空气预热器旁路式烟气余热梯级利用系统
摘要：
空气预热器旁路式烟气余热梯级利用系统，包括安装在空气预热器入口与电除尘器入口之间的旁路烟道上的烟气换热器，安装在烟气换热器入口的循环泵，安装在给水泵出口旁路管道上的分级加热器；循环泵将部分凝结水升压后接入烟气换热器中吸热烟气余热，升温后的凝结水接入分级加热器中将部分热量释放给旁路给水，放热后的凝结水由除氧器入口管道引回回热系统，从而实现了烟气余热逐级加热高压给水和低压凝结水的目的，即烟气余热梯级利用。
摘要（英）：

Air heater bypass formula flue gas waste heat cascade utilization system includes the gas gas heater on the by -pass flue who installs between air heater entry and electrostatic precipitator entry, installs the circulating pump at the gas gas heater entry, installs the bleeding ware on water -feeding pump export bypass pipeline, insert heat absorption flue gas waste heat among the gas gas heater after the circulating pump steps up partial condensate water, condensate water after the intensification in inserting the bleeding ware releases partial heat for the bypass feedwater, and the condensate water after exothermic draws back heat recovery system by oxygen -eliminating device inlet pipe to realized that the flue gas waste heat adds the purpose of thermal high feedwater and low pressure condensate water, flue gas waste heat cascade utilization promptly step by step.
