EEI has designed, factory-made and provided air preheaters with the heating price from 4000 kcal/hr to eighty,90,000 kcal/hr.

3.  EEI has designed, factory-made and provided air preheaters with the
heating price from 4000 kcal/hr to eighty,90,000 kcal/hr.
 An Air pre-heater is intended to heat up air before
another method with the first objective of skyrocketing the
thermal potency of the method.

4.  The Air pre-heating helps in Igniting the fuel, up combustion,
Reducing the stack gas temperature and increasing the
boiler potency.
 Stability of Combustion is improved by the utilization of hot air
through the Air Preheater.
 because of High heat transfer rate within the chamber and lesser
heat transfer space needed. there'll be lesser un-burnt fuel particle
in flue gas that the combustion potency is improved.

5.  To maximize the boiler potency the helpful heat has got to be off
from the gas from the APH. but bound minimum temperature has
got to be maintained within the flue gas to
stop cold finish corrosion.
 associate air preheater heats the combustion
air wherever it's economically possible.

6.  Air preheaters are often classified as restorative Air Preheaters and
Regenerative Air
Preheaters varietiessupported their operative principle.
 In restorative Air preheaters, the heating medium is on
one aspect and therefore the air is on the opposite aspectof the tube
or plate and therefore the heat transfer is
by conductivity through the fabric that separates the media. In
regenerative Air preheaters kind the warmthing medium flows
through a closely packed matrix to lift its temperature then air
is more established the matrix to maximise the heat.

7.  Steam Coil Air Preheater (SCAPH)
EEI has provided Steam Coil Air Pre-heater (SCAPH) having
heating price from 15500 Kcal/hr to thirty five,45,900 Kcal/hr.

8.  Steam coil air preheaters (SCAPH) ar accustomed heat air coming
into the air heater restorative or regenerative kind, so as to
lift the common cold finish temperature to
stop acid temperature corrosion.

Finned varieties SCAPH ar wide accustomed increase the air
temperature from close to the requisite temperature level
by means that of saturated steam as heating medium. Steam
flows within the tube whereas air passes over the finned tubes.

9.  SCAPH is employed with High capability Boilers, Recovery Boilers,
and Dryers for heating process-air in Sugar producing, Chemical &
Allied Industries
SCAPH is generally incorporated into the planning of a boiler unit for
low load operation and startup operation notably in those areas with
low close air temperatures.
 they're fascinating in this the most air heaters, restorativeor
regenerative, have corrosion sections that ar a lot
of promptly maintained.

10.  Finned kind SCAPH form of air heater uses extended
surface, unremarkably cited as fins, to scale back the size of the
air preheater.
 it's usuallyplaced within the duct between the FD fan and
therefore the main air heater; it's common to possess this earlier
than the FD fan that might heat up cold winter air up
to regarding forty degrees F.
Recuperative hollow Air Preheater
EEI has designed and made hollow Air Preheater with heat
duty starting from 4000 kcal/hr to eighty,90,000 kcal/hr.

11.  The heat is recovered by the air from the new gas flowing across
the air preheater. These form of air
preheaters aris encircled rectangular kind construction
consisting of many sizable amount of steel tubes of forty to sixty
fivemillimetre DIA. connected or distended into the tube plates.
Flue gas that is that the heating medium passes
through inside the tubes and therefore the air
passes although the surface of the tubes. the warmth transfer
surface is giant because of low heat transfer constant between
flue gas and air. Vertical flow is recommended to avoid fouling.

12.  Tubular air preheaters and hollow Air Preheater with
baffles ar designed, factory-made and provided to variedboiler
industries as heat recovery units and conjointly to produce hot
combustion air to the chamber.
