Boiler economizers are heat exchange devices with finned tubes that heat a liquid, sometimes water, up to however sometimes doesn't exceed the boiling purpose of liquid.
We can manufacture three types of boiler economizer, bare tube economzier, H finned tube economzier and spiral finned tube economzier.
|Tube OD:||32, 38 or according to customer's needs|
|Material||carbon steel, alloy steel|
H-finned tube economizer is high efficient heat exchanger economizer which is consisted of H-finned tubes.
Compared with bare tube economizer, H-finned tube economizer can enlarge the heat exchange area and reduce the number of tubes. It also can increase the flue gas flow area in order to reduce the flue gas flow speed and abrasion.
H-finned tube can be made as double H finned tubes , with high rigidness to fit long tube row.
The spiral finned economizer is a newly designed heat transfer equipment, consists of spiral fin tubes to overcome the serious abrasion anh short service time.
Main technical advantages of our low temperature economizer
1. The equipment body can be designed into many modules to ensure the long term and stable running;
2. The low temperature economizer manufatured by our company can guarantee the wall temperature is 5-10 ºC higher than the acid , and flue outlet temperature is 10-15 ºC higher than the wall surface temperature
3. Wall surface temperature can be adjusted according to the boiler load and fuel changer to avoird corrosion under low temperature
4. Changer the DCS system of the existing boiler to achieve the auto and remote control by computer
Modern boilers, like in coal power plants, still equipped with economizers that are descendants of the initial style of the inexperienced. during this context they are usually said because the feed hot-water tank and hot atmospheric phenomenon from the rotary engine before it's pumped-up to the boiler.
