专利汇可以提供Burner means for thermoelectric generator专利检索，专利查询，专利分析的服务。并且An improved burner assembly, especially useful to heat a thermoelectric generator, comprising an ultrasonic atomizer for atomizing liquid fossil fuels into a mist of fine particles; baffle means for causing an appropriate mixture of fuel and air; and, usually, a mantle for uniformly distributing the heat of combustion over a cylindrical hot plate against which thermoelectric legs are disposed.，下面是Burner means for thermoelectric generator专利的具体信息内容。
1. In a thermoelectric generator comprising a hot plate against which thermoelectric legs are disposed, improved burner means for heating said hot plate comprising, in alignment with said hot plate on a central axis, (A) blower means spaced on said axis from said hot plate and arranged to blow an oxidizing gas along said axis toward the hot plate; (B) an ultrasonic atomizer downstream from the blower means, connected to a source of liquid fuel, and having a vibrating horn located on said axis from which the fuel emanates downstream as a fine mist, (C) a cylindrical wall spaced radially around said horn and in line with said blower means so as to convey said oxidizing gas downstream from said blower means past said horn; and (D) baffle means disposed around said horn and consisting essentially of a set of overlapping vanes that are attached to the inside of said wall, extend radially toward said axis, and are disposed at an angle to said axis so as to form a first part of the oxidizing gas that is conveyed downstream by the cylindrical wall into a vortex; the innermost edge of the vanes being adjacent to, but spaced from, said horn so as to define an area through which a second part of said oxidizing gas passes unimpeded; and at least part of the outermost edge of the vanes being spaced from the cylindrical wall so as to permit a third part of said oxidizing gas to pass unimpeded along the wall so as to contain said vortex into a compact area, whereby the flame of fuel supplied by said ultrasonic atomizer is kept compact.
2. In a generator of claim 1 in which the hot plate is cylindrical, a cylindrical burner housing aligned on said axis and extending from said cylindrical wall, and a cylindrical, closed-end mantle aligned on said axis, connected through an opening to said burner housing, and juxtaposed within said cylindrical hot plate; the mantle comprising a solid cylindrical wall perforated by a set of holes distributed over the mantle so as to cause a uniform heating of the hot plate.
3. A generator of claim 1 in which the vanes are disposed at an angle between about 20* and 70* to said axis.
4. A generator of claim 1 in which the vanes are disposed at an angle between about 40* and 60* to said axis.
5. A generator of claim 1 in which the total surface area on one side of the vanes is 1.6 times as great as the area subtended by the vanes.
6. A generator of claim 1 in which the downstream part of the vanes curves inwardly toward said axis from the point of connection of the vanes to the cylindrical wall.
7. In a thermoelectric generator comprising a cylindrical hot plate against which thermoelectric legs are disposed, improved burner means for heating said cylindrical hot plate comprising, in alignment with said cylindrical hot plate on a central axis, (A) blower means spaced on said axis from said hot plate and arranged to blow an oxidizing gas along said axis toward the hot plate; (B) an ultrasonic atomizer downstream from the blower means, connected to a source of liquid fuel, and having a vibrating horn located on said axis from which the fuel emanates downstream as a fine mist; (C) a cylindrical wall spaced radially around said horn and in line with said blower means so as to convey said oxidizing gas downstream from said blower means past said horn; (D) baffle means disposed around said horn and consisting essentially of a set of overlapping vanes that are attached to the inside of said wall, extend radially toward said axis, have a total surface area on one side equal to at least about 1.6 times the area subtended by the vanes, and are disposed at an angle of between about 20* and 70* to said axis so as to form a first part of the oxidiziNg gas that is conveyed downstream by the cylindrical wall into a vortex; the innermost edge of the vanes being adjacent to, but spaced from, said horn so as to define an area through which a second part of said oxidizing gas passes unimpeded; and at least part of the outermost edge of the vanes being spaced from the cylindrical wall so as to permit a third part of said oxidizing gas to pass unimpeded along the wall so as to contain said vortex into a compact area, whereby the flame of fuel supplied by said ultrasonic atomizer is kept compact; (E) a cylindrical burner housing aligned on said axis and extending from said cylindrical wall; and (F) a cylindrical, closed-end mantle aligned on said axis, connected to said burner housing, and juxtaposed within said cylindrical hot plate; the mantle comprising a solid cylindrical wall perforated by a set of holes distributed over the mantle so as to cause a uniform heating of the hot plate.
8. A generator of claim 7 in which the vanes are disposed at an angle between about 40* and 60* to said axis.
9. A generator of claim 7 in which the downstream part of the vanes curves inwardly toward said axis from the point of connection of the vanes to the cylindrical wall.
