IIP-ENCON FILM BURNERS:
The basic function of an oil burner is to produce and maintain
required and consistent degree of atomisation to ensure stable
flame conditions and required heat distribution in the furnace.
Presently there are a large number of oil burners with different
designs and types and selection has to be made to suit divergent
requirements of industrial furnaces. As a consequence of survey
carried out by different national agencies viz IOC, NPC, DGTD,
it was observed that nearly 70% of Industrial Units use low
air pressure atomising type burners.
In view of the inherent limitations in the Lap Burners available
in the market using almost 25-30% of excess air for proper atomisation
and combustion, it was felt that there was considerable scope
for improving the performance of existing Lap Burners by use
of lower levels of excess air & wider turn down ratio. Thus
an improved version was developed by IIP in association with
PCRA after several years of sustained R & D work. These
improved low excess air film burners developed by the above
agencies give a fuel saving of 10-15% by using extra excess
air below 10%.
Encon International were granted the licence on request for
manufacture and marketing of these burners which over the years
have been marketed in great numbers to the user industries and
have shown excellent results wherever in use.
The unique features responsible for its astounding success lies
in the process of atomisation of fuel which gets reduced to
a very thin film in the form of a hollow cylinders inside the
burner and on release of primary air at about 700 mm w.g. partly
from centre and partly above this oil film dividing the oil
into fine globules to result in efficient atomisation. By this
improved version the fuel saving as indicated has been made
possible.
Other salient features of Encon Film Burners are that it has
wider turn down ration of 7:1 operates at low excess air levels
for improved fuel economy as above and reduce scale/burning
losses.
IIP-ENCON FILM BURNER; SALIENT FEATURES
1. Operates efficiently at low excess air levels. 5-10% against
25-30% of L.A.P burners presently available.
2. Reduces stack losses and improves fuel economy. saves upto
20% fuel.
3. Wider turn down ratio 7:1 against 3:1 obtainable in presently
marketed enhanced fuel economy benefits.
4. Can be used with preheated air upto about 250-300 Deg.C.
Thus, giving enhanced fuel economy benefits.
5. Can be installed in existing L.A.P fuel oil systems without
any significant changes.
2. WASTE HEAT RECOVERY SYSTEMS-RECUPERATORS:
In view of the rising cost and lower supply of fuel oils all
over the world an acute need to conserve the available fuel
resources has been felt to offset the slackening Industrial
and economic growth. It thus becomes imperative to resort to
efficient utilisation and economy in the use of fuel oils. This
requirement stared on the face of Indian Economy where importation
of fuel oils depended to a very large extent.
While fuel economy was possible by 5-10% on proper storage,
handling and preparation of furnace oil, further economies could
be achieved by waste heat utilisation systems. Most Industrial
furnaces operate at high temperature and allow flue gases to
escape at a temperature of 600-900 Deg.C allowing significant
percentage of fuel between 35-50% input as wastage to the atmosphere.
Preheating of combustion air is the most commonly used method
of waste heat recovery in almost all types of furnaces. Care
has to be taken that the preheated air range between 250-500
deg. C depending on what the burners can withstand. The lap
type burners fitted on most of the furnaces have a limitation
of preheated air temperature of 250 Deg.C.
Encon Recuperators have been successfully used in a number of
industries for utilisation of waste heat from boilers and thermic
fluid heaters. In case where such equipments are being used
on coal and forced draught system, the saving in coal consumption
is more than 25%.
Encon Recuperators which preheats the combustion air from the
escaping flue gases to a temperature of 200-250 Deg. C results
in recycling of waste heat back to the furnaces to give saving
of 12-15% of furnace oil. The normal pay back period on installation
is just 5-7 months. Encon Recuperators have been developed and
are being marketed to meet the requirement of steel, forging,
heat treatment and aluminium industries etc in the country.
3. ENCON FUEL COMBUSTORS (BLOWER)
ENCON Centrifugal Steel Plate Air Blower is
designed to give optimum CFM volume and pressure of air with
low power consumption. Although originally they are designed
to supply air to Combustion systems, they can be used on any
application requiring low pressure air.
Each impeller is dynamically balanced before assembly. All blowers
are equipped with TEFC, squirrel cage, Induction motors of reputed
make such as NGEF, ABB, Crompton etc. Options of direct drive/shaft
driven through "V" Belts. Individual units undergo
rigorous testing prior to shipment.
FEATURES:
Rigid construction
Statically and dynamically balanced
Quiet
Field adjustable discharge position
Capacity range: 3 HP-60 HP (Higher capacities on request)
Pressure: 6" w.g-44" w.g.

HEATING & PUMPING UNIT |
The
Heating and pumping unit is especially designed to give
a pre-heat to the fuel at the required pressure. The excess
fuel, which is not used, is returned back to the heating
and pumping unit, which is called a ring main system. This
system gives the advantages that whatever is the excess
fuel, which is not required by the burner is returned back
to the heating and pumping unit.
|
The
Duplex models give the advantage that only one fuel pump
is working at a time, whereas the other pump is as stand-by,
in case of any accidental failure of the working pump.Each
unit is fitted with standard heavy-duty fittings and tested
for pressure flow and heating capacity.
