SYSTEM AND METHOD FOR IMPROVING THE PERFORMANCE OF A SELECTIVE CATALYST REDUCTION SYSTEM IN A HEAT RECOVERY STEAM GENERATOR
摘要：
A heat recovery steam generator (10) includes a gas inlet (12) for receiving a flow of exhaust gas (14) from a gas turbine (18), a gas outlet (34) opposite the gas inlet (12) and configured to transport the flow of exhaust gas (14) to atmosphere, and a sorbent injection device (58) intermediate the gas inlet (12) and the gas outlet (34), the sorbent injection device (58) including at least one injection port (54) configured to inject a sorbent (66) into the flow of exhaust gas (14). The sorbent (66) is configured to react with an acid gas within the flow of exhaust gas (14) to neutralize the acid gas and inhibit the formation of salt deposits.
摘要（中）：

热回收蒸汽发生器（10）包括用于接收来自燃气轮机（18）的排气流（14）的气体入口（12），与气体入口（12）相对并且被配置为传送 （14）到大气的流动以及在所述气体入口（12）和所述气体出口（34）中间的吸附剂注射装置（58），所述吸附剂注射装置（58）包括至少一个注射端口（54） 配置成将吸附剂（66）注入排气流（14）中。 吸附剂（66）被配置为与排气流（14）内的酸性气体反应以中和酸性气体并抑制盐沉积物的形成。
