Heat Recovery Systems

for optimum fuel efficiency


The energy saving potential is shown
in attached graf.

The different air preheat temperatures provide a fuel saving up to 50 percent.

With a flue gas inlet temperature 
of 1450º C a HTG® recuperator can provide an air preheat temperature 
up to 800º C.


The advantages with a recuperator
system are:

  • A fuel saving potential up to 
50 percent
  • Better operating flexibility compared
 with a regenerative system
  • Lower NOx emission
  • Lower weight and smaller dimensions
 – compared with a regenerative system
  • Lower sensitivity against fouling
