    • An ejector, such as a venturi, facilitates the delivery of gaseous fuel to the combustion chamber of a burner. A blower forces air through the ejector, and the air flow produces a suction that draws fuel from a fuel inlet to produce a fuel-air mixture. The amount of fuel drawn from the fuel inlet is a function of the air flow such that a substantially constant fuel-air ratio is obtained over a range of air flow rates and temperatures without the need for a separate high-pressure fuel pump. The fuel-air mixture may be provided to a combustion chamber for combustion. Air from the blower may be pre-heated prior to entering the ejector, for example, using a heat exchanger that recovers some of the heat from the combusted fuel-air mixture. Air flow through the ejector may be conditioned, for example, by a swirler, to produce a tangential air flow that can increase fuel flow by increasing air velocity across the fuel inlet and/or produce a swirl-stabilized flame in the combustion chamber. The combusted fuel-air mixture may be provided to a thermal load, such as an external combustion engine. Blower speed may be controlled manually or automatically to control power output. Fuel flow to the ejector can be controlled manually or automatically to control fuel-air ratio. The burner can be configured to operate with multiple fuel types, for example, using a fuel selector with fixed or variable restrictors.
    • 诸如文氏管的喷射器有助于将气体燃料输送到燃烧器的燃烧室。 鼓风机迫使空气通过喷射器,并且空气流产生抽吸,其从燃料入口抽取燃料以产生燃料 - 空气混合物。 从燃料入口抽出的燃料量是空气流量的函数,使得在空气流量和温度的范围内获得基本恒定的燃料空气比,而不需要单独的高压燃料泵。 燃料 - 空气混合物可以被提供到用于燃烧的燃烧室。 来自鼓风机的空气可以在进入喷射器之前预热,例如,使用从燃烧的燃料 - 空气混合物回收一些热量的热交换器。 通过喷射器的空气流可以例如通过旋流器进行调节,以产生切向空气流,其可以通过增加穿过燃料入口的空气速度和/或在燃烧室中产生涡流稳定的火焰来增加燃料流量。 燃烧的燃料 - 空气混合物可以被提供给诸如外燃机的热负荷。 鼓风机速度可以手动或自动控制,以控制输出功率。 可以手动或自动控制到喷射器的燃料流量,以控制燃油比。 燃烧器可以被配置为使用多种燃料类型操作,例如使用具有固定或可变节流器的燃料选择器。
