Product introduction


Boiler Economizer is the Energy improving device that helps to reduce the cost of operation by saving the fuel. The economizer in Boiler tends to make the system more energy efficient. In boilers, economizers are generally designed to exchange heat with the fluid, generally water. The exhaust from the boilers is generally in the temperature range of 200°C – 250°C, so there are a huge amount of losses from the boiler if any heat recovery devices are not installed after it. Boiler Economizer that suit your boiler system and will increase its overall efficiency from 3% – 5%. Increase in boiler efficiency will save a lot of your operating cost and eventually will prolong the life of your boiler system.

 

We can manufacture three types of boiler economizer, bare tube economizer, H finned tube economizer and spiral finned tube economizer. 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 and short service time.

Technical specifications


1.Construction structure
Consists of a serious of H type finned tubes, the headers of inlet and outlet, bend, frame and other auxiliaries.


2.Structure Arrangement
In line / staggered arrangement.

 

 

Functions


1.absorb heat from high temperature gas,reduce exhaust gas temperature,reduce gas consumption,save fuel.

2.feed water is heated in econimizer before enter into steam drum,so reduce heat absorption of feed water at heating surface,which can use economizer instead of high cost evaporation heating surface and saving cost.

3.Economizer increase feed water temperature,when feed water enter to steam drum,the wall temperature deviation are decreased,the thermal stress decrease accodingly and extend working life of drum.

Variety


 

Utility Boiler Economizer

1 HDB produces economizers for utility boilers, which includes boilers fueled by coal, wood, oil, or other solid fuels to produce electricty from the boiler's high pressure steam.
2 These economizers are usually located in the back pass of the boiler and oriented with the tubes running horizontally.The boiler feedwater runs through the economizer circuits in the opposite direction of the gas flow (called counterflow).
3 Bare tubes are typically utilized in order to minimize ash fouling, but some boiler OEM's design their economizers with finned tubes, either spiral or long finned.
4 HDB can produce economizer elements with either bare, spiral finned, or long finned tubes, and if you prefer, re-design your unit to one of the other tube-types. HDB can also fabricate replacement headers for all utility boiler economizers.

 

Package Boiler Economizer

1 HDB has unique manufacturing capabilities that the Optimus engineers take full advantage of when designing sulfuric acid plant economizers and superheaters.
2 Often this allows the Optimus units to be configured for higher heat transfer efficiencies which results in a reduced surface area requirement and, consequently, a lower-priced product.
3 HDB utilizes its on-site capabilities to fin and bend the tubes, machine and fabricate the headers, drill the tubesheets, cut and prep all casing materials, and perform all of the pressure part and casing welds.
4 This gives HDB more control of the manufacturing sequence and schedule which has helped us achieve a remarkable record of on-time delivery performance.

 

HRSG Economizer

1 Economizers for today's HRSG modules are configured with fintubes that hang vertically. HDB has fabricated economizer coils for virtually all of the HRSG OEM companies and understands the unique features of each.
2 In many cases, utilities desire to upgrade their economizers from plain carbon steel to an alloy material to help resist flow accelerated corrosion (FAC) inside the headers and tube bends.
3 HDB is a one-stop shop for economizer fabrication because we prep all the materials and perform all of the pressure part and attachment welding, from finning the fintubes, fabricating the headers, and assembling the coil bundle.

*Note:HD BOILER can bespoke special type of economizer according to customer's requirement.

 

Test

1 Latest type of 'U' bending machine is used for precision cold bending of tubes.
2 Bending is done for all kind of heat exchanger, condenser, economizer, boiler tubes in Stainless Steel Seamless as well as welded.
3 Subsequent to 'U' bending tubes are hydro tested & stress relieved if asked for.
4 Also mock-up pieces are prepared for determining thickness reduction on the bend portion.
5 Dye penetrant testing on the bend portion is done ro detect cracks, flaws or any type of defect.
6 Special packing is provided to prevent any damages during transit.
