[0003] 本申请是主张2008年9月22日提出申请的美国临时专利申请第61/099,200号的优先权的正式申请。 [0003] This application claims priority to US provisional patent is filed September 22, 2008 filed a formal application No. 61 / 099,200.

技术领域 FIELD

[0004] 本发明涉及燃烧器,并且更具体地涉及使空气或氧气与气态或蒸发燃料混合的燃 [0004] The present invention relates to combustors, and more particularly to air or oxygen and the gaseous fuel or fuel mixture evaporated

背景技术 Background technique

[0005] 使用气态燃料或液态燃料的燃烧器用于包括锅炉、管式加热器、炉子、其它燃气用具的许多应用以及其它应用中。 [0005] The use of liquid fuel or gaseous fuel burner for a boiler comprising, tubular heaters, furnaces, many other applications and other applications in gas appliances. 基本上,这些燃烧器将气态燃料或液态燃料引入到空气或氧气流中。 Basically, these gaseous fuel burner or liquid fuel into a stream of air or oxygen. 如果使用液态燃料,必须蒸发或雾化该液态燃料。 If a liquid fuel, the liquid must be evaporated or atomized fuel. 首先,点燃产生的燃料和空气或氧气流并使该燃料和空气或氧气流作为可见火焰或作为极热气体混合物流离开燃烧器的喷嘴。 First, the fuel and ignited to produce air or oxygen stream and the fuel and air or oxygen gas stream as a visible flame or very hot gas stream leaving the mixing nozzle of the burner.

[0006] 为了试图提高例如锅炉、管式加热器、炉子及其它燃气用具的不同应用中的现有技术的水平,进行详细的研究以使这些上述领域中的每一个中的现有技术水平合格并量化该现有技术水平。 [0006] In an attempt to improve the level of different applications, for example boilers, tubular heaters, furnaces, and other gas appliances in the prior art, detailed studies of the art so that each of these above-mentioned areas in conformity and quantify the level of prior art. 研究毫无例外地表明可以对这些领域中的每一个,特别是减少操作成本并减少或消除排放物进行改进。 Studies show that without exception, can each of these areas, in particular to reduce operating costs and reduce or eliminate emissions improvement. 在目前的世界市场中,操作成本和诸如减少或消除排放物的环境问题通常是最显著争论点的中的两个,甚至是大多数行业所面临的最显著的争论点。 In the current world market, operating costs and reduce or eliminate environmental problems such as emissions are usually two of the most significant issues, even the most significant issue facing most industries.

[0007] 值得注意地,在现有技术中显而易见的是对使用燃烧器以产生热量的这些各种类型的装置进行的可能的改进最终不会导致显著地改进。 [0007] Notably, in the prior art become apparent it is possible to improve the various types of devices for such a burner to produce heat is eventually not lead to significantly improved. 在现有技术中显而易见的是,毫无例外地,这些各种类型装置中的基本问题在于燃烧器的效率低。 Apparent in the prior art are, without exception, the basic problem with these types of devices is the low efficiency of the burner. 大多数现有技术的燃烧器的效率仅在大约60% _70%。 Most of the efficiency of the burner in the prior art only about 60% _70%. 燃料的不完全燃烧是所有这些装置所固有的主要问题。 Incomplete combustion of the fuel is a major problem inherent in all of these devices. 此外,燃烧效率低的这种问题是导致行业中以上所述两个显著成本(即,操作成本和环境问题)的主要原因。 Furthermore, this problem of low combustion efficiency results in the industry more than two significant cost (i.e., operating cost and environmental issues) the main reason.

[0008] 因此,为了根本上改进诸如锅炉、管式加热器、炉子及其它燃气用具的装置,已经发现必须使燃烧器技术的设计具有显著和基本的进步。 [0008] Accordingly, in order to fundamentally device such as a boiler, tubular heaters, furnaces, and other gas appliances improvements, it has been found necessary to design the burner has significant technical and fundamental progress. 更具体地,为了最大化锅炉、管式加热器、炉子及其它燃气用具的设计,根据成本、效率等,需要根本上重新设计为所述锅炉、管式加热器、炉子及其它燃气用具提供动力的燃烧器。 More specifically, in order to maximize the boiler, tube heaters, furnaces, and other gas appliances design, according to cost and efficiency, is a fundamental redesign of the boiler, tube heaters, furnaces, and other gas appliances powered burner. 如果用于这些设备的燃烧器可以防止低效率,则不用改善锅炉技术、管线加热炉技术、熔炉技术等等。 If these devices for burners prevents inefficient, do not improve the boiler technology, line art furnace, the furnace technologies.

[0009] 要注意的是已经试图对各种类型的燃烧器的这种改进在各种领域中已经进行了许多年,但没有显著的成就。 [0009] Note that this improvement has been attempted various types of burners have been carried out for many years in a variety of fields, but no significant achievement. 因此,通常对燃烧器系统和使用燃烧器的装置进行其它方面的改善。 Thus, typically to improve other aspects of the burner system and apparatus using the burner.

[0010] 用于克服排放物的环境问题的最通常的设计改进为使废气再循环。 [0010] The most commonly designed to overcome the environmental problems to improve the emissions of the exhaust gas recirculation. 总之,已经发现废气的再循环可以用于减少燃烧器系统的整个排放物。 In summary, it has been found that the recirculated exhaust gas may be used to reduce the overall emissions of the burner system. 然而,具有与这种废气的再循环相关联的问题。 However, a problem with such an exhaust gas recirculation associated. 最显著的问题在于废气的再循环基本上会增加使燃烧空气和添加的废气的混合物流通过系统所需的能量。 The most significant problem is that the recirculated exhaust gas stream substantially increases the mixing of combustion air and exhaust gas through the system to add the desired energy. 例如,通常从排出返回到燃烧器的百分之十(10%)的废气再循环的增加通常会导致迫使空气进入燃烧器系统的风扇所述的功率增加大约40% -45%。 For example, usually returned from the discharge to the combustor is increased ten (10) percent exhaust gas recirculation generally results in the power of the fan forces air into the burner system is increased by about 40% -45%. 显而易见地,与根据效率并因此根据成本得到的解决方案相比较,这种解决方案是不易被接受的。 Obviously, in accordance with the comparison of the relative efficiency and thus the cost of the resulting solution, this solution is difficult to be accepted. 在考虑大多数废气多次通过燃烧器系统是这尤其不易被接受。 Most of the exhaust gas by considering the multiple burner system which is especially difficult to be accepted.

[0011] 具有一种使用来自高速燃烧空气射流的能量以促进燃烧器系统内再循环的燃烧器系统。 [0011] for use with high-speed energy from the combustion air jets to promote recirculation system within the combustor burner system. 这种技术的可行性取决于许多因素,并且如果使用这种技术通常更加难以使相当大的一部分燃烧产物返回到燃烧器,从而使得在许多情况下难以采用该技术。 Feasibility of this technique depends on many factors, and if this technique is generally more difficult to make a substantial portion of the combustion products to return to the burner, making it difficult to use this technique in many cases.

[0012] 清楚的是使废气再循环以改进排放物不是一种改进燃烧器系统的设计的可行方案。 [0012] It is clear that in order to improve the exhaust gas recirculation is not a viable option for an improved emissions burner system design. 在燃料通过燃烧器系统的情况下使燃料尽可能有效率地燃烧是唯一合理的解决方案;然而,不存在理想的有效的燃烧器。 In the case of the fuel by the fuel burner system as efficiently as possible combustion is the only reasonable solution; however, there is no effective over a burner.

[0013] 只有燃烧器和燃烧器技术的基本重新设计将导致产生低排放物的有效燃烧器。 [0013] Only substantially redesigned burner and burner technology will lead to effective low-emissions combustors. 燃烧器的基本技术在最近几十年没有显著变化。 The basic technology in recent decades the burner did not change significantly. 现有技术的研究已经揭示了根据效率和排放物的被公知为相对有效但没有随后所述的本发明有效率的燃烧器的两个示例。 Study of the prior art has revealed two well-known example of the efficiency and the emission efficiency of the burner of the present invention is relatively efficient, but not subsequently described.

[0103] 已经发现的是宽空气储存室70与空气接收入口72和窄空气流出口74 —起有助于空气从大致环形空气流动混合室100移动到螺旋形空气流动通道90。 [0103] It has been found that the width of the air storage chamber 70 and the air inlet 72 receiving the air flow and a narrow outlet 74-- facilitate air from moving from the substantially annular airflow mixing chamber 100 in the spiral air flow passage 90. 空气流出口74的横截面面积当相对于纵向轴线“L”横向测量时比宽空气储存室70的横截面面积窄。 An air flow outlet 74 when the cross-sectional area relative to the longitudinal axis "L" is narrower than the wider the area of ​​the air storage chamber 70 of the transverse cross-section measurement.

[0104] 在使用中,参照图38,空气通过至少一个空气入口38和第二空气入口39进入空气流动控制后壳体30,并且首先聚集在大致环形空气聚集室29中。 [0104] In use, referring to FIG. 38, 38 and the second air inlet 39 air enters the housing 30 through the air flow control at least one air inlet, and a substantially annular first accumulated in the air accumulation chamber 29. 空气从大致环形空气聚集室29经由第一空气流动开口101、第二空气流动开口102、第三空气流动开口103和第四空气流动开口104通到大致环形空气流动混合室100,第一空气流动开口101、第二空气流动开口102、第三空气流动开口103和第四空气流动开口104的偏移深度以四个不同且独立的“水平”(相对于纵向轴线“L”)使空气进入大致环形空气流动混合室100,从而产生非层流空气。 A substantially annular air from the air accumulation chamber 29 via a first air flow opening 101, a second air flow opening 102, the third air flow opening 103 and the fourth air flow opening 104 opens into a substantially annular air-flow mixing chamber 100, a first air flow opening 101, the second air flow opening 102, the third air flow opening 103 and the fourth air flow opening 104 in the depth offset four different and independent "horizontal" (relative to the longitudinal axis "L") substantially air into the annular air flow mixing chamber 100, thereby generating a non-laminar air flow. 依此方式,空气被尽可能地扰动,以便有助于下游空气与来自燃料喷嘴末端60的燃料完全混合。 In this manner, air is disturbed as much as possible, to facilitate downstream air fuel from the fuel nozzle tip 60 is completely mixed. 空气然后通过宽空气储存室70,通过窄空气流出口74离开,这促进空气的流动。 The air is then by the wide air storage chamber 70, the air flow 74 exits through the narrow outlet, which promotes the flow of air.

[0105] 接下来,来自宽空气储存室70的空气在即将被喷出到燃烧器20的混合室80之前必须进入并通过第一空气流动通道90a、第二空气流动通道90b、第三空气流动通道90c、第四空气流动通道90d和第五空气流动通道90e。 [0105] Next, the air from the air storage chamber 70 is wide in the combustor is about to be discharged into the mixing chamber 20 must flow into and through the first air passage 80 before the 90a, 90b of the second air flow passage, the third air flow channel 90c, fourth 90d and fifth air flow passage air flow passage 90e. 快速空气流然后通过大致直的燃料喷嘴50的细长主体55的出口端57并通过燃料喷嘴末端60,然后与从燃料喷嘴末端60流出的燃料混合。 Fast air flow through the elongate body and a substantially straight outlet 55 of the fuel nozzle 50 through the end 57 of the fuel nozzle tip 60, and then mixed with the fuel flowing from the fuel nozzle tip 60. 由于五个空气流动通道90a、90b、90c、90d和90e的横截面面积从入口91到出口92的减少,空气以比该空气进入入口91的速度明显较高的速率离开出口92。 Since the five air flow passages 90a, 90b, 90c, 90d and 90e of the cross-sectional area decreases from the inlet 91 to the outlet 92, the air velocity than the air entering the inlet 91 at a rate significantly higher exiting the outlet 92.
