RENEWABLE ENERGY - HEAT RECOVERY FROM WASTE WATER


Heat exchangers


 

Next to the right material choice, type and manufacture of the heat exchanger are decisive for its useful life. Not all manfacturing processes are equally suitable. A useful life > 40 years is expected from lingitudinally weldet structures.

Longitudinally structures   Inflatable structures   Welded structures
   
 
++ Proneness to faults / structural weaknesses (ratio of surface to welded surface)
++ Material thickness freely selectable
-

Turbulent flow
(i
n heat exchanger)

++ Setting of the residence time (free choice of the dimensions)
++ Pressure loss
- Ratio of max. pressure to operating pressure (factor 1.5)
+ Danger of corrosion in the HE
++ Useful life
   
+ Proneness to faults / structural weaknesses (ratio of surface to welded surface)
- Material thickness freely selectable
++ Turbulent flow
(in heat exchanger)
+ Setting of the residence time (free choice of the dimensions)
+ Pressure loss
++ Ratio of max. pressure to operating pressure (factor 10)
++ Danger of corrosion in the HE
+ Useful life
