针对我国电站锅炉排烟温度偏高的情况，为了降低排烟温度，充分利用锅炉排烟余热，提出采用在锅炉尾部烟道加装低压省煤器技术以回收烟气余热，从而大幅度降低排烟温度。该装置可以研究不同换热器、低温省煤器等换热设备在气固流体换热中的换热特性，包括换热性能、污垢性能、腐蚀情况、积灰结焦等情况。
針對我國電站鍋爐排煙溫度偏高的情況，為瞭降低排煙溫度，充分利用鍋爐排煙餘熱，提齣採用在鍋爐尾部煙道加裝低壓省煤器技術以迴收煙氣餘熱，從而大幅度降低排煙溫度。該裝置可以研究不同換熱器、低溫省煤器等換熱設備在氣固流體換熱中的換熱特性，包括換熱性能、汙垢性能、腐蝕情況、積灰結焦等情況。

Aiming at the general high temperature o f e x h a u s t g a s i n d o m e s t i c p o w e r boilers,in order to reduce exhaust smoke temperature,make full use of the exhaust smoke waste heat boiler,In order to fur-ther make use of the power plant boiler exhaust heat,low pressure economizer technology in the boiler tail flue for heat recovery of flue gas was introduced,so as to reduce the exhaust temperature. The device can research different heat exchanger,heat exchange equipment such as low temperature economizer in gassolid fluid heat transfer characteristics of heat transfer,including heat transfer performance,the performance of the fo uling,corrosion product performance,dust deposition,and so on and so forth.
