High-temperature resistant plate-type air preheater for flue gas recovery
Thread Content
I would like to ask the experienced colleagues: with flue gas at a high temperature of 1000°C and a flow rate of 1000 m3/h, can a fully welded plate-type air preheater be used to preheat the air to above 500 degrees Celsius? How much heat exchange area is needed? Will the high-temperature resistant material 310S work?
Fully welded plate type is not suitable for this operating condition
The chemical reactivity of combustion flue gases is complex, and it is estimated to have a significant impact on the lifespan and stability of equipment. The structural design of the plate exchanger is likely to fail to meet the requirements for long-term use.
Plate-type ones won’t work, right? At high temperatures, deformation of the plate doesn’t necessarily lead to any problems
At such high temperatures, a heat pipe exchanger can be considered
