Air Preheaters are used as heat exchangers
for heating, evaporating, cooling and condensing and also for heat recovery in
a large number of industries. The reason for the worldwide acceptance of air
preheaters are their high thermal effectiveness, effective leakage control
properties, proven reliability and performance, compactness of their design and
their adaptability to any fuel burning process.
Available in a broad range of arrangements
and size, air preheaters are engineered to meet specific requirements and
operating conditions of a variety of applications. The industries in which air
preheaters are used are follows:
·
Electrical power generating
plants
·
Package and large industrial
boilers
·
Fluidized bed boilers
·
Waste incinerators and drying
industries
·
Flue gas and reheating
industries
There are different types of airpreheaters. Finned-tube preheaters can be made from a wide range of materials
like steel, stainless, copper/aluminum, aluminum and other special materials.
Again, there are plain-tube preheaters which are used when a fluid present
around the tubes is so polluted that finned tubes can no more be used. Plain
tubes have the probability of getting configured in different way either next
to each other or serially.
