Full Text	This invention relates to a fuel economising flame heating apparatus for heating an object. Flame heating apparatus has many forms, one example of which is the domestic stove. To take the case of the domestic stove, fuelled by gas or a liquid fuel, such as, kerosene, it is common experience that while heating an object, such as, a vessel containing a food substance, a part of the flame of the stove goes beyond the side of the vessel without remaining in contact with the vessel. To this extent, there is waste of fuel. This invention therefore proposes a flame heating apparatus which does not allow any part of the flame to be rendered useless, by not remaining in contact with the vessel. Consequently the proposed apparatus saves fuel. Other beneficial aspects of this invention will be apparent from the description appearing hereunder. The fuel economising flame heating apparatus for heating an object, according to this invention, comprises a source of fuel; means connected to the said source for generating a flame for heating the object, characterized in that a guide vane assembly is provided around the flame; and a pump for sucking atmospheric air and directing such air against the flame for causing the flame to contact the object with respect to a specific surface area thereof to be heated. This invention will now be described with reference to the accompanying drawings which illustrate, by way of example, and not of limitation, one of possible embodiments of the flame heating apparatus proposed herein, wherein Fig. 1 illustrates a sectional view of a specimen of the known gas stove Fig.2 illustrates a sectional view of the embodiment Fig. 3 illustrates a separate view of the embodiment alone Fig.4 illustrates a view of the embodiment with one kind of flame formation And Fig. 5 illustrates a view of the embodiment with another kind of flame formation (Mat formation) The fuel economising flame heating apparatus for heating an object, is exemplified in the drawings as a gas stove K having a fuel tank F as a source of fuel.

This invention relates to a fuel economising flame heating apparatus for heating an object.
Flame heating apparatus has many forms, one example of which is the domestic stove.
To take the case of the domestic stove, fuelled by gas or a liquid fuel, such as, kerosene, it is common experience that while heating an object, such as, a vessel containing a food substance, a part of the flame of the stove goes beyond the side of the vessel without remaining in contact with the vessel. To this extent, there is waste of fuel.
This invention therefore proposes a flame heating apparatus which does not allow any part of the flame to be rendered useless, by not remaining in contact with the vessel. Consequently the proposed apparatus saves fuel.

Other beneficial aspects of this invention will be apparent from the description appearing hereunder.
The fuel economising flame heating apparatus for heating an object, according to this invention, comprises a source of fuel; means connected to the said source for generating a flame for heating the object, characterized in that a guide vane assembly is provided around the flame; and a pump for sucking atmospheric air and directing such air against the flame for causing the flame to contact the object with respect to a specific surface area thereof to be heated.
This invention will now be described with reference to the accompanying drawings which illustrate, by way of example, and not of limitation, one of possible embodiments of the flame heating apparatus proposed herein, wherein
Fig. 1 illustrates a sectional view of a specimen of the known gas stove

Fig.2 illustrates a sectional view of the embodiment
Fig. 3 illustrates a separate view of the embodiment alone
Fig.4 illustrates a view of the embodiment with one kind of flame formation
And
Fig. 5 illustrates a view of the embodiment with another kind of flame formation (Mat formation)
The fuel economising flame heating apparatus for heating an object, is exemplified in the drawings as a gas stove K having a fuel tank F as a source of fuel.
Known means are connected to the fuel tank F for generating a flame J for heating the object. These means are exemplified in the drawings by a burner B receiving the fuel, which burns on

ignited to produce a flame J for heating an object which is exemplified by the vessel Z.
A guide vane assembly T is provided around the flame J and a pump P for sucking atmospheric air and directing such air (see arrows D) through jets Y of a tubular ring W, surrounding the flame J, against the flame J for causing the flame J to be directed towards the object, against the surface area to be heated. Thus no part of the flame J is allowed to go beyond the object which is exemplified in the drawings by a vessel Z. The jets Y are adjustable in position with respect to the guide vanes and the flame by means, such as, swivel joints by which such jets are connected.
According to one of possible forms of the guide vane assembly T, a plurality of flue gas guide vanes C and co-operating flame guide vanes H are placed around the flame J to contain the flue gas and the flame respectively to a specific area

These guide vanes C and H are adjustable in position, that is to say, the inclination of these guide vanes with respect to the flame J is adjustable, by means, such as linkage, in order to provide a predetermined inclination of the said vanes with respect to the flame J and the air from the pump P acting on the flame J, to achieve a desired formation of the flame.
In the drawings burner B has a through passage R for passage of the flue gases. The pump P sucks air from atmosphere, along with the hot flue gases in the passage R, through the said passage and pumps such air on to the flame J through the jets Y, thus utilizing the heat of the said flue gases..
Where there is no passage R in the burner B of another kind of stove the pump will still serve to direct air sucked direct from atmosphere on to the flame J.
Two of possible forms of the flame formations according to this invention are illustrated in Figs. 4 and 5. The former is a flame formation which ensures that the flame is in contact with a

specific area of the vessel. The latter is a flame formation, by which the flame takes on the shape of a mat M for achieving a contact with a larger surface area of the vessel.
