Abstract
A device for producing a stable and augmented flame includes a fluid-inducing assembly and a shield. The fluid-inducing assembly includes a flow-diverting mechanism defining a flow-intake end and a flow-accelerating end and includes a plurality of vanes extending from the flow-intake end to the flow-accelerating end. The plurality of vanes is circumferentially disposed and spaced from one another. Furthermore, two vanes include a space defined therebetween, and the space defines a passage which is spiral-shaped. The flow-diverting mechanism further includes a covering member with an enclosed circumferential edge circumferentially surrounded. Thus, each vane in the flow-accelerating end is encircled by the covering member, and each vane in the flow-intake end is exposed to outside and not covered by the covering member. In addition, the shield is hollow and is disposed above the fluid-inducing assembly.
