摘要： PROBLEM TO BE SOLVED: To provide an exhaust gas denitrizer capable of using a high temperature exhaust gas and using an NH 3 injection device in which problem of clogging of NH 3 water injection nozzle is not generated even when a sulfur oxide is contained in the exhaust gas, and a method. SOLUTION: In the exhaust gas denitrizer, compressed air is fed from a blower 8 to an ejector 7 for extracting the exhaust gas from HRSG (heat recovery boiler) 1, and NH 3 water is produced by obtained mixing gas and NH 3 -containing gas is produced by an NH 3 water evaporator 10 and is injected by an NH 3 -containing gas injection nozzle 3 of the HRSG1 on the upstream side of a nitration catalyst layer 2. Since the high temperature exhaust gas is cooled and diluted by compressed air, there is no fear that the NH 3 is oxidized in a process that the NH 3 water is evaporated. Concentration of moisture content in the exhaust gas is reduced and generation of drain in the exhaust gas extract pipe can be inhibited. Warming in an evaporation system of NH 3 water can be early carried out and temperature of NH 3 -containing gas obtained by evaporation of the NH 3 water can be lowered. Since reduction of thermal stress of the NH 3 -containing gas pipe system can be easily carried out, denitrization of the exhaust gas can be easily carried out. COPYRIGHT: (C)2005,JPO&NCIPI
摘要翻译：要解决的问题：为了提供能够使用高温废气并使用NH 3 SB 3注射装置的排气脱硝器，其中NH 3 SBB阻塞问题即使在排气中含有硫氧化物也不会产生喷水喷嘴，也可以是一种方法。解决方案：在废气脱硝机中，将压缩空气从鼓风机8供给到用于从HRSG（热回收锅炉）1抽出废气的喷射器7，并且产生NH 3 水通过得到的混合气体和含NH 3 SB 3气体由NH 3 SBB水蒸发器10产生，并通过含NH 3 SB 3气体 HRSG1的喷射喷嘴3在硝化催化剂层2的上游侧。由于高温废气被压缩空气冷却和稀释，所以不必担心NH 3 SB 3在处理NH 3 SB 3水蒸发。排气中的水分含量降低，排气提取管中的排水的产生被抑制。可以早期进行NH 3 SB 3水蒸发系统的升温，并通过NH 3 SB 3蒸发得到的包含NH 3 / SB 3气体的温度，水可以降低。由于可以容易地进行含有含NH 3 SB 3气体管道系统的热应力的降低，所以可以容易地进行排气的脱硝。版权所有（C）2005，JPO＆NCIPI
