Economizers and heat recovery units

3. Economizers and heat recovery units (use of waste heat in gases as the heating medium)
3.1 Water or condensate “economizers” in combustion flue gas line (boilers, also condensation
boilers)
3.2 Steam superheaters in combustion flue gas line (boilers)
3.3 Heat recovery heat exchangers:
APPLICATION: Water/superheated water/oil heaters, recovering heat from Gas Turbines or Combustion motors flue gases
Water/superheated water/oil heaters, recovering heat from process gases
Air/gas heaters, recovering heat as above (In these units both sides are generally not pressure sides)
