Carbon Energy Saving Steel Tubes Heat Exchanger Boiler Economizer
Economizer Description
In boilers, economizers are heat exchange devices that heat fluids,
usually water, up to but not normally beyond the boiling point of
that fluid. Economizers are so named because they can make use of
the enthalpy in fluid streams that are hot, but not hot enough to
be used in a boiler, thereby recovering more useful enthalpy and
improving the boiler's efficiency. They are a device fitted to a
boiler which saves energy by using the exhaust gases from the
boiler to preheat the cold water used to fill it (the feed water).
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.
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
