Highly Efficiency Boiler In Thermal Power Plant , Power Plant Economiser Easy Operation,ISO/ASME Certification
Product Introduce
Economizer Economizer is installed on the lower part of the boiler tail flue for recycling the waste heat of smoke, a device heating boiler feed water into steam drum pressure of saturated water heating surface, due to its high temperature flue gas heat, reduces the exhaust temperature of flue gas, save the energy, improve the efficiency, so called the Economizer.
The steel-pipe coal saver is not restricted by pressure and can be used as a boiling type, which is generally controlled by carbon steel with an outer diameter of 32 ~ 51 mm.Sometimes the fin and fin are added to the tube to improve heat transfer.The steel-pipe coal saver consists of parallel curved pipe (called serpentine pipe) arranged horizontally.
The coal saver is mainly used for industry, and it is gradually applied to agriculture and some related industries.
Steam boiler economizer can be made of alloy steel, carbon steel or other kind of material as per the customer’s requirements. It conforms to the standard of ASTM, EN, DIN, GB. The manufacturing equipment is 30~185MN hydraulic press, the forging ratio >3,
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 manufactured by our company can guarantee the wall temperature is 5-10 ℃ higher than the acid , and flue outlet temperature is 10-15 ℃ higher than the wall surface temperature
3. Wall surface temperature can be adjusted according to the boiler load and fuel changer to avoid corrosion under low temperature
4. Changer the DCS system of the existing boiler to achieve the auto and remote control by computer.
Features
(1) the economizer is a heat exchanger that USES waste heat from boiler smoke exhaust to heat water supply;
(2) the economizer absorbs waste heat of exhaust smoke, reduces the exhaust temperature and improves the efficiency of the boiler;
(3) due to the water supply entering the drum, the water temperature has been raised through the economizer, and the thermal stress on the wall of the drum caused by temperature difference has been reduced, thus improving the working conditions of the drum and extending the service life of the drum.
Specifications
| Description | Heat boiler economizer, steam boiler economizer, oil boiler economizer, coal steam boiler economizer, Gas boiler economizer,etc |
| Material | Alloy steel, Carbon steel, SA210C ,SA213T22, etc. |
| Material standard | ASTM, EN or ISO etc. |
| Dimension | Customization |
| Weight |
Min: 10 ton |
| Smelting Process: | EF+LF + VD |
| Process | Material→Ingot → Hot/Cold-Rolling→ Heat treatment (Normalizing+ tempering) → Inspection →rough machining→UT →2nd Heat treatment →finishing machining →Inspection |
| UT standard | ASTM A388 or EN10228, etc |
ADVANTAGES
1. The economizer is to heat the boiler feed water (softened water) to raise the feed water temperature, instead of heating the boiler water.Absorbing the waste heat of flue gas to heat the boiler, reducing the heat loss, improving the efficiency of the boiler and saving coal accordingly.
2. The economizer shall install the safety valve and temperature gauge separately. In case of water shortage accident of the boiler, the bypass waterway of the economizer shall be opened immediately and the inlet and outlet of the economizer shall be closed.
3. The feed water is heated in the economizer before entering the evaporative heating surface to reduce the heat absorption of water in the evaporative heating surface, which is equivalent to replacing part of the evaporative heating surface with the economizer.
4. The heating surface of the economizer is much cheaper than that of the evaporating heating surface.
