    • A furnace with a burner is disclosed. The burner may include an area expansion plenum, a burner tube, a heat exchanger, a gas valve, an igniter, and an induced-draft blower. The gas valve may meter gas into the area expansion plenum, while the induced-draft blower may draw air into the area expansion plenum, wherein air and gas may mix to produce a lean gas/air mixture. The lean gas/air mixture may then be pulled through the burner tube and into the heat exchanger. Within the heat exchanger, the lean gas/air mixture may be ignited and energy may be produced, exciting acoustic energy in the heat exchanger. The acoustic energy may be distributed out of the heat exchanger by the area expansion plenum. In order to distribute the acoustic energy, the cross sectional area of the area expansion plenum may be greater than the cross sectional area of the burner tube.
    • 公开了一种具有燃烧器的炉。 燃烧器可以包括区域膨胀增压室,燃烧器管,热交换器,气阀,点火器和引风机。 气阀可以将气体计量到区域膨胀增压室中,而引风机可以将空气吸入区域膨胀增压室,其中空气和气体可以混合以产生贫气/空气混合物。 然后可以将贫气/空气混合物拉过燃烧器管并进入热交换器。 在热交换器内,贫气/空气混合物可能被点燃并且可能产生能量,并在热交换器中激发声能。 声能可以由区域膨胀增压室分配出热交换器。 为了分配声能,区域膨胀增压室的横截面积可以大于燃烧器管的横截面面积。
