Economizer Boiler Fin Tube Application
1. A typical application of economizers in steam powerplants to
capture waste heat from boiler stack gases (exhaust gas) and
transfer to the boiler feed water.
2. This will increase the temperature of boiler feed water,
lowering the desired energy input, successively reducing the extent
needed for firing the boiler rated output.
3. Economizers lower the stack temperature will cause condensation
of combustion gases and acid corrosion serious instrumentation
injury if care isn't taken within the style and material choice.
Boiler Finned Tube Function
1. Modern boilers, like in coal power plants, still equipped with
economizers that are descendants of the initial style of the
inexperienced.
2. During this context they are usually said because the feed
hot-water tank and hot atmospheric phenomenon from the rotary
engine before it's pumped-up to the boiler.
3. Economizers are generally used as a part of the warmth recovery
steam generators in combined cycle station.
4. Within the HRSG, water passes through saver, boiler and
superheater then later. It conjointly prevents flooding saver
within the boiler with liquid water is simply too cold to boiling
given rate and boiler style.
Product Advantage
1. Add the heat exchange area and reduce the number of tubes, also
increase the fume flow section area to reduce the fume speed and
abrasion.
2. H type fin tube can be made to double H type fin tube, high
rigidness to fit long tube row.
3. H type fin economizer arranged in line to make the space into
many small zones, averaged air flow to reduce the abrasion.
4. With straight channel to gain the best ash-blowing effect.
5. The compact structure to reduce the weight and reduce the
manufacturing cost.
