一． 结构简介、主要规范
Brief introduction of structure and main specifications
ZFQ-5.0-2.35-00系列蒸汽发生器应用于烟道气的余热回收，整体系统由蒸汽过热器、水管蒸发器、热管软水预热器、和蒸汽聚集器四部分组成，其间由汽水循环管道连接。
ZFQ-5.0-2.35-00 series of steam generator is applied to the waste heat recovery of flue gas. The whole system consists of the steam supurheater, the tube evaporator, the heat-pipe soft-water preheater and the steam accumulator; which are connected through the steam circulation piping.
蒸汽过热器利用高温余热，水管蒸发器和热管软水预热器回收中低温余热，分别利用列管换热器和热管换热器的优势，保证装置稳定运行，充分回收余热。
The steam superheater uses the high-temperature waste heat; the tube evaporator and the heat-pipe soft-water preheater recover the medium-and-low-temperature waste heat and they take advantages of the shell-and-tube heat exchanger and the heat-pipe heat exchanger respectively to ensure the steady operation of device and full recovery of the waste heat.
1. 蒸汽过热器：
1. Steam superheater:
该设备为第一级换热设备，主要由列管管束、蒸汽进出口集箱和烟箱组成。蒸汽走管束内，烟气走管束外。以列管管束为换热元件，烟气环绕管束外壁，从而将热量不断输送给管内冷介质，产生过热蒸汽。
This equipment is the first-step heat exchange equipment and mainly consists of the tube bank, the steam entrance and exit header and the smoke box. The steam moves within the tube bank and the flue gas moves outside of the tube bank. With the tube bank as the heat exchange element, the flue gas surrounds the outer wall of the tube bank and transfers the heat to the cold medium within the tube so as to produce superheat steam.

2. 水管蒸发器
2. Tube evaporator:
该设备为第二级换热设备，主要由列管管束、软水进出联箱和烟箱组成。软水走管束内，烟气走烟箱。以列管管束为换热元件，烟气环绕管束外壁，从而将热量不断输送给管内冷介质，产生压力为2.35MPa饱和蒸汽，入蒸汽聚集器进行汽水分离。
This equipment is the second-step heat exchange equipment and mainly consists of the tube bank, the soft-water entrance and exit header and the smoke box. The soft water moves within the tube bank and the flue gas moves within the smoke box. With the tube bank as the heat exchange element, the flue gas surrounds the outer wall of the tube bank and transfers the heat to the cold medium within the tube so as to produce 2.35MPa saturated steam, which enters the steam accumulator to separate the steam.
3.热管式软水换热器：
3. Heat-pipe soft-water exchanger:
该设备为第三级换热设备，主要由径向热管、管板和烟箱组成。热管作为传热元件，其两端焊接于两端管板，中间热管置于烟箱内，软水走径向热管内，烟气走烟箱。热管将烟气中热量输送给热管内冷介质，产生高温软水，进入蒸汽聚集器进行补水。从而完成换热，将烟气温度降低排放。
This equipment is the third-step heat exchange equipment and mainly consists of the radial heat pipe, the tube plate and the smoke box. With the heat pipe as the heat transfer element, its both ends are welded to both ends of the tube plate and the middle part of the heat pipe is within the smoke box; the soft water moves within the radial heat pipe and the flue gas moves within the smoke box. The heat pipe transfers the heat within the flue gas to the cold medium within the heat pipe, produces high-temperature soft water and enters the steam accumulator to compensate water. So the heat exchange is finished and the flue gas is emitted after its temperature is lowered.
4. 蒸汽聚集器：
4. Steam accumulator:
水管蒸发器产生的饱和蒸汽经上循环管进入蒸汽聚集器，进行汽水分离，蒸汽排出，软水经下循环管进入水管蒸发器，往复循环。热管软水预热器产生的软水进入蒸汽聚集器进行补水。
The saturated steam produced by the tube evaporator goes through the upper circulating pipe and enters the steam accumulator to separate the steam. The steam is exhausted, the soft water goes through the lower circulating pipe and enters the tube evaporator and circulates again and again. The soft water produced by the heat-pipe soft-water preheater enters the steam accumulator to compensate water.
