全氢罩式炉废氢燃烧系统
摘要：
为解决现有技术中废氢烧嘴所存在的点火及燃烧状态不稳定的问题，本实用新型提供了一种全氢罩式炉废氢燃烧系统，它包括设置在加热罩(10)的烧嘴箱(8)上的废氢燃烧烧嘴(2)和与其连通的废氢燃烧空气管线(3)、废氢燃烧管线(4)，它还包括设置在加热罩的烧嘴箱上的主烧嘴和与其连通的主烧嘴阻隔用空气管线(5)、主烧嘴燃气管线(6)、主烧嘴燃烧用预热空气管线(7)；所述主烧嘴的火焰方向与内罩(9)的外壁相切，所述废氢燃烧烧嘴的火焰方向与主烧嘴的火焰方向成夹角。主烧嘴火焰区与废氢燃烧烧嘴火焰区相交，主烧嘴代替了传统的废氢燃烧系统的点火装置来点燃废氢燃烧烧嘴。本实用新型不但解决了废氢燃烧系统点火系统不稳定的问题，而且简化了废氢燃烧系统的设计，节约了设备投资。
摘要（英）：

The utility model provides a waste hydrogen combustion system for a full hydrogen bell type furnace, which aims to solve the problems of unsteady ignition and combustion state existing in a waste hydrogen burner in the prior art. The system comprises a waste hydrogen combustion burner (2) arranged on a burner box (8) of a heating mantle (10), a waste hydrogen combustion air pipeline (3) and a waste hydrogen combustion pipeline (4) which are communicated with the waste hydrogen combustion burner, a main burner arranged on the burner box of the heating mantle, as well as an air pipeline for the blocking of the main burner (5), a main burner fuel gas pipeline (6), and a preheating air pipeline for the combustion of the main burner (7), wherein the flame direction of the main burner is tangent to the outer wall of an inner cover (9), and the flame direction of the waste hydrogen combustion burner has an included angle with that of the main burner. A main burner flame zone intersects with a waste hydrogen combustion burner flame zone, and the main burner substitutes an ignition device of the prior waste hydrogen combustion system to ignite the waste hydrogen combustion burner. The utility model not only solves the unsteady problem of an ignition system of the waste hydrogen combustion system, but also simplifies the design of the waste hydrogen combustion system, and saves equipment investment.
