ASME Standard Hot Water Boiler Stack Economizer Tubes For Utility/Power Station
Economizer Description
HDB consistently executes successful boiler economizer installations using safe, cost-effective methods. Economizers improve boiler performance by increasing fuel efficiency and improving steam generation and response time.
We can guide you through the process of installing or retrofitting existing boiler systems .
Our expert boiler economizer and waste heat recovery system installations can reduce your overall fuel requirements, lower emissions, and ultimately reduce your boiler operating costs.
Function
The economizer is a steam generation system as like a boiler. when the exhaust gas discharge from the engine cylinder through the exhaust valve it goes to the boiler for generate steam by heating of water.
After those gas it goes through the economizer the remaining exhaust gas temperature is heated the water in economiser. it help to generate steam, and it is improving the efficiency and save the fuel consumption
An economizer uses the waste heat from the boiler exhaust, that would otherwise be lost to atmosphere to (in most cases) preheat the feed water into the boiler.This improves the boiler efficiency and reduces fuel costs.

Material Structure
Consists of a serious of spiral fin tubes, the headers of inlet and
outlet, bend, frame and other auxiliaries.
Structure Arrangement
In line / staggered arrangement.
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. |
