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.

 

Manufacturing and acceptance criteria

 

· JB/T6512 "boiler with a high-frequency resistance welding spiral fin tube manufacturing technology conditions"
· HG/T3181 "high-frequency resistance welding spiral fin tube"
· JB/T6511 "spiral finned tube test technical conditions."
· JB1611 "boiler tube mane box assembly conditions"
· JB/T1612 "boiler pressurufacturing conditions."
· JB16I3 "boiler pressure parts welding conditions."


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

 

Internal heat exchangers

 

1.Subcooling may also be produced by superheating the gas leaving the evaporator and heading to the gas compressor.

2.These systems withdraw heat from the liquid line but heat up the gas compressors suction.

3.This is a very common solution to insure that gas reaches the compressor and liquid reaches the valve.

4.It also allows maximum heat exchanger use as minimizes the portion of the heat exchangers used to change the temperature of the fluid,and maximizeds the volume in which the refrigerant changes its phase.

 

Competitive Advantage

 

1.Fuel saving: After the high temperature fuel gas released by fuel combustion transfers to the boiler water wall tubing, superheater, and reheater, the temperature is extremely high, the economizer makes it ideal for preventing heat loss. The economizer located at the flue of the boiler reduces the flue gas temperature, and maximizes the heat recovery to lower customer fuel costs.

 

2.Improvement of boiler steam drum working conditions: When entering the steam drum, the temperature of the feed water is increased after it has been heated using the economizer. The thermal stress caused by the temperature difference between the steam drum wall and the feed water is reduced, thus reducing the shrink and swell of the steam drum, and extends the service life.

 

3.Cost reduction of coal fired boilers: Water is being heated in the boiler economizer made using low temperature material. This makes the economizer a less costly replacement for high temperature boiler water wall tubing, and reduces overall boiler manufacturing costs.

Working Process of Boiler Economizer

 

There are three stages from the feed water in the boiler heated into superheated steam:feed water preheating, evaporation, and superheating. The three stages are finished on three different heating surfaces. The boiler steam and water circuit are composed of the three different heating surfaces as well as their connecting pipes. Boiler economizers are one of them, and it is right the equipment to preheat the feed water. Thus, it is the heating surface with the lowest temperature for boiler working fluid in the boiler steam and water circuit. The working fluid passing through this equipment is monophasic water(non-boiling economizer).
