 . The flame producing assembly of claim 12 , wherein the embedded air filling device comprises a deformable elastic pouch with a first valve coupled to the compressed air container to pump air into the compressed air container and a second valve coupled to an exterior of the flame producing assembly to draw in ambient air from the environment into the pouch.

14 . The flame producing assembly of claim 1 , wherein the fuel is used as compressed fluid,
wherein the compressed fluid supply is provided by the fuel container, the fuel supply channel and a fuel supply branch extending from the fuel supply channel to the nozzle arrangement such that the nozzle arrangement is coupled to the fuel container, wherein the compressed fluid valve is a compressed fuel valve being arranged in the fuel supply branch such that, when the nozzle arrangement is supplied with compressed fuel during operation of the flame producing assembly, ambient air is drawn into the fuel to create the encircling air-fuel curtain at least partially around the flame.

15 . An air curtain device for a flame producing assembly comprising: a nozzle arrangement being configured to create an air curtain at least partially around a flame produced by the flame producing assembly.

16 . The flame producing assembly of claim 8 , wherein the compressed fluid valve is operatively coupled to the fuel actuating mechanism such that the compressed fluid valve is activated and deactivated simultaneously with the fuel valve by the actuating mechanism.

17 . The flame producing assembly of claim 1 , further comprising an auxiliary actuating mechanism for activating and deactivating the compressed fluid valve separately of the fuel valve.

18 . The air curtain device of claim 15 , wherein the nozzle arrangement comprises:
a nozzle outlet which at least partially encircles a fuel nozzle arrangement of the flame producing assembly, a compressed fluid supply for storing compressed fluid, and a compressed fluid valve, wherein the nozzle arrangement is suppliable with compressed fluid from the compressed fluid supply via activation of the compressed fluid valve, and wherein the nozzle arrangement is shaped such that, when being supplied with compressed fluid during operation of the flame producing assembly, an at least partially encircling fluid curtain is created around the flame.

19 . An air curtain device for a flame producing assembly, the flame producing assembly being configured to produce a flame along an axis in a flame direction, the air curtain device comprising:
a main body having a central lumen along the axis therethrough for receiving a fuel nozzle of the flame producing assembly, wherein the main body is releasably mountable on the flame producing assembly such that the fuel nozzle of the flame producing assembly is received in the central lumen, an air nozzle arrangement provided in the main body and having a nozzle outlet which at least partially encircles the central lumen, a compressed air container for storing compressed air, the compressed air container being provided in the main body and being coupled to the air nozzle arrangement via a compressed air channel, and a compressed air valve for controlling supply of compressed air from the compressed air container to the nozzle arrangement, wherein the nozzle arrangement is shaped such that, when being mounted on the flame producing assembly and when being supplied with compressed air during operation of the flame producing assembly, an encircling air curtain is created around the flame.

20 . The air curtain device of claim 19 , wherein the main body is shaped such that the fuel nozzle of the flame producing assembly extends through the central lumen outside the central lumen in the flame direction.
