Benefits of technology
The present invention provides an improved flame for heating objects. This is achieved through a flared aperture which produces a smooth and continuous flame that covers the entire surface of the object. The flared aperture is uniform, without any interruptions, and the areas surrounding it are smooth. This results in better contact area and increased flame stability. This invention also reduces the likelihood of flashback and the time needed for the flame to fully extend during heating. Overall, this invention improves heat transfer and flame spread.
Problems solved by technology
Vertical nozzles do not provide a high degree of uniform heating when in contact with the bottom surface of a cooking utensil such as a pot or pan according to Tsung-Ming Hsu, so the solution is to configure vertical and slanted gas nozzles so that bias gas flow exhausted from the slanted nozzles are incorporated into straight gas flows exhausted from the vertical nozzles to form a spiraling concentrated gas flow within the burner head assembly.

Embodiment Construction
[0018]Now in reference to FIGS. 3 and 4, which are cut-away views of a vertical burner body 11, the interior slanting surface 16 of the flared lip 18 is lying opposite the distal portion 19 of the interior horizontal surface 22 of the top plate 15. Gas (meaning a mixture of gas and air) that is fed to a cylindrical body interior 12 is subjected to converging surfaces 16 and 19 creating a gas flow toward exhaustion at gap 17. Gap 17 is defined by the separation between the circular periphery 14 of the top plate 15 and the interior slanting surface 16 shown in FIG. 4.
[0019]According to the principles embodied in the present invention, the flared aperture 13 includes a projection beyond gap 17 illustrated by the projection 20 of the outward flared lip 18 in FIG. 4. This configuration provides that flue products are subjected to the interior slanting surface 16 outside the burner body.
[0020]In the preferred embodiment of the present invention, the outward flared lip 18 is configured to ...

A gas burner with a flared aperture is disclosed for exhausting gas from an upright cylindrical burner body having a closed bottom and an open top end defined by a flared lip. A circular top plate is positioned over the open top end and is spaced apart from the burner body so that the circular edge of the top plate overhangs a portion of the flared lip defining a uniform circular gap with smooth borders and without interruptions. A means for securing the top plate in spaced apart relationship to the burner body is provided so that a predetermined size of the uniform circular gap is obtained. The flared lip is configured to project beyond the uniform circular gap so that flu products from the burner body are subjected to the flared lip. A tube is connected to the burner body for delivering pressurized gas.
Description
BACKGROUND OF THE INVENTION[0001]The invention relates to a gas burner and improvement in flame properties for heating objects.PRIOR ART[0002]Flame properties of gas burners are a matter of concern in heating objects. For example, the inefficiency in using straight gas nozzles uniformly arranged to produce a uniform set of vertical flames was addressed in the U.S. Patent No. 2008 / 0,173,298 to Tsung-Ming Hsu. Vertical nozzles do not provide a high degree of uniform heating when in contact with the bottom surface of a cooking utensil such as a pot or pan according to Tsung-Ming Hsu, so the solution is to configure vertical and slanted gas nozzles so that bias gas flow exhausted from the slanted nozzles are incorporated into straight gas flows exhausted from the vertical nozzles to form a spiraling concentrated gas flow within the burner head assembly. This produces a high degree of uniformity in applying a flame to a heating surface.[0003]Furthermore, it has been found that heating ef...
