Exhaust gas condensers and economizers,

Warmtetransport.nl is your partner for the supply of exhaust gas condensers and economizers.

The exhaust gas condenser can pre-heat the water for the boiler or an other fluid stream by recovering the condensation heat from the water of the exhaust gasses. Depending the temperature of the water through the tubes condensation of the exhaust gas takes place. This heat recovery system can improve the efficiency of the boiler significantly.

The exhaust gas condenser is installed upstream the boiler or economizer and is build with SS tubes and often with extruded aluminum or SS fins in more sections in series. Instead of finned tubes bare tubes can be use as well in condenser. The (finned) tubes are welded or rolled in SS tubeplates or welded to 180° bends( “hairpins”)

The heat exchanger is preferably build as “pull out” design for easy inspection, cleaning and/or replacement. The casing of the module, with SS stiffening ribs, is made from SS as well.

Together with our associates we can deliver swiftly and reliable. We can also do the assembly, installation and commissioning of the applicable heat exchangers in close cooperation with f.i. Stoomwezen or other third party inspectors.

The Standard execution of the exhaust gas condenser:

·         SS 316(L) tubes with Aluminum “extruded” fins.

·         Module casing in SS 316(L) or equal.

·         Heat exchanger of the “pull-out’ design.

·         Heat exchanger with “Hairpin” design, to guarantee stress free expansion of the tubes.

The economizer can pre-heat suppletion water for the boiler by using the heat from the exhaust gasses. Economizers function on a higher temperature range, and are classified according the PED as a pressure vessel and subsequently needs a CE marking.

The economizer is placed between the boiler and the chimney and consist of steel tubes with steel or aluminum fins in more sections in series. . The (finned) tubes are welded or rolled in SS tubeplates or welded to 180° bends( “hairpins”)

The heat exchanger is preferably build as “pull out” design for easy inspection, cleaning and/or replacement. The casing of the module is regular steel and conserved with a suitable high temperature painting system.

The exhaust gas condensers and economizers are normally delivered together with the necessary support structure, and with the required exhaust gas valves and/or with an extra chimney.

The Standard execution of the economizer: 

·         Steel tubes ( St.35.8-I) with steel or aluminum fins.

·         Module casing steel (St.37) or equal.

·         Delivery according PED with CE marking.
