水平焙烧的燃烧器
发明内容
根据一个实施方案，水平焙烧的燃烧器在燃烧体积中包括穿孔火焰保持器(PFH)，所述PFH包括由耐火瓦形成的多个竖直柱。燃料和燃烧空气源被构造成朝向PFH输出易燃燃料和空气混合物。PFH被构造成保持燃烧反应，所述燃烧反应邻近由耐火瓦形成的多个竖直柱中的每个。
附图说明
图1为根据一个实施方案的燃烧器的穿孔火焰保持器(PFH)设计的演变的图示。
图2为根据一个实施方案的安装的PFH的照片，其包括安装时的照片和操作中的照片。
图3为示出根据一个实施方案的图1和图2的PFH的绘图，包括详细视图。
具体实施方式
在以下具体实施方式中，参考形成本文一部分的附图。除非在上下文中另外指明，否则在附图中类似的符号通常表示类似的部件。在不脱离本发明的实质或范围的前提下，可采用其他实施方案和/或可进行其他更改。
图1为根据一个实施方案的燃烧器的穿孔火焰保持器(PFH)设计的演变的图示。图2为根据一个实施方案的安装的PFH的照片，其包括安装时的照片和操作中的照片。图3为示出图1和图2的PFH的绘图，包括详细视图。
参见图1-3，水平焙烧的燃烧器在燃烧体积中包括PFH，PFH包括由耐火瓦形成的多个竖直柱。燃料和燃烧空气源(未示出)中的至少一个被构造成朝向PFH输出易燃燃料和空气混合物。PFH被构造成保持燃烧反应，所述燃烧反应邻近由耐火瓦形成的多个竖直柱中的每个。
PFH可被构造成将燃烧反应保持在耐火瓦的多个竖直柱中的每个的上游、下游和旁边。
耐火瓦的至少一部分可包括穿孔耐火瓦。穿孔耐火瓦可被构造成将燃烧反应的至少一部分保持在每个穿孔耐火瓦的穿孔内。
相比于具有连续上游面的PFH，包括多个竖直柱的PFH借助于所述多个柱可提供增大的失效阻力。
虽然本文已经公开了多个方面和实施方案，但也可设想其他方面和实施方案。本文所公开的各个方面和实施方案出于说明性目的，而并非旨在进行限制，真实范围和实质由以下权利要求书指示。
