Boiler Exhaust Gas Economizer
Cost - Free Hot Water
The system is designed to recover the energy of the exhaust gas at about 180 - 200 ºC, which is discharged from the steam generators and steam boilers
Technical Details
Economizer is manufactured with cartridge type heat exchangers, so that they can be repaired and renewed separately.

Working Principles
Stenters and relax dryers are atmospheric machines and as air is discharged from the
chimney, the same amount of fresh and cold air enters inside the system.
-
Two-stage economizer is used for maximum energy recovery.
-
In the first stage boiler feeding water is heated.
-
Process water is heated in the second stage.
-
As the exhaust gas is directed downwards inside the economizer, the
-
condensate particles do not rest on the heat exchangers so that
corrosion is minimized. -
In the system, there is a condensate collection tank of stainless steel
with appropriate discharge system. -
Boiler exhaust gas is directed to the economizer with a connection to
the existing chimney. -
There is a flap system which automatically directs exhaust gas either
to chimney or to the economizer inlet. The flap system can be directed
to original chimney so that maintenance actions can be done for
economizer. -
Economizer chamber is insulated with double layers of walls
Advanced Automation
In automation system, PLC and touch panels are used. The working diagram and the real time temperatures and recovered energy values can be monitored on the control panel. The desired temperature of the clean process water can be set through this control panel window. Recovered energy values are recorded daily and monthly basis.
With advanced automation software, the system is protected fromthermal shocks.
