Customized Heat Exchanger Tubes Boiler Economizer With Stable Performance
Economizer Description
Boiler economizers are heat exchange devices with finned tubes that
heat a liquid, sometimes water, up to however sometimes doesn't
exceed the boiling purpose of liquid.
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.
We can manufacture types of boiler economizer, bare tube
economizer, H finned tube economizer and spiral finned tube
economizer and gilled tube economizer.
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 .

The Accessory
The boiler economizer acts as a waste heat recovery device,
ensuring that this heat does not go unused.
Instead, the heat is used to essentially preheat the water, so that
less heat is required to bring the water to a temperature high
enough to make steam
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.
