Carbon Steel Seamless Tube Economizer For Boiler Heat Exchanger ASME Waste Heat Energy
Quick Details Specifications
| Specification of Economizer for Boiler Exhaust heat loss is the largest of the heat loss of the power plant boiler, usually 5% to 8%, accounting for 80% of the total heat loss of the boiler or higher. |
| The main factors that affect the heat loss of the exhaust gas are the boiler exhaust temperature. Under normal circumstances, the exhaust heat temperature increases by 10 ℃ and the exhaust heat loss increases by 0.6% ~ 1.0%. |
| China's current thermal power units in the boiler exhaust gas temperature is generally around 125 ~ 150 ℃, the actual smoke temperature is higher than the design value is ubiquitous phenomenon. |
(1) 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.
(2) 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
(3) 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.
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.

*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.

Boiler Industrial SA210A1 Steel Boiler Economizer Heat Exchange Part ASME Certification
Boiler Industrial SA210A1 Steel Boiler Economizer Heat Exchange Part ASME Certification Introduction The H-shaped finned tube is also known as the H-shaped fin tube, also known as the butterfly fin tube. It is to weld symmetrically two pieces of steel with an arc in the middle to form fins (ribs or butterflies), the frontal shape of which resembles the letter "H", so it is called the H-shaped finned tube. The two fins of the H-shaped fin tube are rectangular and approximately
