Horizontal Carbon Steel Pressure Parts Economizer In Boiler For Power Station
Horizontal Carbon Steel Pressure Parts Economizer Product
Description
1. 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
three types of boiler economizer, bare tube economizer, H finned
tube economizer and spiral finned tube economizer. H-finned tube
economizer is high efficient heat exchanger economizer which is
consisted of H-finned tubes.
2. 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.
3. 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.
Advantages
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.
