    • A swirl-type internal flame recirculation burner as used to fire asphalt plant aggregate dryers, air heaters and calcining kilns and method includes an atomizer assembly for swirling primary air in two concentric streams with the inner stream swirling more rapidly than the outer stream. Fuel oil is blast atomized in a continuous sheet into the inner stream without prefilming and then is shear atomized as the inner and outer streams violently intermix. The burning and swirling fuel and primary air mixture recirculates upstream along the burner axis. Secondary air is swirled in the same direction as the primary air and surrounds the primary air stream to promote further mixing and internal recirculation. A metal frustro-conical flame holder surrounds the burner head to stabilize and shape the recirculation flame and shield low-burn flames from tertiary air. The swirl of the secondary air is also adjusted to shape the flame. The burner may also be fired on gas or a combination of gas and oil.
    • 用于消除沥青混合料干粉机,空气加热器和煅烧窑的旋流式内部火焰再循环燃烧器和方法包括:雾化器组件,用于以两个同心流旋转一次空气,其内流比外流更快地旋转。 燃料油在连续片材中喷射雾化到内部流中而没有预先制备,然后随着内部和外部流体剧烈混合而被剪切雾化。 燃烧和旋转的燃料和一次空气混合物沿着燃烧器轴线向上游再循环。 二次空气以与一次空气相同的方向旋转并且围绕一次空气流以促进进一步的混合和内部再循环。 金属截头圆锥形火焰保持器围绕燃烧器头部,以稳定和塑造再循环火焰,并从三次空气屏蔽低燃烧火焰。 二次空气的漩涡也被调节成使火焰成型。 燃烧器也可以在气体或气体和油的组合上燃烧。

    • A U-tube diffusion flame burner assembly having improved flame stabilization with no undesirable acoustic effects. The burners are axial units comprised of flame holders and combustors. The flame holders includes secondary air tubes to support the flow of secondary air that have helical walls forming helical passageways along at least a portion of its inner diameter to impart a swirl to the secondary air. The helical passageways impart a swirl to the secondary air exiting the passageways while simultaneously acting as a heat exchanger to heat primary air. The flame holders includes fuel tubes having first ends connected to a fuel supply and second flame ends. A plurality of radially oriented apertures are located at the second flame ends to distribute fuel in a radial direction. Primary air tube surrounds at least the flame ends of the fuel tubes and extend axially from first air supply ends to second flame ends. Air is diverted from air supply ends of the flame burners into primary air tubes through radial apertures located at the first air supply ends of the primary air tubes. Secondary air tubes surround the primary air tubes extending from first air supply ends to second ends opposite the air supply, the secondary air tubes having inner diameters larger than the outer diameters of the primary air tubes. The secondary air tubes extend for a preselected distance beyond the second flame ends of the primary air tubes and are coupled to axially-oriented conical-shaped reducers. Flame at high velocity exits the restricted end of the reducers.
    • 一种具有改进的火焰稳定性而没有不期望的声学效应的U型管扩散火焰燃烧器组件。 燃烧器是由火焰保持器和燃烧器组成的轴向单元。 火焰保持器包括二次空气管,以支撑二次空气的流动,所述二次空气的流动具有沿着其内径的至少一部分形成螺旋形通道的螺旋壁,以向二次空气施加漩涡。 螺旋通道对离开通道的二次空气施加涡流,同时作为热交换器来加热一次空气。 火焰保持器包括具有连接到燃料供应端和第二火焰端的第一端的燃料管。 多个径向定向的孔位于第二火焰端,以沿径向方向分配燃料。 主空气管至少包围燃料管的火焰端,并从第一供气端轴向延伸到第二火焰端。 空气从火焰燃烧器的空气供应端通过位于主空气管的第一空气供应端的径向孔转入主空气管。 二次空气管围绕从第一供气端延伸到与供气相对的第二端的主空气管,二次空气管的内径大于一次空气管的外径。 二次空气管延伸超过主空气管的第二火焰端的预选距离,并且连接到轴向定向的圆锥形减速器。 火焰以高速度离开减速机的受限制端。

    • A camera locks out an attempted flash photograph when the voltage of the flash charger is below a minimum voltage necessary for the flash to fire. Flash lockout may also take place when: the flash charger voltage is equal to or greater than the minimum flash voltage but less than the lowest voltage in a voltage range providing optimum flash lighting; and the photographic subject distance is beyond the flash range at the present flash charger voltage. Lockout may also be determined based on current flash charger charging time compared to predetermined times for the flash charger to reach the minimum voltage and/or the lowest voltage in the optimum lighting range from a substantially discharged state.
    • 当闪光灯充电器的电压低于闪光灯所需的最小电压时,相机会锁定尝试的闪光照片。 当闪光灯充电器电压等于或大于最小闪光电压但小于提供最佳闪光照明的电压范围内的最低电压时,闪光灯锁定也可能发生; 并且拍摄对象的距离超过了闪光灯充电器电压下的闪光范围。 也可以基于当前的闪光灯充电器充电时间来确定锁定,与闪光充电器的预定时间相比,从基本上放电状态到达最佳照明范围内的最小电压和/或最低电压。
